How Often Do I Need Heat Pump Maintenance?

August 31st, 2020
Heat Pump

Heat pump maintenance is critical to the performance, energy efficiency and longevity of your Lansing area home’s heat pump system. These popular HVAC systems offer both cooling during the warm months and heating for the cold ones. Because they’re used for more of the year than an air conditioner or furnace, there may be some confusion regarding how often heat pump maintenance should be performed.

Because you rely on the heat pump for year-round indoor comfort, maintenance for your system must be a priority. In this blog, the NATE-certified technicians at A-1 Mechanical explain how frequently tune ups are required and detail the maintenance care your system needs to stay in top shape.

How Frequently Is Heat Pump Maintenance Needed?

As mentioned above, heat pumps pull double duty in Michigan homes, delivering both heating and cooling. Because they run most of the year, they experience more wear and tear. Because of this, heat pump service is recommended two times per year for residential units.

When Should Heat Pump Tune Ups be Performed?

Just like maintenance for air conditioning units and furnaces, heat pump tune ups should typically be performed in the spring and fall – once before warmer weather arrives and again before winter. This timing ensures the tune up is completed before entering periods of heavy use. A tune up will prepare your system to perform efficiently when needed, and issues in need of repair can be resolved before you’re surprised with a heat pump malfunction when you turn it on for the first time each season.

What Does a Heat Pump Tune Up Include?

A professional heat pump maintenance tune up includes many steps that work to enhance energy efficiency, improve performance levels and prevent future repairs. These steps include:

  • Airflow measurement through the system
  • Verification of refrigerant charge
  • Inspection of refrigerant lines
  • Tightening and cleaning of electrical connections
  • Lubrication of motors
  • Inspection and tightening of belts
  • Testing startup, shutdown and other controls
  • Verification of thermostat operation

A-1 Mechanical’s Residential Preventive Maintenance Plans make it easy to stay on top of your heat pump’s maintenance requirements. Join today and you’ll receive two yearly system tune ups plus other valuable services and discounts.

Maintenance Steps for Homeowners

In addition to two yearly tune ups, your home’s heat pump requires additional care from you throughout the year. These tasks are easy to perform as part of your regular home maintenance routine.

  • Change the air filter on a regular basis. Check the recommended replacement frequency given by the filter manufacturer and visually assess the existing filter monthly so you’ll know when a replacement is needed.
  • Keep the outdoor unit free of debris. Remove grass clippings, mulch and other yard waste that accumulates on the unit’s fins. Remove any vegetation growing along the unit, and trim back shrubs to provide at least 24 inches of clearance surrounding the unit.

Air Conditioning Systems: When to Repair vs. Replace?

August 31st, 2020
Air Conditioning

Determining whether to repair or replace your air conditioning unit is not always an easy call. While repairs are generally lower in cost, this choice isn’t always preferred. Replacing an air conditioner is a major investment, but the benefits may be just what your family needs.

How do Greater Lansing area homeowners decide whether to repair or replace air conditioner equipment? A-1 Mechanical shares the factors you need to consider when faced with cooling system issues so you are able to make an informed choice that best fits your family, both now and in the future.

When Is It Better to Repair or Replace Air Conditioning Units?

From one home to another, every situation is different. Air conditioner repairs may be a wise option for one family, while replacement is the better choice for another. There’s no set list of criteria we can use that tells us when it’s best to repair or replace air conditioner equipment, but there are some guidelines that help guide this important decision. Your technician is able to advise you regarding specific issues and factors that pertain to your AC unit and how each may affect these general guidelines.

Air Conditioner Repair Is Typically the Best Option If…

The unit is still under warranty

The manufacturer’s warranty pays the cost of parts, while a labor warranty provided by the original HVAC installer covers labor required for repairs. If your manufacturer’s warranty is still valid, the repair it needs may be covered. If your labor warranty is still valid, the repair may come at no cost to you! In situations where a valid manufacturer’s warranty covers parts but the labor warranty has expired, the cost of the repair is still greatly reduced as you only need to pay labor costs, which makes the repair less of a financial burden.

