Common AC problems we fix
Refrigerant leaks: the unit runs but can’t make cold air.
Broken fans: a failed indoor or outdoor fan means warm or weak airflow.
Frozen coils: ice on the lines or coil, often from low refrigerant or poor airflow.
Mold and musty smells: common in units that sat unused over winter.
Thermostat issues: temperatures swing or the AC won’t turn on.
Strange noises: hissing, banging or grinding.
Refrigerant leak repair
Refrigerant is what lets your AC make cold air. When it runs low:
- Cooling gets weak and the system struggles to reach the set temperature
- Ice can form on the refrigerant lines
- The unit works harder, wastes energy and can overheat
Evaporator coil service
The evaporator coil pulls heat out of your home’s air. A dirty or damaged coil means higher bills, poorer air quality and a shorter system life.
- Signs of coil trouble: the AC cycles on and off at random, makes hissing or banging sounds, or blows warm air.
- What we do: clean, repair or replace the coil on all brands and types.
Repair or replace?
If your AC is over 10 years old, needs repairs every season or uses an older refrigerant, replacement may save more over time. We’ll give you honest options. See AC Replacement.
