Quality AC Repair in Keystone Heights, FL 

Request Service

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 braved the 102 degree heat, wasps who decided to make a nest hiding in my AC and the metal on the unit was hot! Jamar remained positive, friendly and happy to be doing my regular servicing of my AC. Southern Air knows how to pick their technicians. I have had remarkable service for over 7 years with Southern Air. Cannot recommend them any higher. I love having their annual service plan and you can budget with monthly payments. A++++++++
