What Are the Most Common Reasons People Need Air Conditioning Repair Services?

Everything breaks down eventually. Whether it’s the moving parts of the AC you can see or something electrical deep within the unit has failed, every system will eventually need air conditioning repair services. Here are some of the most common problems that occur with air conditioners.

The Refrigerant Can Leak

When you’re interested in cooling the air, you won’t be surprised to know that it’s important that your refrigerant is at the right level. The most common problem that occurs is refrigerant leaking. Sometimes you’ll be able to see the problem, other times not. But when the refrigerant leaks and gets too low, your house will warm up even though the fan is running. At that point it’s time to call for AC service so that the tech can fix the leak and refill the refrigerant.

Another problem that can occur with refrigerants is if something went wrong during your last repair or maintenance. If previous HVAC service made a mistake and didn’t get the right amount in, too little refrigerant can reduce the efficiency of your system.

Compressor Problems

The compressor is a vital part of your air conditioner, and if it’s not working then you’re not going to get any cool air. The compressor’s job is to compress the refrigerant into a gas, which moves it through heat-exchanger coils. The cool air blown across these coils is then pumped through your house…unless, of course, the compressor has something wrong with it.

Minor problems like a starter can be replaced without much cost or trouble, but bigger problems can occur with a compressor. Either one can be handled by an experienced HVAC technician.

Dirty Coils

Speaking of the compressor and the coils, the fact that the air conditioning unit is outdoors means that it’s going to be exposed to more dust than any other appliance you own. Not only is it being pelted with dust that blows by, but the fan itself is creating currents of air that stir up nearby dust and give it more chances to get on your coils.

Why are dirty coils such a problem? Dirty coils cause the compressor to do more work to achieve the same result, which means it’s working harder and therefore putting more pressure on the system. While dirty coils won’t directly cause your AC to fail, they could lead to a problem down the line.

Broken Fan

The most noticeable part of the air conditioning unit is the fan. After all, when the fan is running, you know the air conditioner is on. You can hear it from many parts of the house and feel the warm air it’s blowing when you walk past the external unit.

The fan’s main goal is to take the warm air from the house and move it outdoors. If the fan isn’t working, the air conditioner has to work exponentially harder to cool the air in your home, which could put undue stress on the rest of the system. Make sure to call an AC service if your home is unusually warm and if you notice that the fan isn’t working.


Like most everything these days, products that used to just be electric have become electrical. There are more circuits and microchips in air conditioning units that are talking to each other and making decisions. While that makes them more convenient and efficient, it also means that there’s more that can go wrong.

Whether it’s because they’ve worn out or an electric surge damaged them, the electronics are crucial to your AC unit running properly. Failure in these systems can lead to units that don’t turn on, won’t turn off, or don’t keep the unit on for the proper amount of time for cooling to occur.

Something could be wrong inside

So your AC isn’t working. Most people will immediately think that there’s something wrong with the outdoor unit, but that’s certainly not always the case. The part of the air conditioner that’s outside is only part of what cools your home. It could be that something is wrong with other parts of your HVAC system.

It’s also possible that there’s something wrong with the wall thermostat. It could be that the thermostat has reached the end of its life, or maybe it simply got bumped without you knowing it. We’ll be sure to investigate the thermostat if it appears that everything is fine with the rest of the system.