The unit has been in service less than 8 to 10 years

An AC unit typically lasts 10 to 15 years. If your air conditioner is just a few years old and requires simple repairs, it doesn’t make financial sense to replace it yet.

The repair will improve system performance

If the required repair will boost air conditioner performance and energy efficiency for several years, repairing the system is the more affordable option.

The unit has been well maintained

Well-maintained AC units typically last longer and have fewer breakdowns. If the system has been properly cared for over the years, repair needs are often isolated while the overall system is in good shape.

The unit’s age multiplied by the cost of repairs is less than the cost of replacing the system

Cost is a major factor when homeowners have to choose to repair or replace air conditioner units. This formula can be used to help you determine if a repair is a wise financial investment or if your money is better spent when used for a new air conditioner.

Air Conditioner Replacement Is Often Preferred When…

The unit has been in service 10 or more years

When it comes to replacing your AC, system age should always be considered. As air conditioners only last an average of 10 to 15 years, replacement is typically the better option when an older unit is in need of repairs. Replacement is already on the horizon, and taking care of it now helps prevent surprise failures that leave the home without much needed cooling. Upgrading to an energy-efficient system will also reduce monthly energy bills.

The system uses R-22 Freon refrigerant

The type of refrigerant used has become an important consideration in the decision to repair or replace air conditioners. As of January 1, 2020, no new R-22 (Freon) refrigerant can be produced or imported, leaving only recycled refrigerant available for system repairs. With a limited supply of refrigerant on the market, costs for recycled refrigerant are quite high. When needed repairs involve recharging the air conditioner’s refrigerant levels, you should strongly consider replacing the system with a unit that uses R-410A refrigerant to avoid high prices. Plus, if your AC unit uses R-22, then it was built before 2010 and is already aging.

The required repairs cost more than half the price of a new air conditioner

If the cost of repairs totals more than half the cost of a new cooling system, most homeowners feel their money is better spent investing in a new unit.

The unit requires frequent repairs

More frequent repairs are typically required when air conditioners hit the final two or so years of their service life. If multiple repairs have been made over the last year or two, this is a sign that system failure is on the horizon, so go ahead and replace the unit now.

The unit is undersized or oversized for the home

When repair issues stem from improperly sized air conditioners, unfortunately there is no repair solution. In the decision to repair or replace air conditioner units, replacement is the only option to deliver an accurately sized unit that is able to deliver efficient performance and accurate temperature control.

Can’t Decide? Call A-1 Mechanical for Professional Guidance!

Knowing when it’s time to replace air conditioner equipment can be a tough decision to make, but you don’t have to decide blindly! Consult our NATE-certified air conditioning technicians for thorough diagnostics to pinpoint system issues and receive professional advice to help you decide whether to repair or replace the AC unit in your Lansing area home.

How Often Should I Change My HVAC Air Filter?

August 11th, 2020
Heating

Do you know how often to change your HVAC system’s air filter? There is no one set answer for all Grand Rapids area homes, as many different variables come into play affecting the service life of a furnace filter.

How often you change your home’s HVAC air filter depends on how long your filter is expected to last and the different qualities of your home that impact the filter. When in doubt, call A-1 Mechanical for expert advice and indoor air quality services for your Michigan home.

How Long Do Air Filters Generally Last?

As mentioned above, there is no set service life for an air filter – it requires an evaluation of many different aspects. Air filter manufacturers include a recommendation for how often to change air filters. You can find this information on the product insert that comes with a new filter. Furnace filters are expected to last anywhere from one month to one year.

  • 1-inch and 2-inch air filters should be replaced about every one to three months
  • 3-inch and 4-inch filters require replacement after six to nine months
  • 5-inch and 6-inch air filters need a change after nine months to one year


Factors Affecting How Often to Change HVAC Air Filters

The manufacturer’s recommendation isn’t the final answer on how frequently you should change your furnace filter. The biggest factors affecting filter service life are detailed below.

Pets in the Home

Indoor pets shed hair and dander that easily become airborne in your home. These materials clog air filters faster. Homes with one pet should generally replace filters after two months; those with more than one pet may need to replace the filter monthly.

