We repair central air systems, ductless mini-splits and heat pumps of every major brand, and we quote the repair before we start.

- Ice is forming on the refrigerant lines or indoor coil
- Water is leaking from the air handler or through a ceiling
- A burning smell or loud grinding is coming from the unit
- The thermostat is blank or unresponsive
- Someone in the home is at risk in the heat
Emergency AC repairs we handle
Capacitors, contactors and fan motors
The most common heat-wave failures. Usually repaired on the first visit from van stock.
Refrigerant leaks and recharges
We find the leak with the proper tools, repair it, and recharge the system to specification rather than just topping it off.
Frozen coils and airflow problems
Blocked filters, failed blowers and low refrigerant that turn the coil into a block of ice.
Condensate leaks
Clogged drain lines and failed condensate pumps that flood closets and ceilings.
Electrical and control faults
Tripped breakers, failed control boards, thermostats and low-voltage wiring.
Compressor failures
Honest diagnosis. If the compressor is gone, we lay out repair versus replacement with real numbers and financing options.
