How fast can a technician reach Fairfax?
Typical arrival for Fairfax and nearby communities such as Fairfield, Fair Oaks, Fall River Mills, Exeter, Fallbrook, Eureka is 2 to 4 hours for emergencies, and a same-day or next-day window for standard AC service and heating repair.
How much does AC repair in Fairfax cost?
Common repairs in Fairfax such as a capacitor, contactor, ignitor, flame sensor or thermostat usually run $150 to $450 installed. Blower motors, evaporator coils and AC compressor repair cost more. You approve a flat-rate price before we start.
My AC is not blowing cold air in Fairfax. What should I check first?
Check three things: the air filter, since a clogged filter chokes airflow; the outdoor unit, clearing debris and confirming the fan spins; and the breaker. If the indoor coil is iced over, set the system to FAN ONLY for one to two hours to thaw, then call us, because ice means low refrigerant or restricted airflow.
I have no heat in Fairfax. Is that an emergency?
If indoor temperatures are falling below the mid 50s Fahrenheit, or there are infants, seniors or anyone with a medical condition in the home, treat it as an emergency. We run 24 hour heating repair in Fairfax year-round. If you smell gas, leave the house first, call your gas utility, then call us.
Do you repair heat pumps in Fairfax?
Yes. Heat pump repair in Fairfax covers reversing valves, defrost boards, low charge, auxiliary heat strips, inverter mini-splits and cold-climate heat pumps.
Why is my furnace short cycling in Fairfax?
The most common causes are a dirty filter, a failing flame sensor, a blocked flue or a limit switch tripping from overheating. Short cycling wastes energy and can crack a heat exchanger, so it should be diagnosed quickly.
Do you offer AC tune-ups and furnace tune-ups in Fairfax?
Yes. Seasonal maintenance is the cheapest HVAC you will ever buy. An AC tune-up in spring and a furnace tune-up in fall prevents the majority of emergency breakdowns we see in Fairfax.
Are you licensed and insured?
Yes. Licensed, insured, EPA 608 certified and background-checked, with permits pulled where required.
Which brands do you service in Fairfax?
All major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, Amana, Daikin, Mitsubishi, Fujitsu, Payne, Ruud, Heil, Tempstar and Coleman.