Heating & Air Conditioning System Use

How frequently your heating or air conditioning system is in use impacts filter service life as well. During periods of the year when HVAC equipment runs often, air is circulated more times through the home compared to times when the HVAC system is used sparingly. More cycles mean more passes through the filter and opportunities to trap contaminants, so filters typically fill up faster during high-use periods.

At the peak of summer and winter, air filters need to be changed more frequently than required during the spring, fall and the milder months.

Allergy & Asthma Sufferers

If there are allergy or asthma sufferers in your household, clean air is critical to their health and comfort indoors. You’ll need to change your HVAC filter more frequently when allergy and asthma sufferers are present. Changing the filter on a more frequent basis ensures the filter has the available surface area needed to filter out the contaminants that trigger symptoms among your loved ones.

Have Questions? A-1 Mechanical Is Here to Help!

Estimating how often to change an air filter can be tricky because of so many different variables at play. If you’re unsure how often your furnace filter requires replacement, call A-1 Mechanical! Our knowledgeable team of NATE-certified HVAC system technicians is always available to assess the indoor air quality needs of your home and help you create a plan for cleaner air indoors, from an accurate filter replacement schedule to installing advanced filtration solutions.

Tips for Hiring a Reputable HVAC Company

August 11th, 2020
Hiring HVAC

Hiring a heating and cooling company often seems like a difficult task, especially for Grand Rapids area homeowners who’ve not required the services of an HVAC technician in the past. With many HVAC service providers in our area, how does a homeowner go about making this tough decision?

Choosing the right contractor makes all the difference when hiring an HVAC company to perform work at your home – the integrity of your home and HVAC equipment are on the line. The NATE-certified technicians at A-1 Mechanical will tell you what to look for as you evaluate area heating and cooling companies so you are able to determine which ones are credible.

Where to Start Your Search for an HVAC Company

If you have never worked with an area HVAC company before, it’s difficult to decide where to start your search, with so many local providers of heating and air conditioning services. We recommend that you turn to your greatest resource for recommendations – those you know and trust.

Seek out your friends and family and even trusted coworkers or neighbors and ask which area HVAC companies they’ve worked with in the past. From these sources, you’re most likely to receive a candid review of various local contractors. Find out which companies they liked and didn’t like, how their experiences were with each business and which companies they would hire again.

Qualities of Reputable HVAC Companies

Before choosing an HVAC company, take the time to research area contractors and learn more about their businesses. Here are the qualities to look for:

  • Contractor’s license: Under Michigan law, a mechanical contractor’s license must be held by any company performing repairs, installation or alterations of heating, cooling, ventilation or refrigeration equipment and systems. Before choosing an HVAC company, verify the contractor’s license is valid using the state’s license search.
  • NATE certification: NATE (North American Technician Excellence) is an independent certifying organization for the HVACR industry. Technicians can voluntarily obtain NATE-certified status by passing NATE’s rigorous exams to prove his or her knowledge and technical skills. Certifications must be upheld by meeting ongoing educational requirements. As a homeowner, working with an HVAC contractor who employs NATE-certified technicians is to your advantage – NATE-certified technicians are well versed in industry principles and advancements, and their skills have been proven, ensuring you receive high-caliber service for best results.
  • Brands: Different companies work with different brands of heating and cooling equipment. If you need repairs or maintenance, you want to be sure a particular company services the make and model of your existing heating and air conditioning system. If you need new installation of a heating and cooling system, look for a contractor who offers the brand you’re looking for or a wide selection of systems to choose from.
  • Written estimates: Before hiring an HVAC company, it’s wise to request written estimates from around three different contractors – this allows you the opportunity to meet with and interview the company in person and compare bids between providers. Don’t hire a company that won’t provide you with a written estimate. In the HVAC world, it’s pretty much impossible to provide an accurate estimate of work over the phone – with little detail regarding your home – so the price won’t be correct if the contractor hasn’t visited the jobsite in person. With a written estimate in hand, you know what work is proposed and what to expect out of the contractor.


