How do I know if my furnace needs repair or replacement?

Signs your furnace needs repair: won't ignite, blowing cold air, strange noises, frequent cycling, yellow pilot light. Signs it may need replacement: over 15–20 years old, repair costs exceed $600, energy bills rising significantly. ECO gives you an honest assessment — we won't push replacement if repair is the right call.

Is it safe to run my furnace with a cracked heat exchanger?

No — a cracked heat exchanger can allow carbon monoxide to enter your living space, which is a serious safety hazard. If your CO detector goes off or you suspect a heat exchanger issue, shut off the system and call ECO immediately at (818) 294-7515.

Does ECO service gas furnaces and heat pumps?

Yes. ECO Heating & Cooling services all types of heating systems including gas furnaces, heat pumps, dual-fuel systems, electric furnaces, and wall heaters. We service all major brands.

Expert Heating Repair

Valley Winters Get Cold. Your Heating System Needs to Work.

While San Fernando Valley winters are milder than most of the country, temperatures do drop — and a failing furnace on a cold January night is a serious problem. ECO Heating & Cooling has repaired every type of gas furnace and heating system in West Hills, Northridge, Encino, and across the Valley for over 40 years.

Heating Problems We Diagnose & Repair

Furnace won't turn on — ignition failure, gas valve problem, thermostat issues
Furnace starts but won't stay on — flame sensor failure, heat exchanger issues
Heating unevenly throughout the home — duct problems, blower motor failure
Furnace making strange noises — bang on startup, squealing, rumbling
Short cycling — furnace turns on and off rapidly without reaching set temperature
Yellow pilot light (should be blue) — combustion problem, potential CO risk
High gas bills with less heat — efficiency degradation, heat exchanger crack
Thermostat issues — not communicating with furnace, incorrect calibration
Heat pump not heating — reversing valve failure, refrigerant issues in heating mode

⚠️

Safety note: A yellow or orange pilot flame, rotten egg smell, or carbon monoxide alarm indicate a potential gas or combustion safety issue. Call us immediately and leave the home if you suspect a gas leak.
