Heater repair in Los Angeles — diagnosed by engineers, not parts-changers.

When your heat goes out, you want a technician who finds the actual problem — not one who swaps a part, charges you, and hopes. HVAC in LA is led by a USC-trained mechanical engineer, and we diagnose every no-heat call methodically: gas pressure, ignition, airflow, electrical, and controls.

Common heating problems we fix

  • Furnace won't turn on — thermostat, igniter, control board, tripped safety, or power issue
  • No heat / blowing cold air — failed igniter, flame sensor, gas valve, or heat-pump reversing valve
  • Short-cycling — clogged filter, dirty flame sensor, overheating limit switch, oversized system
  • Loud bangs, rattles or squeals — delayed ignition, blower motor, or loose components
  • Weak airflow — clogged filter, failing blower, or duct issues
  • High heating bills — aging system, leaking ducts, or refrigerant charge off on a heat pump
"They diagnosed in 20 minutes what two other companies couldn't find in three visits. Fair price, no upsell." — Lindsay J. H. Brown, Brentwood
How it works

Our heater repair process

What to expect from first call to verified fix.

1

Free phone triage

Tell us the symptoms. We'll often narrow the issue before dispatch and quote a flat-rate diagnostic fee.

2

On-site diagnosis

We test ignition, gas pressure, airflow, electrical and controls — and show you exactly what's wrong.

3

Approved repair

Flat-rate written quote. No work until you say yes. We carry common parts on the truck.

4

Verify & warranty

We confirm safe operation, document the fix, and back the repair with a 1-year labor warranty.

Rebates & incentives

Thinking about an upgrade instead?

If repair doesn't make sense, we'll show you rebate-adjusted replacement options. Most projects stack at least two of these.

Heater Repair FAQs

How fast can you repair my heater?
Most same-day calls placed before 11 AM are repaired the same day. We run 24/7 emergency dispatch for no-heat calls — call (818) 697-6699 for current ETA.
My furnace turns on then shuts off quickly — what's wrong?
That's short-cycling. Common causes are a clogged filter, a faulty flame sensor, an overheating limit switch, or a thermostat issue. We diagnose the exact cause rather than swapping parts at random.
Is a heater that won't ignite dangerous?
A furnace that won't ignite usually isn't dangerous, but repeated ignition attempts with a gas valve open can be. If you smell gas, leave and call your utility. For no-ignition with no gas smell, call us and we'll diagnose the igniter, flame sensor, or gas valve.
Should I repair or replace my heater?
If your furnace is 15+ years old and the repair exceeds about 30% of replacement cost, replacement usually wins — especially with heat-pump rebates available. We'll show you both options honestly during the visit.
Do you repair all heater types?
Yes — gas furnaces, electric furnaces, heat pumps, and ductless mini-split heating from all major brands including Ruud, Rheem, Trane, York, American Standard, Day & Night, and Mitsubishi.
