Not every AC problem is obvious. Sometimes your unit keeps running but your home never feels cool. Other times it stops working completely on the hottest day of the year. Either way, waiting to call rarely makes things better. We service every major AC brand, with specialized expertise on the Carrier and Lennox systems we install as an authorized dealer.
Calling at the first sign of trouble usually means a cheaper repair. Ignoring the problem often turns a simple fix into a compressor replacement.
Most AC failures come down to a handful of issues. Here is what we see most often in Atlanta homes.
When your coils freeze, your AC stops cooling and eventually stops running. Low refrigerant or blocked airflow is usually the cause. Left alone, frozen coils can damage the compressor.
Capacitors give your AC the jolt of power it needs to start. They wear out over time, especially in hot climates. A failed capacitor often sounds like humming or clicking without the unit actually starting.
Low refrigerant does not mean your system used it up. It means there is a leak somewhere. We find the leak, repair it, and recharge the system with the right refrigerant for your unit.
Sometimes the AC itself is fine but the thermostat is not sending the right signal. We test, recalibrate, or replace thermostats as needed. We work with all major brands including Nest and ecobee smart thermostats.
The compressor is the heart of your AC. When it fails, you have a bigger decision to make: repair, replace the compressor, or replace the full unit. We walk you through the options honestly, based on the age and condition of your system.
Loose connections, burned-out contactors, and tripped breakers can all stop an AC cold. These are dangerous to DIY. Our techs are trained to diagnose and fix electrical faults safely.
A dirty outdoor coil or clogged filter can make your AC work three times harder than it should. We clean, clear, and check airflow on every service call.