Before Hiring an HVAC Company

As you gather information and meet with select local HVAC contractors, it’s also recommended that you take a look at the company’s reviews to see what other customers have to say about their experiences. Online review sites such as Google, Yelp and others offer information that you won’t get from the company’s list of chosen references, whether it’s good, bad or ugly.

An issue all homeowners must consider when browsing reviews is that these sites are sometimes used as sounding boards for disgruntled customers. While you want to know if someone had a bad experience with the company, beware that comments are sometimes made hastily out of frustration, and sometimes before the company had the opportunity to right any wrongs. The negative reviews can be just as valuable to your decision as all the praise a company gets. Look closely at how the HVAC contractor handles upset customers. Look for professionalism, attempts to correct the situation and attentiveness.

Why Is My Air Conditioner Making Noises?

June 26th, 2020
Air Conditioning

Home AC compressor noises are concerning to any Grand Rapids, MI, area homeowners who experience this sudden and unexpected disturbance. A little noise from your outdoor air conditioning unit is normal as it runs, but beyond this steady, typical operating noise, certain sounds are indicators of problems within your cooling system.

A-1 Mechanical’s cooling professionals explain the different types of air conditioner compressor noises that point to malfunction. If you notice any of the sounds below from your cooling system this summer, please contact us right away to schedule an air conditioner repair visit.

What Air Conditioner Noises Mean Potential Trouble?

Most homeowners are familiar with the hum of their air conditioner’s cycling. Any sounds that are new and interrupt that usual drone are signs of potential system trouble, and the type of sound is a clue as to what could be malfunctioning within the cooling system.

Here are the different types of noises that you may hear and what they mean:

1. Banging, Rattling or Clunking

Banging, rattling or clunking noises that occur when the cooling system runs often indicate loose parts. If a bolt comes loose, the compressor isn’t held firmly into place and produces such sounds due to movement. Tightening the connection is the first step in eliminating the noise, if applicable.

Loose connecting rods, pistons or other components move around during operation and produce the air conditioner compressor noise you hear during a cooling cycle. Compressor replacement is often recommended to correct this issue. Due to the assembly of this vital component, it’s usually easier to replace the compressor than attempt to repair the loose internal component.

2. Clicking

A clicking noise is usually caused by some sort of obstruction. Branches and other outdoor debris that fall into the unit cause such a sound as they prevent internal components from functioning properly. These items can damage internal components, causing them to produce an unusual noise while the system runs, such as the compressor fan blades striking against a bent fan screen as they rotate.

Debris must be removed, and any damaged components inside the condenser unit repaired. Exterior components of the unit may have sustained damage due to falling debris, which also require repair. Component replacement may be necessary if a part is damaged beyond repair.

Another issue that causes a clicking noise is a malfunctioning relay or control within the exterior unit. Controls and relays are tested to determine performance problems and then repaired or replaced to restore function and eliminate the clicking noise you hear from your outdoor air conditioning unit.

3. Hissing

Is your air conditioner making high pitched hissing noises? It could be an indication of two different yet serious issues. Other AC noises that often occur along with hissing provide a clue as to the source of the problem.

  • Hissing and bubbling are indicative of a refrigerant leak within the outdoor unit. Technicians inspect the system to locate the leak and perform repairs to seal the line, which eliminates the hissing and bubbling caused by escaping refrigerant and pressure.
  • Hissing, along with a screaming noise from the outdoor unit, point to a dangerous buildup of pressure. Turn your air conditioner off right away if you hear these sounds and do not use the system again until repairs are completed. High-pressure buildup within an AC compressor is often caused by a leaking or damaged thermostatic expansion valve or other valve in the compressor’s fan motor. The compressor’s high-pressure sensor may also be broken if it fails to shut down the system when high pressure is present.


A-1 Mechanical Ends Home Air Conditioning Compressor Noises Fast

If you notice that your air conditioner is making a noise that isn’t typical this summer season, make sure to call A-1 Mechanical to schedule an air conditioning repair appointment right away. Our technicians are available around the clock to quickly perform repairs to malfunctioning components, eliminating the disturbance and restoring the proper function of your cooling system’s vital parts.

