Residential AC Repair
Roxly diagnoses and repairs AC problems for homes throughout the Charlotte metro area, with findings and an estimate reviewed with you before any work begins.
Common AC problems
- AC running but not cooling the house
- Warm air blowing from the vents
- The system short-cycling — on and off every few minutes
- Ice or frost forming on the indoor coil or refrigerant lines
- Weak airflow from the supply vents
- A musty smell when the AC runs
- The outdoor unit running constantly without cycling off
- Higher-than-normal humidity indoors while the AC runs
What's usually behind it
Most AC repairs come down to the capacitor, contactor, blower motor, condenser fan motor, or a low refrigerant charge in the sealed system — all serviceable components on an already-installed system.
Repair, not replace
A capacitor, contactor, or fan motor repair is a fraction of the cost of a new system, and most AC failures are exactly that — a single failed part, not the whole unit. Service availability may vary by location, equipment type, brand, technician availability, licensing requirements, and the scope of the requested work. Contact Roxly Appliance & Refrigeration Repair to confirm service availability for your address and equipment.
Safe checks before you call
- Check that the thermostat is set to Cool and a few degrees below room temperature.
- Replace the air filter if it's visibly dirty — a clogged filter is a common cause of weak airflow and icing.
- Confirm the outdoor breaker hasn't tripped and the outdoor unit isn't buried in leaves or debris.
Beyond these basics, leave refrigerant, gas, and internal electrical components to a technician.
Frequently asked questions
Why is my AC running but not cooling?
This usually points to a failed capacitor, a dirty condenser coil restricting heat rejection, a low refrigerant charge from a slow leak, or a blower motor that isn't moving air. A technician tests each in turn to isolate the cause.
Is a frozen AC coil serious?
Yes — running the system with a frozen coil can damage the compressor. Turn the system to Off (not just stop cooling) and let it thaw fully before your appointment.
Do you install new AC systems?
No — Roxly performs residential AC repair and maintenance on already-installed systems, not new system installation or full replacement.
Why does my AC short-cycle?
Short-cycling is often a bad capacitor, a dirty air filter restricting airflow, a refrigerant issue, or a thermostat problem. It puts extra wear on the compressor, so it's worth addressing quickly.
