HVAC Troubleshooting: Why Your AC Unit is Not Cooling

The cooler winter months are over and our area is really starting to heat up. If you’ve lived in Pooler, GA for long, you know the heat is here to stay for at least the next six months. That’s why it is so distressing to realize that your AC unit is not cooling the way it should be. You can’t get through the summer without your home HVAC unit working hard to keep you comfortable! When you have a running compressor, but your air conditioning unit is not producing cool air, there are potentially a number of things that could be causing this problem. Let’s discuss the possible problem areas and solutions:

#1 Clean or Replace Your Filter
Your filter will be located in the air handler cabinet, and will be easily accessible from the door on the front. You’re supposed to be replacing your filter at least every three months, or when it’s too dirty to properly work. If it’s been longer than this, the filter is blocking the cool air from coming out and is the cause of your poor air flow. Thankfully, this is an easy solution! Some filters are designed to be cleaned and put back in while others can be thrown away and replaced with a new one.

#2 Check Your Electrical Wiring
Nearly all Pooler, GA HVAC repairs stem from electrical problems. You will want to examine all of the wiring within your unit, especially the wiring connected to an outlet. You may have tripped the breaker or a blown fuse. Electric problems are never a DIY fix, so it is time to bring in a HVAC technician.

#3 Check Your Ductwork
Your ductwork is there to deliver and distribute the cooled air your HVAC unit has worked so hard to produce. If your ductwork is cracked or lacks proper sealing, your nice, cool air may be dissipating inefficiently and not coming out the proper vents. The good news is that you still most likely have a healthy, well-functioning air conditioning system. The not-so-good news is that your ductwork needs some TLC, but it’s nothing a trained professional cannot handle.

#4 Check for Leaks
Think of refrigerant as the lifeblood of your HVAC system. It absorbs excess indoor heat and releases it outside. In order to do this job, it has to run this constant cycle. If it is not maintained on a regular basis, the unit will begin developing small leaks. Leaks may also simply be a result of old age. If left to leak out, this can severely inhibit the ability of your HVAC to function.

#5 Clean the HVAC Interior
Your HVAC unit may need a good cleaning! Cleaning out the condenser, evaporator, filters and coils may do the trick to get your unit running cool again. If these are dirty and clogged by debris, air flow within your unit may be restricted. This severely affects the efficiency of your unit, making your home feel too hot.
