The Problem
Heating Problems Don't Wait — Neither Should You
A broken heater is more than an inconvenience. It’s restless nights, frozen pipes, and a house that nobody wants to come home to. And in Los Angeles, where most homes aren’t built for sustained cold, even a few days without heat can cause real problems.
Whether your furnace won’t ignite, your heat pump is blowing cold air, or your wall heater smells like something’s burning — the fix starts with a call to the right team.

Heating Repair — Common Questions
What homeowners ask when their heater isn’t working or heating unevenly.
Why is my heater blowing cold air?
The most common causes are a faulty ignitor, a tripped high-limit switch, or a thermostat issue. If it’s a heat pump, it may be stuck in cooling mode due to a reversing valve problem. A technician can diagnose the specific cause in one visit.
How much does heating repair cost in Los Angeles?
It depends on the issue. A thermostat replacement is a different job than a heat exchanger repair. We provide a flat-rate quote after diagnosis so you know the exact cost before we start. No hourly billing surprises.
Should I repair or replace my heater?
Do you repair all heating system brands?
Yes. We service Carrier, Lennox, Trane, Rheem, Goodman, York, Daikin, Mitsubishi, and every other major manufacturer. Our trucks carry parts for the most common models.
How quickly can you get here?
For standard repairs, we typically schedule within 24 hours. For emergencies — no heat, gas smell, or safety concerns — we dispatch 24/7 with priority response.
Is there a diagnostic fee?
Yes, there’s a diagnostic fee that covers the visit and full system evaluation. If you proceed with the repair, we apply the diagnostic fee toward the total cost.
