Florence-Graham sits inland in the LA Basin, where summer nights stay hotter than beachside neighborhoods and winter mornings can dip into the low 40s. That temperature swing puts real load on heating systems, especially in the area’s dense stock of 1940s–1960s bungalows that were never built with central air. We’ve spent nearly two decades working on exactly these systems — from gravity furnaces in converted duplexes near Firestone Boulevard to modern high-efficiency units in the blocks around Roosevelt Park.
Why Crestview Heating & Air California Is Florence-Graham’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ customer reviews didn’t come from easy jobs. It came from showing up in Florence-Graham when competitors got stuck at permit counters or turned down work on older systems. Owner Marcus Feldman still serves as Service Manager, which means the person answering your questions about heat exchanger cracks or gas valve failures is the same person accountable for the fix.
That matters in Florence-Graham because this unincorporated LA County community runs on its own building and safety system. Technicians coming from Watts or Huntington Park sometimes misroute permits to City of LA, killing a project timeline. We don’t. We’ve done enough furnace replacements on Compton Avenue, on 77th Street, and in the blocks around Graham Park to know the LA County portal, its fee schedules, and its inspection windows by heart.
Our response time to Florence-Graham is built around that familiarity. We know which streets narrow to single lanes, where parking gets tight near the commercial strips on Florence Avenue, and how to stage a full furnace replacement in a backyard with limited access. That local knowledge translates to faster arrivals and jobs that don’t stretch across multiple days because of logistical surprises.
Our Heating & Furnace Services in Florence-Graham
Furnace Repair
A furnace that won’t ignite, blows cold air, or cycles constantly in a Florence-Graham winter isn’t just uncomfortable — it can be unsafe. We diagnose and repair all major brands, from a 15-year-old Goodman in a bungalow near Nadeau Street to a newer Trane system in a commercial space off Florence Avenue. Most repairs run $150–$700 and finish in a single visit.

Furnace Replacement
This is where Florence-Graham’s housing stock gets interesting. Most of these post-WWII wood-frame bungalows and converted duplexes never had central HVAC installed originally. On a 1950s bungalow on Compton Avenue, we replaced a failing 40-year-old gravity furnace with a new 95% AFUE Carrier gas furnace, running a fresh gas line and ductwork through the tight crawlspace to fit the low ceiling. Full replacement with new ductwork typically falls in the $3,500–$7,500 range, though tight attic spaces and low ceilings can push toward the higher end.

Furnace Tune-Up
Florence-Graham’s basin location means humid air and biological growth that clogs condensate drains faster than drier inland areas. Our tune-ups run $80–$200 and include drain clearing, burner cleaning, and combustion analysis. We recommend annual service before the heating season, especially for older units pulling combustion air from dusty garage spaces.

Heat Exchanger Inspection & Replacement
Coastal salt air accelerates corrosion on uncoated heat exchangers, causing cracks and CO leaks within 10–12 years instead of the 15–20 you’d expect inland. We inspect with cameras and combustion analyzers, and we replace cracked exchangers when repair isn’t safe. Heat exchanger work runs $150–$700. If your carbon monoxide detector has chirped or you’ve noticed headaches when the heat runs, call immediately — this is not a wait-and-see repair.

Gas Valve Repair
Intermittent ignition, weak burner flames, or a furnace that won’t stay lit often trace to a failing gas valve. In Florence-Graham’s older systems, valves corrode from salt air and from years of cycling in dusty environments. Gas valve repair or replacement runs $150–$700, and we always test gas pressure and leak-check every connection before leaving.

Trusted Brands We Service in Florence-Graham
Your system, our specialty. We factory-train on nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so we’re never the company that tells you “we don’t work on that.” For Florence-Graham customers, this means faster repairs because we stock common parts for Trane, Lennox, Goodman, and Rheem systems locally, and we know the quirks of each manufacturer’s ignition sequences and control boards. A 20-year-old Rheem in a Graham Park bungalow gets the same technical attention as a new Lennox in a commercial space off Firestone Boulevard.
Common Heating & Furnace Problems We See in Florence-Graham Homes
- Salt-air corrosion on heat exchangers. The marine layer reaches farther inland than most people realize, and uncoated steel heat exchangers in Florence-Graham develop pinhole leaks and cracks a full third faster than in San Bernardino or Riverside. We catch this with camera inspections during tune-ups.
- Condensate drain clogs from humid basin air. Florence-Graham’s density and pavement coverage amplify humidity, and biological growth in condensate lines triggers safety shutdowns. We clear drains and treat with antimicrobial tablets as standard practice.
- Combustion air contamination in old bungalows. Many 1950s furnaces were installed in closets or garages without dedicated outside air, pulling in dust, auto exhaust, or paint fumes. This fouls burners and flame sensors, causing erratic operation. We assess combustion air sources on every service call.
- Misrouted permits delaying replacements. Contractors unfamiliar with Florence-Graham’s LA County jurisdiction submit to City of LA and wait weeks for rejection. We’ve seen customers stuck without heat for 10+ days because of this single error. We file correctly the first time.

The high end accounts for full replacements in homes with no existing ductwork, tight crawlspaces, and LA County permit requirements. We don’t quote over the phone for replacement work because every bungalow on Compton Avenue or 77th Street presents different access and duct routing challenges. What we do promise: free estimates with upfront pricing once we’ve seen your system, and no work without your written approval.

FAQs — Heating & Furnace in Florence-Graham
Yes, all furnace replacements in Florence-Graham require a permit through LA County Department of Public Works Building and Safety, not the City of LA system used in Watts just blocks away. Misrouting your permit to City of LA is a common, costly mistake that delays projects by weeks. We file correctly through the LA County portal and coordinate inspections so your job stays on track. Call (844) 560-6978 and we’ll walk you through the permit timeline for your specific address.
A burning or exhaust smell usually means a cracked heat exchanger, which can leak carbon monoxide into your home. In Florence-Graham, salt-air corrosion causes this failure 3–5 years earlier than inland areas. Turn off your furnace and call us immediately — this is a safety hazard, not a nuisance. We inspect with combustion analyzers and cameras, and we won’t restart a system with a confirmed crack.
Yes, and we do this regularly in Florence-Graham. Most bungalows here were built without central HVAC, so we design low-profile duct systems or recommend ductless mini-splits for tight attic spaces. On a 1950s bungalow on Compton Avenue, we ran new ductwork through a tight crawlspace to fit the low ceiling. Every home is different, so we start with a free in-person assessment. Call (844) 560-6978 to schedule.
Once yearly, ideally in early fall before heating season. Florence-Graham’s humid basin air and salt particulates accelerate wear on burners, flame sensors, and condensate drains. Our $80–$200 tune-up includes drain clearing, combustion analysis, and salt-corrosion inspection of the heat exchanger. Annual service catches problems before they become mid-winter emergencies.
It could be. A failing gas valve causes weak or intermittent flame, which triggers the high-limit switch and shuts down the burner. But short-cycling also stems from dirty flame sensors, restricted airflow from clogged filters, or oversized equipment. We diagnose the actual cause rather than guessing at parts. Gas valve repair runs $150–$700 if that’s the culprit. Call (844) 560-6978 for a same-day diagnostic — estimates are free.
