Home Warranty: Common Causes of HVAC Failure
It’s a hot day. And though you’re a smart energy consumer and don’t leave your A/C going while you’re out of the house, your programmable thermostat kicks on just before you’re due to arrive home from work so the house is nice and cooled down. You can’t wait to walk through that door to your cool, quiet home, grab a glass of iced tea, and chill out on the sofa before you start dinner.
You walk through the door and that’s when it hits you – the wave of hot humid air and a sneaking suspicion that something is wrong with your air conditioning.
In some of the hottest months of the year, the smallest failures can cause the biggest catastrophes. And when something goes wrong, it can cost you…big. So when your Central A/C is on the fritz, here are a few things to check before you call someone for repairs.
A frozen condenser coil. Frozen coils can be caused by a variety of things. When filters and ducts are dirty, this can cause airflow blockage, which in turn causes coils to freeze. You can check for a frozen coil simply by visibly inspecting it for frost on or around it. If you see that it is frozen, you can follow some relatively simple do-it-yourself repair instructions.
A faulty circuit breaker or fuse. If your HVAC won’t function at all, it could be a tripped circuit breaker. The breaker provides the flow of electricity to the unite, and sometimes, a simple reset is all that’s needed. If resetting the breaker solves the problem, the tripped breaker could have been a fluke. But if the breaker trips again, it’s best to contact a professional electrician.
A refrigerant leak. Condenser units in your system require a refrigerant to cool the air for your home. When there isn’t enough refrigerant in the system, the air conditioner won’t function correctly, forcing the condenser to work much harder than it’s meant to, which can create to many additional issues. If you find a refrigerant leak, it’s best to call a contractor to service it. Depending on the severity of the cause, it could warrant full replacement of your HVAC unit.
Not having annual maintenance done. This should go without saying, but you should prioritize the annual maintenance of your HVAC system. Not only can ignoring it negate the warranty that comes with your system, it can cause your system to age much quicker. Plenty of companies offer annual maintenance packages.
A broken thermostat. Your HVAC malfunction may not actually be related to the HVAC unit at all. It could be your thermostat. Fortunately, this is one of the simplest and least expensive repairs you can make to your HVAC system. However, it’s not usually blatantly obvious, so you’ll want to have a professional come in to evaluate.
