Hopefully, it’s just a tripped circuit breaker or a blown fuse causing the problem if your air conditioner suddenly stops. However, it can potentially be something more serious and worrying.

Most homeowners can diagnose and fix many air conditioner issues themselves, although more serious problems will require you to call out a trained technician.

Several of the most common A/C issues can be addressed if you follow these handy and practical troubleshooting tips we put together for you.

Simply having annual maintenance carried out on your air conditioning unit can help to prevent many serious and potentially costly A/C problems. Contact AJ Perri through our website or talk to one of our helpful employees for more information on how our annual maintenance plan can help you and save you money.

1) Air Conditioner Won’t Turn On

Firstly, make sure the condenser is running by checking the outside unit. Your thermostat should be set properly and set to cool, and of course, the unit should be plugged in.

Lowering your thermostat by between 5 and 10 degrees often fixes this problem. It’s no secret that some thermostats are just trickier than others, according to John, our maintenance expert and you can often save money, time and stress by studying the owner’s manual.

Make sure a tripped circuit breaker or blown fuse isn’t causing the problem.

“You may have a problem with the compressor or motor if the coil is frozen or the unit won’t turn on,” says theĀ Corpus Christi air conditioning repair experts at AAA AC. A professional will need to come and fix it if that’s the case.

2) Air Conditioner Isn’t Cooling Properly

If your system isn’t cooling as it should, and you can switch the unit on and have the thermostat set correctly, a blocked or dirty air condenser may be to blame. To ensure efficient air circulation, remove any weeds, leaves or other debris that might be blocking the outside unit.

A dirty filter can restrict airflow to the evaporator coil, and checking that your filter is clean is your next step. Pulling out your filter and seeing if you can actually see through it is a simple yet effective test. You may need to change your filter more often if you run your air conditioner more often or you have pets in your home.

You’ll need to call a professional if your air conditioning unit still isn’t keeping your house cool; it’s likely an issue with the refrigerant or compressor.

3) Air Conditioner Isn’t Cooling Effectively

It’s possible your unit just isn’t large enough for your home if it’s switched on, set properly but still not keeping your home as cool as you would like.

A temperature difference of between 20 and 25 degrees between the indoor and outdoor temperature should be something that the average air conditioner is able to do. So if it’s 95 degrees outside, you should realistically expect your inside temperature to be around 75 degrees, but not 68 degrees. As a general rule, on an average summer day, your air conditioning system should be keeping you comfortably cool, and if so, it’s a sign that everything is working as it should do.

If your air conditioner just can’t keep up and it’s a normal summer day and not especially hot, the evaporator coil being frozen may be the problem, or the charge may not be sufficient to cope. You should always call a professional and turn your A/C system off if you look outside and see icing on the unit.