Why Does My Air Conditioner Smell So Bad?

June 26th, 2020
Air Conditioning

Have you noticed a funky odor in your Lansing or Grand Rapids area home lately? If the unwelcome aroma persists despite your best efforts to banish it through extra cleaning and other measures, the source could be something you never thought to consider – your air conditioner.

When an air conditioner smells bad, it leads to a lingering odor and an issue many in the HVAC business refer to as dirty sock syndrome – named after the distinctive smell it produces within the home. A-1 Mechanical explains the source of this unpleasant problem and what to do to rid your home of the stench.

The Reason Your Air Conditioner Smells Bad

A smelly air conditioner and the resulting dirty sock syndrome often stems from mold and mildew within the cooling unit. Your evaporator coil can easily become a prime location for this unwanted growth and collection. Moisture produced through cooling air – combined with poor air filtration and collecting debris deposited by cycling air – deliver prime conditions for mold and mildew to develop and linger.

Issues That Cause Air Conditioner Odors

As explained, the development of mold and mildew produce the foul odor experienced all the way inside the home. Mold isn’t supposed to grow and thrive in a home’s air conditioner. If your AC smells bad, you need to pay close attention to the areas below. Take action to prevent these problems in your Grand Rapids or Lansing area home, and stop cooling system odors from seeping into your living areas.

Inadequate Filtration

Your air conditioning system removes airborne contaminants from incoming air in order to protect sensitive equipment from damage that results when dust, dirt and other foreign matter builds up within. A secondary benefit of this system protection is cleaner air for your living areas. When contaminants are properly filtered out of the home’s air supply, living areas remain smelling fresh.

The first step in fighting dirty sock syndrome is regular air filter replacement. When homeowners neglect this important task, contaminants build up within the air conditioner, contributing to mold and mildew growth.

Today’s homeowners are increasingly concerned with their indoor air quality and the effects it has on a household’s health and comfort. For this reason, many in the Greater Lansing and Grand Rapids areas choose to utilize advanced air filtration methods such as whole-home media air cleaners and ultraviolet air purifiers to increase their control over indoor airborne contaminants. In the fight against dirty sock syndrome, UV air purifiers are especially helpful. Installed within cooling system ducts, this technology neutralizes mold spores, killing them and preventing regeneration.

Whether you rely on just a furnace filter or use advanced air filtration methods to keep your air conditioning system and your indoor air supply clean, these components are only helpful when they operate correctly. Dirty air filters and improperly installed air filtration devices are unable to do their job, which means mold and mildew continue to thrive unchecked.

Dirty Evaporator Coils

When warm air enters the cooling system from the home, it flows over the air conditioner’s evaporator coils where heat is extracted to lower air temperature. Without effective filtration methods in place, contaminants remain in the air supply and have the opportunity to settle on the evaporator coils during the cooling process. Combined with excess moisture, the dust and dirt left on the system’s coils create a breeding ground for mold and odors. The distinct, musty smell of mold is carried back into your home as cycling air moves over the coils during a cooling cycle.

Evaporator coils need to be cleaned for the elimination of dirt, debris, mold and mildew. Homeowners often turn to their trusted HVAC contractor to perform this essential maintenance service to protect the integrity and function of the system.

Clogged Condensate Drain

The cooling process extracts moisture from the home’s air supply, which means the air conditioner’s evaporator coil is normally exposed. The system’s drip pan and condensate drain lines function to remove this byproduct of cooling to control moisture levels within the evaporator coil cabinet, which deters mold growth.

However, if moisture collects in the drip pan and/or condensate drain line and does not properly exit the home, moisture surrounding the evaporator coils increases and creates the conditions mold needs to grow and remain. When your home’s air conditioning unit smells bad, the drip pan and condensate drain line need to be inspected as clogs can develop and block the removal of moisture from the air conditioner.

