How fast can a technician reach Duarte?
Typical arrival for Duarte and nearby communities such as Dublin, Drytown, Ducor, Doyle, Dulzura, Downieville 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 Duarte cost?
Common repairs in Duarte 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 Duarte. 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 Duarte. 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 Duarte year-round. If you smell gas, leave the house first, call your gas utility, then call us.
Do you repair heat pumps in Duarte?
Yes. Heat pump repair in Duarte 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 Duarte?
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 Duarte?
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 Duarte.
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 Duarte?
All major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, Amana, Daikin, Mitsubishi, Fujitsu, Payne, Ruud, Heil, Tempstar and Coleman.
