A quality air conditioning unit is an investment in your home. This is why it’s important you properly care for your unit in order to prevent expensive air conditioner repairs or premature air conditioning replacement in the future.


As we transition into warmer weather, people begin to seek comfort in their air conditioning unit to keep them cool during those warm, summer days. However, a common mistake individuals make is not removing the cover from their unit before turning on their air conditioner.

If you overlook this important step in preparing your air conditioner for the summer and turn your air conditioning unit on with the cover still on it, the unit will overheat quickly. This will often times be a very costly mistake if parts being ruined due to the overheating, or even worse, this could lead to needing to replace your entire a/c unit if the damage is too significant.


Inspecting your air conditioning unit filter every month can help make sure that your unit remains energy efficient. This is simple air conditioner maintenance that you can do by yourself. First, take note of any dirt or dust that has collected in the filter. If there is a significant amount, you may have to replace it with a new filter.

When buying your new air conditioner filter, make sure that you get the right filter type as well as a filter with the right dimensions. Different types of air conditioner filters include fiberglass, pleated, and media. When done properly, air conditioning unit filter replacement can help your unit run efficiently.


If leaves, dirt, dust, and other debris collect on your outdoor air conditioning unit, it could cause the appliance to lose energy efficiency. This is because the clogged air conditioner vents aren’t able to circulate air efficiently, causing the unit to work harder to produce the same cooling results.

Debris could also be covering your air conditioner coils. Dirty air conditioner coils create an insulating effect which makes it hard for the unit to disperse the heat from your home into the outdoor environment. When you’re in your backyard, make sure to do a cursory check around your air conditioning unit. You should especially keep an eye on your unit during the autumn months when leaves are falling and after the snow melts.


While many homeowners are already aware of the benefits of programmable thermostats or home automation systems, there are certain things to keep in mind. For example, if you set your thermostat too low, you may be decreasing the lifespan of your unit through overuse. Sometimes there will be days when it makes more sense to open a window to let in cool fresh air than to run your air conditioning unit.

If you travel frequently for your job, you might want to program your thermostat to a lower temperature for while you’re away from home. Not only will this help you save money, but your home will become more energy efficient. Just remember that you need to keep your home’s temperature at a minimum of 55 degrees Fahrenheit to prevent pipes from freezing.


If you are looking to extend the life of your air conditioning unit, it’s important that you schedule preventative air conditioner maintenance. While there are many preventative steps you can take by yourself to keep your air conditioner in working order (such as changing the air filter as needed) other issues will need to be resolved by cooling system technicians.

By setting up a regular maintenance plan with a licensed cooling system company, you will be able to catch minor air conditioner damage before your unit needs more expensive repairs. This can help save you money so you don’t end up being blindsided by an unexpected major air conditioner repair a few months from now.
