Furnace & Heating Repair
When the Cold Hits
Southern California winters are mild — right up until a cold snap drops valley and hillside homes into the 40s overnight and your furnace picks that moment to quit. Energy Control HVAC repairs gas furnaces, heat pumps, and every heating system fast, with a safety-first approach that never cuts corners on gas or carbon-monoxide checks.
Whether it's a failed igniter or flame sensor, a cracked heat exchanger, or a heat pump that won't switch to heating mode, our EPA-certified technicians diagnose the real cause, quote it in writing, and restore safe, even warmth — usually the same day. Every repair is backed by our workmanship guarantee.
Heating repair in Southern California ranges from the mild-winter basin, where a furnace might run a few weeks a year, to the high desert, where Lancaster and Palmdale homes heat hard through freezing nights. We service every type across that range — and never hand back a gas system without confirming it's burning safely.
Signs Your Furnace Needs Repair
Heating problems are worth catching early — partly for comfort, but mostly for safety. Call if you notice:
- No heat or weak heat — often a failed igniter, flame sensor, or a thermostat fault.
- Short cycling — the furnace turns on and off rapidly, usually from overheating or a dirty flame sensor.
- Yellow or flickering burner flame — a healthy gas flame is crisp and blue; yellow can indicate incomplete combustion.
- A burning or acrid smell that doesn't fade — beyond the first startup of the season, this warrants a shut-off and a call.
- Banging, booming, or rumbling on ignition — delayed ignition or a dirty burner, both worth prompt attention.
- The CO detector sounds — leave the house and call the gas company's emergency line first, then us.
Safety Comes First on Every Heating Call
A furnace burns gas and vents combustion byproducts, so heating repair is never just about comfort. On every call we inspect the heat exchanger for cracks, verify safe combustion, and check for carbon-monoxide risk — the CDC reports hundreds of preventable CO deaths in the U.S. each year, and a cracked heat exchanger is a classic cause. If we ever find an unsafe condition, we'll tell you plainly and never return a hazardous system to service. Find local heating repair in Los Angeles, Glendale, Lancaster, and Santa Clarita — where cold desert and valley nights make heating a real need.

Heat pumps and dual-fuel systems
More Southern California homes heat with heat pumps every year, and they fail differently than gas furnaces — a stuck reversing valve, a defrost-control fault, or a refrigerant issue can leave them blowing cool air in heat mode. Our technicians are equally at home on heat pumps, dual-fuel systems, and traditional furnaces, which matters in the high desert where Palmdale and Lancaster homes lean on real heating capacity all winter.
Repair or replace your furnace?
A cracked heat exchanger, a furnace over 15–20 years old, or a repair topping a third of a new system's cost all tip the math toward replacement — especially since a modern heat pump can heat and cool efficiently from one system. We show you both numbers with rebates applied. See HVAC installation for replacement options, and maintenance plans to keep whatever you have running safely.
Types of heating systems we repair
We repair every heating setup common in Southern California homes and light commercial buildings:
- Gas furnaces — by far the most common; we service ignition, gas, airflow, and heat-exchanger issues.
- Heat pumps — increasingly popular; we handle reversing valves, defrost controls, and refrigerant faults.
- Dual-fuel systems — a heat pump paired with a gas furnace for efficiency; we tune the changeover logic.
- Electric & wall heaters — element, sequencer, and control repairs for older or supplemental heat.
How to prevent furnace problems
Most no-heat nights are avoidable. Replace your filter regularly (a clogged filter overheats the furnace and trips its safety limit), keep the area around the furnace clear, and book an annual heating tune-up before winter so a weak igniter or dirty flame sensor is caught in advance. A tune-up also includes the combustion and heat-exchanger safety checks that keep your family safe from carbon monoxide.
Commercial heating repair
Offices, restaurants, and retail spaces rely on rooftop and split-system heat too, and we keep them running with priority response, documented service, and the same safety-first combustion checks we perform on every residential furnace.
Signs your heat pump needs repair
Heat pumps hide their problems well. Watch for a system that runs constantly but never warms the house, ice that stays on the outdoor coil, a unit stuck blowing cool air when you've called for heat, or auxiliary "emergency heat" running far more than it should. Each points to a reversing-valve, defrost-control, or refrigerant issue — all things our technicians can pinpoint and repair before your electric bill balloons.

Licensed, Insured & Certified
Every technician on your job holds EPA Section 608 certification for refrigerant handling and works under our California C-20 HVAC contractor license. That's not a marketing badge — it's federal and state law for this work, and it's your protection against the unlicensed operators who cut corners on refrigerant, permits, and safety. We carry full liability insurance, pull permits where required, and back every job with a written workmanship guarantee. Ask any contractor to prove those three things before you hire them — we volunteer ours.
Free Estimates, Upfront Pricing & Financing
Estimates for heating & furnace repair projects are free, and you approve an itemized written price before any work begins — no verbal numbers that grow on the invoice. For larger jobs we offer financing that turns a big one-time cost into predictable monthly payments, and on qualifying work we apply every utility rebate and federal tax credit you're eligible for, shown right on your quote. Because Southern California cooling season runs long and hot inland, timing matters. Booking non-emergency work in spring or fall means shorter waits and no scrambling during a heat wave — but when something fails at the worst moment, our 24/7 line is answered around the clock.
What to Expect From Your Heating & Furnace Repair Appointment
We try to make hiring us the easy part of your day. When you call, a real person helps you describe the problem and books a window that fits your schedule — with a courtesy heads-up before we arrive. Our technicians show up in uniform, protect your floors, explain what they find in plain language, and hand you an itemized written price to approve before any heating & furnace repair work starts. When the job is done we clean up, walk you through what we did, and make sure the system is performing the way it should before we leave.

Heating Repair Questions
Yes. Our 24/7 line is answered around the clock, and a no-heat night with children, seniors, or medical needs at home gets priority. Call (323) 799-0911 any time and we'll dispatch an on-call technician.
It depends on the fault. Igniters and flame sensors are quick same-day fixes; a cracked heat exchanger is a major repair we weigh against replacement. Either way, we diagnose the cause and give you an exact written price before any work begins.
It can be — a cracked heat exchanger can leak carbon monoxide into your home's air. We inspect it on every heating call, and if we find a crack we'll never return the system to service unsafely. Replacement of the exchanger or furnace is usually the right call.
Common causes include a failed igniter or flame sensor, a thermostat set to 'on' instead of 'auto', a gas-supply issue, or on a heat pump, a stuck reversing valve. We diagnose the exact cause and quote the fix before starting.
Yes. We repair heat pumps, dual-fuel systems, gas furnaces, and electric heat across all major brands — which matters most in high-desert cities like Palmdale and Lancaster where heating runs hard all winter.
Once a year, ideally in fall before you rely on it. An annual heating tune-up cleans the burner and flame sensor, verifies safe combustion, checks the heat exchanger for cracks, and catches the small failures that otherwise become no-heat nights — plus it keeps your manufacturer warranty valid.
Yes. Every heating repair is backed by our written workmanship guarantee, and replacement parts carry their manufacturer warranty. Safety-critical repairs are double-checked before we consider the job complete.
Absolutely. We service every furnace and heat pump regardless of who installed it. Our technicians assess its true condition and safety, then give you honest repair-or-replace options with no pressure.
