You can expect your AC unit to last for years easily. However, just because new units can last for over a decade, it doesn’t mean that this is automatic! Your unit may only last a few years if not properly maintained. When you consider the current summer season, it makes it even more vital to keep your system running properly.
We want to help you do that. That’s why we are going over some of the most common problems that we see air conditioners have and how you can rule out the easy solutions.
If your AC isn’t producing any airflow into your home, this is a major problem! After all, it makes no sense for your system to be creating cold air if it can’t move that air into your home. This is an obvious sign that something is wrong, but don’t panic. There may not be too much cause for alarm. We recommend checking on your electrical infrastructure first. While we often associate HVAC systems with our gas bill, they also need electricity. This is especially true for the fan motor inside almost every HVAC unit.
Make sure there is an adequate electrical supply to the unit by checking your fuse box or circuit breaker, whichever is applicable for you. If there is something wrong there, it has the potential to affect your HVAC unit. Fix that and see if the problem goes away.
If you still have a problem or your electricity never had anything wrong with it in the first place, you should give the unit an inspection. There may be a mechanical problem such as an issue with the fan belt. If there doesn’t seem to be anything wrong, you should take a look at the air filters near your vents. If these are clogged, it can cause airflow issues. This might only happen if you’ve really neglected to change your air filters for multiple months. Make sure you switch them out every month from here on out!
I’m Only Getting Cold Air from my Vents
This is a common problem. You walk past a vent and the air feels lukewarm. This may have an extremely easy solution. It’s exceedingly common and we don’t want you to feel embarrassed when you call a licensed pro when the solution is so easy.
This is all due to the fan setting on your thermostat. If it is set to auto, you are wasting energy and the fan will run regardless of whether the air conditioner is turned on or not. Just make sure you don’t have that setting on before you call an HVAC pro.
There are plenty of other reasons you could be getting cold air. It may be a good idea to call a pro if the problem persists. Just make sure you’ve ruled out the easy stuff first!
My AC is Loud and Noisey
An air conditioner is a mechanical machine. We don’t necessarily think about it, but there are a lot of moving parts in any HVAC system. This naturally means that noise will be a byproduct. However, if you are noticing strange noise from your AC, it’s likely that there is something up.
If you are hearing loud clanging noises, bumps, or screeching noises, this is a big problem. You’ll want a pro to take a look at it. Just be aware that some noises are perfectly normal for your AC to make!
My Air Conditioner Stinks
Sometimes, we have to use our nose to sniff out a problem with our HVAC units. Your HVAC unit can produce all kinds of smells, but the most common ones we see are rotten egg smell and a musty smell. These are signs of a dead animal or a mold problem, respectively.
Luckily, attentive homeowners can catch these problems before they get worse. You don’t want to wait until the problem is obvious!
