First Choice Heating & Air - North Charleston's Top-Rated HVAC Services

Yes, that's a very common problem here, especially during our hot, humid summers. The capacitor is like a battery that helps your AC's motor start and run. The strain of constant operation can cause it to fail. If your AC's fan isn't spinning or you hear a humming sound, a faulty capacitor is often the culprit. Our technicians carry a wide range of capacitors and can typically diagnose and replace yours the same day to restore your cooling.

This is frequently caused by a problem with the reversing valve, a key component that switches your system between heating and cooling modes. Mineral deposits, electrical issues, or mechanical wear can cause it to stick. Since our mild winters mean heat pumps cycle frequently, this part is under more stress. We can test the valve's operation, clear any obstructions if possible, or replace it to restore your system's full functionality for year-round comfort.

Given our climate, the two most critical tasks are cleaning the outdoor condenser coil and checking electrical components. Our salty, humid air can cause coils to corrode and reduce efficiency, while the constant summer operation strains capacitors and contactors. Our preventative maintenance service focuses on these vulnerable areas. We clean the coil, inspect and tighten all electrical connections, and test components like capacitors before they fail, helping you avoid the most common breakdowns we see in the area.
