Quality AC Repair in Keystone Heights, FL 


The hot Florida summer is no time to find yourself with a broken-down air conditioning system in Keystone Heights or anywhere around the northeastern region of the Sunshine State. If you find yourself in need of air conditioning repair services, rely on the experts at Southern Air Heating & Cooling to provide expert AC repair in Keystone Heights, FL. 

How To Know When You Need Air Conditioner Repair

Several common signs indicate that your cooling system needs professional AC repair in Keystone Heights, FL.

Poor Performance

Malfunctioning compressors, refrigerant leaks, dirty or damaged coils, and other problems lead to poor cooling performance. If your system is taking longer than usual to blow cool air or is only blowing warm air, you should have your unit inspected. 

Excess Humidity

When your air conditioner is functioning correctly, it removes excess humidity and heat from your indoor air. If your indoor air has become stale or excessively moist, your evaporator coils may be having trouble expelling moisture before recirculating air into your living space.

Strange Sounds or Smells

Refrigerant leaks, mechanical problems, or overheating can cause unusual sounds and odors from your air conditioning unit. 

Short Cycling and Electrical Issues

If your thermostat is malfunctioning or there is an issue with electrical connections or circuit breakers, your system may short cycle — meaning it turns on and off frequently without significantly changing indoor temperature. 

Weak Airflow

If your airflow has become weak, irregular, or nonexistent, dirty filters or evaporator coils could be restricting air from properly circulating through your system. Fan motor malfunctions also affect airflow.

Spikes in Utility Bills

Any symptoms described above and other issues cause your cooling system to work much harder to produce cool air. Sometimes, the first evidence of trouble is a sudden and unexpected increase in energy consumption.

Annual Maintenance for Optimal Performance

The annual maintenance service provided by Southern Air Heating & Cooling includes thorough inspections, cleaning, and system tune-up to keep every component in your HVAC air conditioning system operating at peak efficiency. 

Regular professional maintenance is a crucial part of AC repair in Keystone Heights, FL. It extends the lifespan of your cooling system and saves you money on utility bills and repair expenses.

During our service visits, we: 

  • Inspect all components for proper function and wear and tear
  • Clean filters, coils, and critical parts
  • Lubricate moving parts
  • Check and top off refrigerant levels while checking for leaks
  • Test and calibrate the thermostat and electrical components

Jamar checked the air handler as it was making a strange noise. He said it most likely was doing that because the air filter was very dirty. I changed the filter last night & we could not hear it anymore. While he was here, he checked the system out & all was running ok!
Response from the owner:Louise, thanks for taking the time to share this. I’m glad Jamar was able to pinpoint the likely cause and that changing the filter solved the noise right away. We appreciate you choosing Southern Air, and it’s great to hear everything else checked out and is running well.

He was here for a couple of hours troubleshooting my AC as to why it wasn’t communicating with my Thermostat. He was on hold with the Lenex Technical Support and never got them to answer back. Another tech suggested a work around to test system and it worked. Got us a working unit until they could replace the wiring going to the electronics. Just a standard service call price.
Response from the owner:Richard we apologize for the inconvenience but appreciate your patience and understanding. We are diligently working with the manufacturer to get this resolved for you as soon as we can. Thank You!

    Southern Air has been great to work with; their techs are always on time, friendly, professional, and they explain things in an easy-to-understand way even if you don't know anything about how air conditioners work. Getting twice-yearly maintenance on my unit really gives me peace of mind that it's being kept up and if anything does go wrong I'll know about it before it gets too bad.

    We’ve had a great experience with Southern Air in Palatka, especially as members of their Comfort Club. It’s been a really great value for us because a technician comes out twice a year to check everything over and make sure our system is working well and staying on track.

    This most recent visit was with Dylan, and he was excellent—professional, thorough, and easy to talk to. He cleaned our vent and spent real time going through the system to make sure everything was running exactly as it should. You could tell he cared about doing the job right, not rushing through it.

    Highly recommend Southern Air, and if you’re considering the Comfort Club, it’s absolutely worth it.
    Response from the owner:Kristen, thank you for the kind review and for being part of our Comfort Club. I’m glad the twice-a-year checkups have been a good value for you, and that Dylan took the time to thoroughly go through your system, clean the vent, and make sure everything was running the way it should. We really appreciate the recommendation.
