AC repair in Fort Mill, SC
When your air conditioner quits on a humid Fort Mill afternoon, you want a clear diagnosis and an honest fix. Kool Katz HVAC repairs central air conditioners and heat pumps across Fort Mill, Tega Cay, Indian Land, and Rock Hill.
Signs your AC needs repair
- Warm or barely cool air coming from the vents
- The outdoor unit hums, clicks, or won't start
- The system turns on and off every few minutes (short cycling)
- Ice on the copper lines or the indoor coil
- Water around the indoor unit or a ceiling stain under the attic unit
- The house feels cool but sticky, or the bill jumped with no change in use
Why ACs fail in Fort Mill
Our long, humid cooling season means a lot of run time. Starting components like capacitors and contactors wear out, fan motors overheat, and condenser coils clog with dirt, grass, and spring pollen. Condensate drains clog with algae in the heat and back up into pans and ceilings. Many of these problems give warning signs first, so call when something sounds or feels different instead of waiting for a full breakdown.
What to check before you call
- Make sure the thermostat is set to Cool and the set temperature is below the room temperature.
- Check the breaker for the indoor and outdoor units.
- Look at the air filter. If it's caked with dust, replace it.
- If you see ice, turn the system off so it can thaw.
Still not cooling? Call (803) 653-6339.

AC repair questions
Why is my AC blowing warm air?
Common causes include a failed capacitor or contactor, an outdoor fan or compressor that isn't running, low refrigerant from a leak, a very dirty coil, or a tripped breaker or safety switch. Check that the thermostat is set to cool and the breaker is on, then call us.
My indoor lines are covered in ice. What should I do?
Turn the system off and let it thaw, then switch the fan to On to speed things up. Ice usually points to an airflow problem, like a clogged filter or blocked return, or to low refrigerant. Running a frozen system can damage the compressor, so call us to find the cause.
