Common AC Problems We Repair in Tyrone, GA

When your air conditioner isn’t cooling properly, several issues could be to blame. At John’s Heating, Cooling, and Appliance Repair, we diagnose and fix the most common AC problems for homeowners and businesses in Tyrone and surrounding areas:

🔧 Refrigerant Leaks

Your AC needs the right amount of refrigerant to cool your home effectively. Leaks in the refrigerant line can lead to weak cooling, frozen coils, and higher energy bills. We detect and repair refrigerant leaks fast to get your system back to peak performance.

🧼 Clogged Air Filters

Dust, pollen, and debris can clog your air filter, restricting airflow and making your AC unit work harder than it should. Regular filter replacement is critical to system efficiency—and something we check during every service call.

⚠️ Faulty Compressors

The compressor is the heart of your AC system. If it fails, your unit can’t cool properly—or at all. Our trained technicians can quickly determine if your compressor needs repair or replacement.

❄️ Frozen Evaporator Coils

Frozen coils are often a sign of low refrigerant, airflow problems, or dirty filters. We’ll defrost the coils, find the root cause, and make sure your system stays cool and efficient.

🕹️ Malfunctioning Thermostats

If your thermostat isn’t reading the temperature correctly, your AC may short-cycle, run constantly, or fail to cool the home at all. We repair and replace faulty thermostats to ensure accurate temperature control.

⚡ Electrical Issues

Tripped breakers, faulty wiring, or blown fuses can prevent your AC from running. We inspect your electrical connections and safely repair any issues to restore operation.

🧽 Dirty Condenser Coils

When your outdoor condenser coils get clogged with dirt or leaves, your system becomes inefficient and may overheat. We clean the coils thoroughly during AC tune-ups and service visits to maintain optimal performance.
