HVAC Services: Diagnosing an AC that Won’t Cool

Woman feeling hot and trying to refresh in summertime heatWhen it comes to accurately pinpointing what exactly is wrong with a malfunctioning air conditioning system, you need the assistance of a Valparaiso, FL HVAC professional. And in our area, we know how vital it is that the problem is taken care of right away. Hopefully, you already had maintenance done on your system and don’t have to deal with this problem at all.

But chances are, if you’re reading this, you may already be facing it. So, although our next piece of advice is going to be “give our professionals a call to schedule service,” we can certainly give you an idea of what to expect when we come to diagnose what’s wrong with your cooling system.

First, Check the Thermostat

The good news is that your air conditioner problem might not be a problem with the system at all! Perhaps someone in your family accidentally turned the thermostat up a few degrees (or, on purpose, if they have a different comfort level than you). Or it could be that the air conditioner got switched to “fan only” mode, in which case it will only circulate air rather than cooling it as well.

Change the Air Filter if Needed

There’s a common belief that the air filter that comes standard with an HVAC system is there to protect your indoor air quality. It’s actually there to protect the inside components of your air conditioner, however. And if it gets too clogged up, it won’t allow the cool air to flow through to your living spaces.

It May be Your Evaporator Coil

The problem might be a frozen evaporator coil. This component is the part of your air conditioner where heat is drawn from the air and cooled. Ice might seem like a normal part of this process, but trust us when we say it’s not. The ice actually blocks the coil from absorbing heat. This ice might be the result of low refrigerant due to leaks, or too much dirt and grime on the coil.

Failed Compressor Motors

The fan in your air conditioner’s air handler might be working just fine, sending out air through your ventilation system. However, if the outdoor compressor isn’t functioning due to failed capacitors or a failed motor, then you won’t receive any cooling at all.

Our technicians will check on the compressor and see if the problem can be repaired. If the compressor has burnt out, however, it will need to be replaced, and this usually means the whole air conditioner needs to be replaced.

Broken Condenser Fan

The outdoor unit of your air conditioner contains a fan that’s responsible for drawing outdoor air into the system and across the condenser coil, so heat can be released to the outside. If the fan is not working, then heat can’t be released. As a result, the refrigerant won’t cool down, and the air conditioner can’t do its job. Be sure to call in a pro if you suspect a problem with the fan.
