For a homeowner, there’s a neverending to-do list. Every time you try to plan ahead, something else comes up that you didn’t expect and derails your plans. One thing you can do to make things a little easier and make it possible to set realistic expectations is to know how long various things in your home are likely to last.
Depending on the materials, a home’s roof might last somewhere near twenty years. A good hardwood floor can last a century. But we’re actually here to talk about your heating system. How long does a furnace last? How can you tell when it’s time for furnace replacement in Okemos, MI? Here’s the scoop.
Varying Estimates
Not all furnaces are the same. The biggest difference has to do with the energy source that the furnace uses. A gas-burning system has a shorter lifespan, ideally around fifteen years. An electric furnace will last longer, more like 15 years. Why is there such a difference?
When gas is combusted, it creates heat, of course. But it also creates exhaust, the combustion gasses that need to be safely vented out of your home. And because there’s water vapor in that exhaust, there’s going to be condensation. And it’s not just water, unfortunately, because there are acids in that exhaust. The condensation’s pH is closer to that of cola, which is corrosive enough that gas furnaces rust more quickly than electric ones.
Maximizing Lifespans
No matter what kind of furnace you have, you can take steps to maximize the lifespan of the system. In fact, when these system life expectancies are estimated, they’re based on furnaces that receive top-notch regular care. Without that, your furnace might only last half as long, leaving you looking for a replacement in 7-8 years instead of 10-15.
Critical care for a furnace has two parts. One is done annually: professional maintenance by a qualified HVAC technician who will clean, lubricate, inspect, and test every part of the furnace. The other is done more regularly, generally once a month when the furnace is being used daily: changing the air filter. This is a job you can do yourself. If you’re not sure how, consult your owner’s manual or call us with questions.
Signs of a Furnace in Need of Replacement
Many furnace issues can be easily repaired, so if your system is making a funny noise or your heat isn’t circulating as well as it used to, a technician can fix it immediately. However, as your furnace reaches the end of its expected lifetime, it may not be worth repairing it if the work will be costly.
If repair needs arise at least once a year, if regular maintenance doesn’t keep it working effectively and efficiently, and you’re left chilly and paying increasing energy bills, start thinking about a replacement. We’d be honored to help you find the new system that will keep you cozy for many years to come!
