A broken furnace in Los Angeles might not mean subzero temperatures, but temperatures drop into the 40s in Hollywood winters and the 30s in the San Fernando Valley. LC Heating & Air repairs all types of furnaces — gas, electric, heat pump, and dual-fuel — throughout Greater Los Angeles. We prioritize furnace calls because a failed heat exchanger or gas leak can be dangerous. We respond quickly and diagnose safely.
Los Angeles is one of the most diverse HVAC markets in the country. From Mid-City bungalows and Koreatown apartments to Westside estates and South LA single-family homes, every property type presents different comfort challenges, equipment ages, and access constraints.

Local HVAC Challenges
Los Angeles homeowners face a combination of aging infrastructure and accelerating climate stress. Many central LA homes were built before air conditioning was standard, meaning retrofitted ductwork is often undersized, leaky, or poorly routed through tight attic spaces. Inland neighborhoods and properties east of the 405 experience significantly higher summer design temperatures than the coast — equipment sized for mild coastal conditions will struggle on 100-degree days.
Furnace failures in Los Angeles are more common than most homeowners expect. Many LA homes have furnaces that are 20 or even 30 years old — they run infrequently enough that homeowners do not notice gradual decline until the system fails completely during the first cold snap of the season. The most common failures we see in older LA furnaces: igniter failure, cracked heat exchangers, failed blower motors, dirty flame sensors that cause nuisance shutdowns, and degraded draft inducer motors.
Neighborhood Context
LA's housing stock spans Craftsman bungalows, Spanish Revival duplexes, mid-century ranch homes, and newer infill construction — often on the same block. This diversity means cookie-cutter HVAC recommendations fail. We perform site-specific load calculations, assess duct condition on every installation, and recommend mini splits where central ductwork would be too invasive or inefficient.
Utility programs vary by service territory — LADWP for most of the city, with different rebate structures than SoCalGas — and we help homeowners identify applicable incentives during estimate appointments.
Carbon Monoxide Safety and Furnace Repair
Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete combustion in gas furnaces. A properly functioning furnace contains all combustion gases within the heat exchanger and vents them safely outside through the flue. When a heat exchanger develops cracks — which happens over time due to the repeated heating and cooling cycles that cause metal fatigue — combustion gases can leak into the conditioned airstream.
LC Heating & Air performs a carbon monoxide safety check on every furnace repair call. We measure CO levels at the furnace plenum, the supply registers, and in the ambient room air. If we detect elevated CO levels or a confirmed heat exchanger crack, we will shut off the furnace immediately and advise against operating it until the issue is resolved.
Our Diagnostic Process
We start with safety first: checking for gas leaks and CO levels before diagnosing. If there's a safety issue, we address it first. Our technicians then perform a full system diagnosis, checking the heat exchanger, ignitor, gas valve, limit switch, control board, blower motor, and flue venting.
After the inspection, we provide a written price estimate. We explain the issue and give you a flat price. If repair doesn't make sense, we'll tell you. Once approved, we repair the issue, verify combustion, test CO levels, and confirm all safety limits are operating correctly.
Repair vs. Replace
We utilize the '5,000 Rule': multiply the age of your equipment by the estimated cost of the repair. If the total exceeds $5,000, replacement is mathematically the smarter investment. At 15 years old, most systems use obsolete R-22 refrigerant and operate at very low efficiency.
We tell you exactly what's wrong and what it will cost. We'll tell you if repair doesn't make financial sense. We don't push for replacement unless the repair is a bad investment for you.
Cost and Rebate Factors
The cost for a new AC or furnace installation in Los Angeles depends heavily on ton size, efficiency ratings, and whether your existing ductwork requires modification. We provide free, upfront written estimates before any work begins.
Through the TECH Clean California program and the federal Inflation Reduction Act (IRA), homeowners can access thousands of dollars in rebates and tax credits when upgrading to qualifying high-efficiency heat pumps. We help you navigate these incentives.
Access and Scheduling
We check access, electrical, duct condition, airflow, and equipment placement before recommending a repair or replacement. Our team is experienced with the tight access points common in older LA homes and the specific requirements of gated properties.
Emergency calls are answered within 30 minutes (phone response). We stock ignitors, limit switches, control boards, and gas valves for the most common furnace brands on our trucks to facilitate same-day repairs whenever possible.
Common Furnace Mistakes
One of the biggest mistakes we see is neglecting annual maintenance. A dirty flame sensor or a failing draft inducer motor often gives warning signs weeks before a total breakdown. Annual maintenance catches these issues early.
Another mistake is ignoring the 'burning smell' at the start of the season. While often just dust burning off, it can sometimes indicate electrical issues. If the smell persists or smells like burning plastic, shut the system down and call us.
Making the Right Choice for Your Home
When your furnace stops working, the decision to repair or replace should be based on the facts of your specific system. We look at the age, the cost of the repair, and the overall condition of your ductwork and safety components.
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. We provide the information you need to make a decision that fits your budget and your home's long-term comfort needs.

What Los Angeles customers say about furnace repair
Verified reviews from homeowners in Los Angeles and nearby neighborhoods who used our furnace repair service.
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
