The summer months are in full swing which means this is the time you’re relying on your AC the most. The last thing you want to happen is for your AC unit to stop working! With AC units sometimes being so complex, issues are inevitable. Even the best air conditioners can run into problems. It’s not any fun waiting in temperatures above 90 degrees outside, so if your unit stops working for some reason, you’ll need a repair quickly. Here are the top 10 reasons why your AC might not be working.
Dead batteries in your thermostat
One of the smaller and easier fixes of a non-working air conditioning unit is that the batteries in your thermostat might be dead. Luckily, that means nothing is wrong with your air conditioner at all, and all you have to do is change the batteries! If you ever notice that the screen on your thermostat is blank and you’re not sure why- assume that the batteries are dead.
Circuit breaker trip
Another simple problem that requires an even simpler solution is if your circuit breaker was tripped. If you get a power surge in your home for any reason, it’s very possible that your AC circuit breaker could have been tripped, leading to a temporary stop of the system. While flipping the breaker back to “on” is an easy task, remember to always be cautious when dealing with electrical work.
Need a new filter
To add to the list of simple fixes, changing a dirty filter will be one of them. Changing a filter is a common thing to forget to do. It is recommended that you change your air filter at least every 60 days. It’s also smart to consider what type of air filter you should use depending on your location and how frequently you use your AC.
When your thermostat is set to “cool” but cool air isn’t blowing out, it could be that you have a dirty coil. If you don’t get your unit serviced regularly, both the coil for the indoor unit and the coil for the outdoor unit can get dirty.
Low refrigerant cooling
Another common reason your unit might not be working is the possibility of your coolant level being too low. The refrigerant is what cools the coils in the unit, so without proper levels, your home might not be able to cool off as much as you’d like it to. This is one of the jobs where you should call on a professional to refill your coolant and look at your unit to make sure there are no leaks.
It sounds kind of silly… but it’s a legitimate reason as to why you might think your AC isn’t working! If you’ve checked everything else you know to check and you’re still not feeling cool air, go back and check the vents. You could have closed them off a while ago for some reason and just forgot to open them back up. It’s not a big deal, and it’s very fixable!
Leaking Water Inside
A problem that can sometimes be found inside of your home is water leaks. This most likely means that your condensate drain line is clogged up, not allowing the water to properly flow through. If you want to fix this yourself, you can try using a wet/dry vacuum to unclog the line, but you can also call a professional to help with that as well.
Problems with the compressor
A little bit more on the serious side of AC unit problems is issues with the compressor. The compressor in your unit is what circulates and compresses the coolant through the unit. It could go hand in hand with the air ducts as well. If the air you desire in your home is not properly being circulated throughout the area, you can most likely chalk it up to problems with the compressor or air ducts.
Tripped float switch
The safety mechanism that is built into your AC unit is called the float switch. The purpose it serves is to shut off your unit when the drain pan gets too high, stopping it right before it overflows. If your drain is clogged and not draining properly, that might be the main reason your flip was tripped.
Damage to the different components
Lastly, a reason that your AC unit isn’t working may be a result of some sort of damage that is acquired. Maybe you have landscapers that got too close to a line. Perhaps a heavy ball was thrown into the unit, damaging something on the inside. The list of possibilities is endless!
