A troubleshooting guide detailing some of the most common issues that you may come across with air conditioners.
Arlington, TX – Whenever your air conditioner is not cooling it can be cause for alarm. This is especially true if it is in the dead of summer. Whether your AC is not cooling or not working at all, you will obviously be looking for answers. This is where we come in.
There are many reasons why your AC may have problems. However, most of the time it is a simple reason. It could simply be a blown fuse, or the circuit breaker has tripped.
In this troubleshooting guide, we will go over the most common reasons why your air conditioning may not be cooling.
The Air Conditioner is not Cooling
In this scenario, your HVAC turns on and the thermostat is set correctly. However, for whatever reason, the AC is not distributing cool air. One of the most common culprits for this is a dirty, blocked, or iced-over air condenser.
The first thing you should do is inspect the outside unit and if needed clean it. Remove any dead leaves, weeds, and vegetation that are immediately surrounding the unit.
Next, inspect the air filter and ensure that it is clean. If not, replace it with a fresh air filter. If you have a hard time remembering to change the filter, then set a monthly reminder on your phone.
After performing these steps, check to see if the AC starts producing cool air. If not, and the filter was extremely filthy and clogged, there is a chance that the evaporator coil may be clogged. Your next step would be to contact a professional service company to perform maintenance on your AC system.
Air Conditioner Won’t Turn On
In the second scenario, the air conditioner does not turn on at all. The first thing you should do is check your breaker box and see if the circuit breaker has tripped. If instead, you have a fuse box inspect it to see if the fuse was blown. If this is the case with either, then just flip the breaker back on or replace the fuse. Wait a minute or two and then see if the AC will turn back on.
If the breaker box is not the problem, then go have a look at the thermostat to make sure it is set correctly. If so, then head outside and look and see if the outdoor condenser is running. Also, make sure that the system is plugged in.
If none of the above is the problem, then it could possibly be something wrong with the motor or compressor. You will need to reach out to a professional HVAC service company for repairs at this point.
Air Conditioner does not Cool Enough
In the last scenario, your AC turns on and it cools, but it just is not cooling enough. If this has always been the case, then you possibly have an HVAC unit that is not sized correctly.
A properly sized system will be able to maintain between 20 – 25 degrees difference between the outdoor and indoor temperatures.
If the AC has become less efficient at cooling over time, there is a chance you have a freon leak. Another possible problem could be a frozen evaporator coil. Inspect the outdoor unit and if you notice any icing, shut off the system and contact a service company.