Extra Large Air Conditioner

Air conditioners that have a capacity too high for the home contribute to mold and mildew development. Oversized air conditioners complete cooling cycles too quickly; the air temperature is lowered to the setpoint before the system is able to dehumidify it. Moisture remains in the air as it travels throughout the cooling system and the home, which enables mold growth and odors in the home.

If Your Air Conditioner Smells Bad, Call A-1 Mechanical!

If your home’s air conditioner smells bad, odor isn’t the only problem you have. Mold and mildew are likely present, and will continue to be until their ideal environment is eliminated within your cooling equipment. There are other AC smells you should keep an eye out for, too. If your AC smells like rotten eggs, it could be an indication of a dead animal in the system or a natural gas leak. Either way, contact an HVAC company immediately.

A-1 Mechanical’s skilled air conditioner technicians are trained to remedy the indoor air quality and cooling system issues that cause mold and mildew to flourish within your equipment. If your air conditioner smells bad, contact us right away. Whether your home needs air conditioner maintenance, repair, replacement or indoor air quality services, we get the job done quickly to restore health, comfort and a clean scent to your household.

Why is My AC Running but Fan Not Spinning?

May 29th, 2020
Mechanical Fan

Summers in central Michigan are hot, and you need a reliable air conditioner to provide relief indoors when it’s too hot and humid to be outside.

Unfortunately, air conditioners can break down for a number of reasons – leaving you to sweat it out while you search for a reliable HVAC company to make the repair. One frustrating scenario the HVAC technicians at A-1 Mechanical Heating & Cooling have seen many times is when an air conditioner’s condenser fan stops spinning, even though the actual system is running.

At A-1 Mechanical, we’ve provided homeowners in Grand Rapids and Lansing with reliable and trustworthy HVAC service since 1983. Our NATE-certified technicians are expertly trained to make all types of air conditioning repairs, including repairing condenser fans that suddenly stop working. Give A-1 Mechanical a call today to schedule service.

Why Did My Air Conditioner’s Fan Stop Running?

If your air conditioning is running but there is no cool air and the fan isn’t spinning, it’s best to call an HVAC company to properly diagnose the issue. There are several possible reasons why your air conditioner’s fan isn’t working, including:

Issues with the capacitor

One of the most common reasons fans stop spinning is because of a dead capacitor. The AC’s capacitors are small, cylinder components that send energy signals to power the fan motor and the rest of the AC unit. Each air conditioning system has several capacitors, including the start capacitor, which sends signals to the motor, and the run capacitor, which keeps the motor running. Capacitors can go bad over time and need to be replaced.

Power issues

It can be as simple as a power issue. If the circuit breaker is tripped due to overheating, it will cause your AC to stop running. This can be fixed by flipping the switch at the circuit breaker.

Burnt-out motor

Another common reason fans stop working is a burnt out fan motor. When fan motors are overworked – coupled with a lack of maintenance – they can tend to go bad and burn out. AC fan motors are expensive to replace and may lead to system replacement.

Blocked air filter

A blocked air filter restricts air flow, which can cause ice to build up. This puts more stress on the air conditioner’s fan and can cause it to shut down. Change your HVAC filters regularly to ensure proper airflow.

A faulty belt

Older AC condensers use a belt. Over time, belts can slip off or break. This can be easily fixed by an HVAC technician, but it may be time to consider system replacement.

Issues with the contactor

The AC’s contactor switch, located inside your compressor unit, sends voltage to the condenser unit and fan so they will run. These switches can go bad over time, causing your fan to stop working properly. Contactors need to be replaced by an HVAC contractor.

Call A-1 Mechanical for AC Repair Services

If you’re having any issues with your air conditioner, including a fan that stops working, contact A-1 Mechanical Heating & Cooling for expert air conditioning repair. We repair all makes and models of air conditioners. Don’t let hot temperatures and high humidity be your enemy this summer. Call A-1 Mechanical today for the best AC repair service around!

Benefits of Zoned Heating and Air Conditioning

May 29th, 2020
Mechanical Zoned

Are some areas of your home too hot, while others are too cold? Finding the right temperature can be a juggling act. Things can get even more complicated when family members have different preferences regarding the right indoor temperature.

