Start With the Easiest Fixes

When investigating what is wrong with your AC unit at your Gainesville home, it’s best to start with the easiest fixes first. These include:

  • Thermostat. Since the thermostat is the brain of your air conditioning system, it makes sense to start there. Check to be sure the settings are correct. One simple solution we often find here at our air conditioning company is ensuring the switch is set to “cool” and not “heat.” This is a common occurrence right around the time winter is ending. Another common issue is your thermostat battery may have died. This would cause your AC unit to not function properly, either.
  • Air filter. Many people underestimate the importance of changing out the air filter on their AC unit. If the air filter gets too clogged, air won’t flow through properly. This can result in huge inefficiencies and a lack of cooled air in your home, leading to a feeling of your room being too hot. You should be checking and changing your air filter on a regular basis anyway.
  • Air vents. The air vents of the air conditioning system for your Gainesville home are where the treated air flows from. However, if they are clogged with a lot of dirt and debris, air flow will be impacted, resulting in a hotter home than you desire. Plus, critters love to invade your air ducts, so a good check is recommended, too.

Electrical System

There are a lot of wires in your air conditioning system that all need to function properly in order for your AC unit to cool your home as expected. The first electrical issue you should check is if the breaker is tripped. This is a common occurrence, especially during high-demand and peak-energy times. If the breaker is tripped, you simply flip it on again. However, if you notice other wires that don’t quite look right, you’ll probably need to call your trusted HVAC technician from Buckhalter Heating & Air Conditioning for a more in-depth analysis.

Check Your Air Conditioning Condenser

Another common issue our air conditioning repair technicians see here at Buckhalter Heating & Air Conditioning is a clogged or blocked condenser. Your AC condenser is the outdoor part of your AC system. It is responsible for taking hot air and making it cool. However, your air conditioning condenser can gather a lot of dirt, dust, and grime over time that can prevent this process from happening effectively. It can also cause your AC unit to overheat, causing even more damage. Be sure to check your outside AC unit regularly and clear away any dirt and debris promptly.

Check Your Air Conditioning Evaporator

Your AC unit evaporator works in conjunction with your AC condenser. The evaporator coil is inside and it receives the refrigerant and then turns it into gas. The outdoor condenser takes this gas, pressurizes it, and then turns it back into liquid. The evaporator coil then releases this heat via the exhaust fan and pushes the refrigerant back inside the handler to start the cooling process all over again. A frequent problem with the condenser is it can become clogged with pet hair, dust, and more; this can cause other condenser issues, too. These types of problems are best handled by an experienced HVAC technician, so call us to set up a convenient time today!
