We’re Crestview Heating & Air California, and our Heating & Furnace team makes the trip to Los Angeles regularly from our San Jose base. After 19 years in this business, we’ve learned that furnace work here isn’t like furnace work in the suburbs. Los Angeles’s older neighborhoods are packed with pre-war bungalows, Spanish Colonial Revival homes, and low-rise apartments that were built before central forced-air was standard. That means tight access, creative venting, and jobs that start with “can you even fit a furnace in here?” We’ve heard it. We’ve solved it.

Marcus Feldman, our owner, still manages every job as Service Manager. When you call, you’re talking to someone with skin in the game, not a dispatcher reading from a script. We know the alley-loaded buildings in Pico-Union, the narrow crawlspaces under 1920s Craftsman homes in the 90007 ZIP, and the parking headaches on Hoover Street. That local knowledge saves you time and prevents the callbacks that happen when a technician treats your 1938 floor furnace like a standard suburban install.

Why Crestview Heating & Air California Is Los Angeles’s Preferred Heating & Furnace Company

Our reputation in Los Angeles is built on showing up prepared for housing stock that throws curveballs. We’ve got 250+ customer reviews averaging 4.8 stars, and a significant share of those come from Los Angeles homeowners who were tired of being told their system was “too old” or “too weird” to fix. We don’t outsource to anonymous techs. Marcus Feldman oversees every job personally, and that ownership-level accountability means we don’t disappear when a permit issue or HERS verification step gets complicated.

Response time to Los Angeles varies by traffic, but we schedule strategically. We batch South Central and Pico-Union calls on the same days to minimize your wait, and we carry parts for Trane, Lennox, Goodman, and Rheem so we’re not making a second trip because your gas valve wasn’t on the truck. Our customers in Koreatown and Echo Park tell us that’s the difference between a one-day fix and a week of space heaters.

We also understand the local compliance landscape. Every permitted HVAC job in California requires a third-party HERS-certified rater to field-verify duct leakage and refrigerant charge before the permit closes. This isn’t optional, and it doesn’t exist in Arizona or Nevada. We schedule that step for you, explain what the rater is looking for, and make sure your paperwork is clean so you’re not chasing permits for months.

Our Heating & Furnace Services in Los Angeles

Furnace Repair

Furnace repair in Los Angeles often means troubleshooting systems that have been jury-rigged through decades of landlord neglect. We see gas valves seized on 60-year-old wall heaters, rollout switches tripped from inadequate combustion air in closet installs, and thermocoubers failing in floor furnaces that haven’t been serviced since the 1980s. Our diagnostic fee applies toward repair, and we stock common parts for Goodman, Rheem, Lennox, and Trane systems. If you’re in a 1920s bungalow near the 90007 ZIP with a rusted floor furnace, we’ve been there. Salt air accelerates corrosion in coastal-adjacent neighborhoods, and we know what to look for before we quote.

Furnace Replacement

This is our most called-upon service in Los Angeles, and for good reason. Much of the housing stock in the 90001–90010 corridor predates central ductwork entirely. Replacing a furnace here frequently means designing a full forced-air system from scratch, or retrofitting ductless mini-splits as a zoned alternative. We handle the load calculation, the Title 24 compliance paperwork, the permit pull, and the mandatory HERS rater appointment. In a 1938 Spanish Colonial Revival home on Hoover Street in the 90007 ZIP, we found the original floor furnace rusted through and the homeowner relying on space heaters. We designed and installed a complete Carrier gas furnace system with new ductwork stubbed through the attic and crawlspace, then scheduled the required HERS rater to field-verify duct leakage and refrigerant charge before the permit closed. That’s the level of project management you need when your home wasn’t built for this.

Furnace Tune-Up

A furnace tune-up in Los Angeles is preventive maintenance that pays off when Santa Ana winds hit in October and November. Temperatures spike above 95°F with single-digit humidity, and that’s when wall heaters and floor furnaces that haven’t run since February get turned on for the first time. Gas valves stick. Pilot assemblies clog. Heat exchangers crack from thermal shock. Our $95–$235 tune-up includes combustion analysis, gas pressure check, heat exchanger inspection, and safety control testing. For homes in View Park-Windsor Hills and Silver Lake with older systems, we recommend annual service. The urban heat island pushes inland neighborhoods 10–15°F hotter than the Westside on peak summer days, but winter still comes, and a failed furnace in a poorly insulated 1940s apartment is no joke.

Heat Exchanger Repair & Replacement

Cracked heat exchangers are a safety issue we take seriously. In Los Angeles’s older rental stock, we find original equipment pushed well past its design life, with heat exchangers corroded from years of improper venting or condensation drainage. We don’t patch and pray. If the heat exchanger is cracked, we explain your options: replacement part (if available for your model), furnace replacement, or in some cases a ductless retrofit if the existing system is beyond salvage. We use combustion analyzers to verify safe operation before we leave, and we’ll show you the readings.

Ignitor Replacement

Hot surface ignitors fail regularly in Los Angeles’s dry climate, and they’re a common no-heat call in November when systems fire up after months of disuse. We carry ignitors for Lennox, Goodman, Rheem, and Trane systems, and most replacements take under an hour once we’ve diagnosed the failure. If your ignitor is failing repeatedly, we’ll check gas pressure and venting — chronic failures usually point to an underlying problem.

Gas Valve Repair

Gas valve repair is critical work, and we don’t recommend DIY attempts. These valves control fuel flow to your burner, and improper handling creates a genuine hazard. In Los Angeles, we see gas valves seize on wall heaters during Santa Ana wind events when the furnace is finally turned on after a mild fall. We also find improvised venting in tight alley-loaded rentals where the furnace closet is too small for proper combustion air supply. Our gas valve service includes pressure testing, leak detection with electronic sniffers, and verification against manufacturer specs. If the valve is obsolete, we’ll source a compatible replacement or discuss upgrade options.

Trusted Brands We Service in Los Angeles

Your system, our specialty. We maintain factory-trained compatibility across nine major brands, and for Los Angeles customers we stock common parts for Trane, Lennox, Goodman, and Rheem — the four we see most often in this market. That means faster turnaround when your furnace fails on a cold November night and you’re not waiting a week for a gas valve to ship from out of state. We’ve worked on every system type, age, and configuration these brands have produced in the last four decades. From emergency calls to commercial buildouts, if it heats air, we can fix it.

Common Heating & Furnace Problems We See in Los Angeles Homes

• Original cast-iron floor furnaces rust through or crack, especially in older bungalows near the coast where salt air accelerates corrosion. We replace these with modern gas furnaces or ductless systems, but the job always starts with assessing whether your subfloor and framing can support a new unit.
• Gas valves on 60-year-old wall heaters seize up during Santa Ana wind events when the furnace is finally turned on after a mild fall, causing no-heat calls in November. The temperature swings stress components that haven’t moved in months.
• In tight alley-loaded rentals, combustion air supply is often inadequate because the furnace closet is too small and venting was improvised, leading to rollout or carbon monoxide leaks. We measure combustion air requirements against the space available and won’t leave a system running unsafe.
• Thermostats misread in homes with no insulation, which describes much of the 1920s–1950s stock in South Central and Pico-Union. The furnace runs constantly but the house never warms, and homeowners blame the equipment when it’s really the building envelope. We’ll tell you honestly if that’s your situation.