Worry no longer – A-1 Mechanical Heating & Cooling has the solution that will make everyone in your family happy! A zoned heating and cooling system works by separating the rooms in your home into individual zones to provide the perfect level of heating and cooling to everyone.

The NATE-certified technicians at A-1 Mechanical are Lansing, Grands Rapids and all of central Michigan’s leaders in HVAC repair, maintenance and installation. Contact A-1 Mechanical today to learn how a zoning system can improve home comfort.

How a Zoned HVAC System Works

Imagine a normal winter’s day. It’s bitterly cold outside, and you’ve set the thermostat to 68 degrees. However, a north-facing room with inefficient windows might be 64 degrees, while a south-facing bedroom on the second floor – where heat rises – may be a balmy 72 degrees. A zoning system can fix this problem.

A zoning system divides a house into two or more distinct temperature zones and are controlled by separate thermostats. This opens up the door for multiple options when it comes to heating and cooling. You can:

  • Keep rooms that are rarely used at a lower temperature in the winter and a higher temperature in the summer compared to the rest of the house
  • Keep your bedroom warmer in the winter and your guest room cooler when it’s not being used

The options are endless. To control the various flow of conditioned air into separate zones, motorized dampers are installed in the ducts. The dampers, which are able to open and close, receive signals from the independent thermostats in regards to what temperature the room needs to be heated or cooled. When a room reaches the desired temperature, the dampers are closed. When all of the rooms in a home are at the desired temperature, your home’s furnace or air conditioning system cycles off.

Benefits of a Zoned HVAC Systems

There are so many benefits to adding a zoned HVAC system to your Grand Rapids or Lansing home. Just a few of the them include:

Increased energy efficiency

Because you’re not constantly adjusting the thermostat to keep the house at just the right temperature, you’ll save money on your monthly energy bill. Rooms that are rarely used can be left cooler in the winter and warmer in the summer months. A zoned HVAC system can increase energy savings by as much as 30 percent.

Convenience

If you enjoy all the conveniences that come with modern technology, then you’ll love your zoned HVAC system. Each thermostat comes with its own remote that can be adjusted from anywhere in the house. That’s good news if you’re watching a movie or game and don’t want to get up.

Extended service life

With a zoned system, you won’t end up using your HVAC system as often as a conventional system that runs more frequently because it’s warming or cooling the entire home at the same temperature. This limits wear and tear on the system and leads to an extended service life.

Increased comfort

Everyone in the family will be happy because they can control the temperature setting to one that fits their individual comfort level.

Contact A-1 Mechanical about Installing a Zoned HVAC System

We’ve been serving homeowners in central Michigan with superior HVAC maintenance, repair and installation services since 1983. It’s no wonder we’re the most trusted HVAC company in the Grands Rapids and Lansing areas.

How to Protect Your Outdoor AC Unit from Spring Storms

May 4th, 2020
Air Conditioning

Storms are common during the spring season, which can put your outdoor air conditioning unit at risk for damage. Don’t risk an interruption in operation and comfort as you wait for repairs. A-1 Mechanical shares how you can protect your outdoor AC unit from storms.

Protecting Your Air Conditioner from Falling Debris

Be proactive as much as possible prior to storms. Remove dead branches from trees and the ground around your property. Trim back branches that overhang the area to protect AC’s condenser unit from storms and powerful winds.

If high winds are expected, the outdoor unit can be covered with a tarp or sheet of plywood to protect its top from falling debris. Such a cover also offers protection for large hailstones. For elevated units, secure the condenser unit with hurricane straps.

To protect the air conditioner from storms and debris that blow into its sides, try building a structure around it for protection. Such a structure keeps leaves and other debris from being blown into the interior of the unit, which can cause damage, clogs and performance issues. Any structure should be built at least 24 inches away from the unit on all sides. Shrubbery with strong root systems also provides natural protection for the unit.

It’s important to only do so if the air conditioner will not be in use during the storm. Remove the cover as soon as the storm passes, as you don’t want moisture to be trapped inside the unit for too long.

