Common AC Problems We Repair
No cooling or warm air, often caused by low refrigerant, a failed capacitor, a faulty contactor, or a compressor problem.
Weak airflow, which can indicate a clogged filter, a failing blower motor, or ductwork restrictions.
Ice on the evaporator coil, usually linked to low refrigerant or restricted airflow.
Water leaks inside, often from a clogged condensate drain. See our AC leaking water inside guide.
Strange noises such as rattling, buzzing, or grinding, which can indicate loose parts or a failing component.
When to Call for Professional AC Repair
Call for service if the AC is not cooling, is short-cycling, is leaking water, or is making unusual noises during a heat advisory.
If cooling fails during extreme heat, request emergency HVAC service or call our dispatch line.
