24 Hour HVAC Repair — Emergency Service in the Antelope Valley
Emergency AC and heating dispatch when the temperature can't wait
24 hour HVAC repair means emergency dispatch outside normal business hours when a failure is a health or property risk — no cooling during a 105°F Antelope Valley heat wave, no heat on a freezing night, a burning smell, water pouring from an indoor unit, or a breaker that trips repeatedly. DC Air and Heating answers emergency calls at (661) 310-3340 with a $189 after-hours dispatch fee that covers the visit and diagnosis; the repair itself is quoted flat-rate before work starts, typically $185 to $895. Standard hours are 7 AM to 8 PM, seven days a week, and most Lancaster, Palmdale and Quartz Hill emergencies are reached within two hours.

Frequently Asked Questions
Do you offer 24 hour HVAC repair?
Yes. Our published hours are 7 AM to 8 PM daily, and we take emergency calls outside those hours at (661) 310-3340 with a $189 after-hours dispatch fee applied to the visit.
How much does emergency HVAC repair cost?
The after-hours dispatch fee is $189. The repair itself is quoted flat-rate before work begins and generally runs $185 to $895 — the same parts pricing as a daytime call, no surge on labor.
How fast will a technician arrive?
Two hours is typical for Lancaster, Palmdale, Quartz Hill and Rosamond. Santa Clarita, Acton, Mojave and outlying Kern County areas run two to four hours depending on time of night.
What counts as an HVAC emergency?
No cooling above 100°F with vulnerable occupants, no heat in freezing weather, gas odor, a carbon monoxide alarm, water actively damaging the home, or a repeatedly tripping breaker. A rattle or a warm room is a next-day call.
Should I keep running the system until you arrive?
No. Shut it off at the thermostat and the breaker. Running a system that is short on refrigerant, overheating, or drawing high amps turns a $300 repair into a compressor or board replacement.
Do you charge extra on weekends or holidays?
Weekends and holidays inside 7 AM to 8 PM are billed at standard rates. Only calls outside those hours carry the $189 after-hours dispatch fee.