Protection from Flooding

There’s no need to cover an outdoor unit just because of rain – this equipment is designed for exposure to the elements. If a flood is expected, covers may be of some benefit, but only when they are thoroughly sealed.

Anytime an air conditioning unit is exposed to flood waters, even if you used a cover, it needs to be inspected by a professional before further use. Components may have been damaged while sitting in flood waters, which could make the system dangerous to operate without repairs.

During a Storm

Once a storm rolls in, cut power to protect the outdoor AC system from electrical surges caused by close lightning strikes. Doing so also prevents damage that could occur if falling debris becomes lodged within the unit’s interior.

To avoid discomfort during a power outage – or if you turn off power to protect your air conditioning unit from storms – pre-cool your home. Prior to the storm, lower your thermostat settings several degrees. Keep window coverings, doors and windows shut to help your home hold in more of its cooling while the storm carries on.

After a Storm

Before using your air conditioner again after a storm, always inspect it for potential damage. Do not leave the system shut down for too long, as doing so may cause mold and mildew development due to trapped moisture. If you are unsure if the unit has been damaged or if it has been flooded, call your HVAC system professional for inspection before use.

Air Conditioner Repairs from A-1 Mechanical

Despite your best efforts and the tips mentioned in this blog, it’s not always possible to prevent damage. If your air conditioner has been damaged, A-1 Mechanical performs fast repairs to quickly restore your system and return cool air to your home.

Common Questions About Ductless Mini Split Systems

May 4th, 2020
Ductless Mini Split

Ductless mini split HVAC systems are becoming more popular in homes throughout Grand Rapids thanks to their versatility, efficiency and other great benefits. However, many homeowners are still reluctant to consider this option for their homes because they’re simply not familiar with them. By answering some common ductless mini split questions, we hope it’s easier to see that this system type could be a great solution for your home.

How Does a Ductless Mini Split Work?

Most of us are used to central heating and cooling systems, which is why many people ask us how ductless mini splits work. A ductless system features two main components – indoor air handlers and an outdoor heat pump or air conditioner. Systems commonly feature multiple air handlers connected to an outdoor unit through a line set.

Ductless mini splits have dedicated air handlers installed in each area of the home, which create the ability for zoned comfort. Each one is controlled individually and independently. As such, efficiency can be improved by cutting waste, and comfort accounts for everyone’s preferences and the needs of a space without affecting temperatures across the home. Basements, garages or new home additions can use a single-zone mini split system if they want just that area to receive heating and air conditioning.

What Type of Homes Use Ductless Mini Splits?

Common questions about ductless mini split concern the versatility of the system. A ductless system is extremely versatile and can go where forced air systems often can’t due to space or cost considerations because of lacking ductwork.

Ductless systems are a great solution for scenarios such as:

  • Homes with no existing ductwork
  • Homes where there is not enough space to install a new duct system
  • Providing heating and cooling in a space not connected to the central air distribution system, like a recently finished attic or basement
  • In new additions where the cost of expanding the current central system to serve the area would be cost prohibitive
  • In areas of a home where supplemental heating and air conditioning is needed
  • In garages or outbuildings

How Efficient Are Ductless Systems?

Because there are no ducts involved with these systems, energy waste can be curbed as much as 30 percent compared to an average home with ducts. This is because most duct systems allow for significant heating and cooling loss through air leaks. Plus, the systems offer great energy efficiency ratings.

Is the Indoor Unit Big?

Interior aesthetics are important to homeowners, so questions about equipment are common. While there are a number of different interior air handler units, the units do have some size, but they’re not nearly as big as, say, a furnace sitting in your living room. Interior units come in a variety of finishes and are installed high on walls, so they can blend with your interiors. Some units are even set within the ceiling, so they really don’t detract from the look of the space at all.

How Much Do Ductless Systems Cost?

The cost of a ductless system depends on many things, such as how many indoor units need to be supported. The cost to install a ductless system across an entire home typically is far more than simply upgrading the central units if a home is already equipped with central HVAC. However, their efficiency cuts operating costs, generating savings over time.
