Emergency Furnace Repair — No Heat Service, Same Night
No-heat dispatch for gas furnaces, heat pumps and packaged units
Emergency furnace repair is warranted when there is no heat and the overnight low is near or below freezing, when a carbon monoxide detector sounds, when you smell gas or a burning odor, or when the furnace trips its breaker repeatedly. DC Air and Heating dispatches emergency furnace repair across the Antelope Valley at (661) 310-3340; the after-hours fee is $189 and the repair is quoted flat-rate before work starts, typically $185 to $895. Before we arrive, shut the furnace off at the thermostat, leave the gas valve alone if you smell gas and get outside, and replace a visibly clogged filter — an overheated furnace locking out on its high limit is one of the most common no-heat calls we run.

Frequently Asked Questions
Do you do emergency furnace repair at night?
Yes. Call (661) 310-3340 any hour. Standard service runs 7 AM to 8 PM daily; outside those hours a $189 emergency dispatch fee applies to the visit and diagnosis.
How much does emergency furnace repair cost?
$189 dispatch after hours plus the flat-rate repair, which is usually $185 to $895. Flame sensor and ignitor jobs are at the low end; blower motors and control boards at the high end.
What should I do while waiting for emergency furnace repair?
Turn the thermostat to OFF, check that the filter isn't clogged, and use only safe supplemental heat — never an oven or an unvented gas heater. If you smell gas or a CO alarm sounds, leave the house first and call from outside.
Why did my furnace stop working in the middle of the night?
The most common overnight failures are a flame sensor that has oxidized enough to lose signal, a hot-surface ignitor that cracked on a cold start, and a high-limit lockout caused by a clogged filter restricting airflow.
Is a cracked heat exchanger repairable?
No — it must be replaced, and on most furnaces over 12 years old the exchanger cost approaches a new furnace. We red-tag the unit for safety and quote both options the same visit.
Do you service heat pumps on emergency no-heat calls?
Yes. Heat pump no-heat calls are usually a failed defrost board, a stuck reversing valve, or auxiliary heat strips that have burned out — all handled on emergency dispatch.
