Why Crestview Heating & Air California Is South Whittier’s Preferred Heating & Furnace Company
We’ve spent nearly two decades in HVAC, and that matters in South Whittier. The 250+ customers who left reviews gave us a 4.8-star average, but the number that counts here is the volume: that’s a lot of furnaces, a lot of heat exchangers, a lot of late-night emergency calls in unincorporated LA County.
Owner Marcus Feldman still manages every job as Service Manager. Not from an office. From the field. When you call Crestview, you’re not getting a dispatcher reading from a script. You’re getting Marcus or a technician he’s directly trained, someone who understands that a floor furnace on Painter Avenue fails differently than a central system in Santa Fe Springs.
Our response time to South Whittier is built around knowing the area. We understand the 90605 zip code covers everything from the older tract homes near Washington Boulevard to the modest splits climbing toward the Puente Hills. That geographic familiarity means we arrive with the right parts, the right tools, and the right expectations for what we’ll find in your crawl space or attic.
The county permitting process here catches contractors off guard. It doesn’t catch us. We’ve pulled enough LA County mechanical permits to know the HERS rater requirements, the Title 24 duct-sealing verification, and the inspection timeline. That saves South Whittier homeowners from the nightmare of a half-finished January replacement stalled at the county.
Our Heating & Furnace Services in South Whittier
Furnace Repair
Furnace repair in South Whittier means dealing with systems that have been cooked by Puente Hills heat trapped against the basin floor, then cycled on and off through mild winters that still demand reliable ignition. We see cracked ignitors, failed gas valves, and blower motors straining in attics that hit 140°F in August. A typical repair here runs $150–$700. We stock parts for Trane, Lennox, Goodman, and Rheem to avoid the delay of a second trip.
Furnace Replacement
This is the big one in South Whittier. Most of the housing stock between 1950 and 1970 never had central forced-air. Original floor furnaces and wall heaters dominate blocks near Telegraph Road and Carmenita Road. Replacing them isn’t a swap. It’s a retrofit. We recently retrofitted a full furnace and AC system for a 1958 tract home on Leffingwell Road. The original floor furnace had to go, but the low-pitch attic left barely 18 inches clearance. We custom-routed ductwork and installed a 96% AFUE Carrier gas furnace with a variable-speed blower to handle the tight plenum space. Full replacements with ductwork typically fall between $3,500–$7,500.
Furnace Tune-Up
A furnace tune-up in South Whittier runs $80–$200 and pays for itself fast. These systems work harder than their design intended. The trapped heat and smog from the Puente Hills accelerate wear on electrical components. Dust from the dry, inland climate clogs filters faster than coastal homes. We clean burners, test gas pressure, inspect heat exchangers for cracks, and verify venting. For homes with original floor furnaces, we check combustion safety with extra care. Unpermitted DIY swaps are common here, and we’ve found improper venting that could have killed a family.
Heat Exchanger Inspection & Replacement
In 1950s-70s tract homes, original floor furnaces often develop cracked heat exchangers from decades of thermal cycling, requiring full replacement rather than repair. This is the most dangerous failure we find in South Whittier. A cracked exchanger leaks carbon monoxide into living spaces. We use combustion analyzers and visual borescope inspection. If it’s cracked, we red-tag the unit and discuss replacement options. No patch, no “wait and see.” The liability is too high, and your family’s safety isn’t negotiable.

Trusted Brands We Service in South Whittier
Your system, our specialty. We factory-train on nine major brands, and for South Whittier’s common retrofit scenarios, we lean heavily on Trane, Lennox, and Goodman. Trane’s variable-speed furnaces handle the tight plenum spaces in low-clearance attics. Lennox offers slim-line cabinets that fit where older equipment won’t. Goodman delivers reliable value for homeowners facing the sticker shock of a full-system replacement. We stock local parts for fast turnaround, and we never tell a South Whittier customer, “We don’t work on that.” With 19 years in the field, we’ve seen virtually every configuration these tract homes can throw at us.
Common Heating & Furnace Problems We See in South Whittier Homes
- Cracked heat exchangers in original floor furnaces. Decades of thermal cycling in 1950s–60s units fatigue the metal. We find this most often in homes near Washington Boulevard and the older sections of 90605. The repair isn’t a repair. It’s a full replacement, and we test for CO leakage before we leave.
- Failed ignitors and gas valves in wall furnaces. These components sit in tight enclosures with poor ventilation, cooked by the inland heat that pools against the Puente Hills. Replacement is straightforward if we catch it before the homeowner tries a DIY fix and strips the gas connection.
- Undersized electrical panels blocking furnace upgrades. Modern 96% AFUE furnaces and variable-speed blowers draw more power than 1960s wiring allows. We see this constantly in South Whittier retrofits. The furnace replacement becomes a panel upgrade, and that requires LA County electrical permits on top of the mechanical permit.
- Improper venting from unpermitted DIY swaps. Unpermitted DIY furnace swaps are common here, leading to safety hazards like improper venting or undersized electrical panels that fail inspection during a county-mandated retrofit. We find Category I furnaces vented into old masonry chimneys without liners, or power-vented units with PVC run through walls that don’t meet clearance. We fix it to code, or we don’t do it.

Second, retrofitting ductwork into homes that never had it requires custom fabrication, not off-the-shelf parts. Third, electrical panel upgrades are common. We quote upfront, itemize everything, and estimates are free. Call (844) 560-6978.
We Also Serve Cities Near South Whittier
Our service radius extends naturally from South Whittier into Whittier proper, East La Mirada, La Mirada, and Santa Fe Springs. Each city has its own inspection regime, its own housing stock, its own failure patterns. Whittier’s incorporated status means city permits, not county. Santa Fe Springs mixes industrial and residential in ways that change the HVAC load calculation. We know the difference because we’ve worked in all of them. If you’re on the border and unsure who covers you, call us. We’ll tell you straight.

FAQs — Heating & Furnace in South Whittier
Yes. Because South Whittier is unincorporated LA County, all HVAC permits are pulled through LA County Building & Safety, not a city department. This means your replacement requires a county mechanical permit, and if you’re changing the equipment type or adding ductwork, you’ll likely need HERS rater verification of duct sealing under Title 24. We handle the entire permitting process as part of our replacement service. Call (844) 560-6978 to discuss your project.
You’re not imagining it. South Whittier’s unincorporated status means LA County permit fees and inspection requirements that incorporated Whittier doesn’t impose. Additionally, the 1950s–70s tract homes here often require more extensive electrical or duct modifications to accommodate modern equipment. The base repair rates are comparable, but the total project cost frequently runs higher due to these structural factors. We itemize every charge so you see exactly where the money goes.
Yes, and it’s one of our most common requests in South Whittier. The process involves removing the floor furnace, designing a duct distribution system for your home’s layout, and installing a modern gas furnace with appropriate venting. Low attic clearances are the main challenge. We custom-fabricate ductwork and select compact equipment. The project typically requires LA County permits and may trigger a HERS rater inspection. Call for a free in-home assessment.
Once yearly, ideally in early fall before the heating season begins. The Puente Hills climate puts extra runtime stress on components, and the dry, dusty inland air clogs filters faster than coastal areas. Annual tune-ups catch cracked heat exchangers, failing ignitors, and gas pressure issues before they become safety hazards or mid-winter emergencies. Our tune-up is $80–$200. Schedule yours at (844) 560-6978.
Yes. LA County requires mechanical inspection for all furnace replacements, and if ductwork is modified or added, a HERS rater must verify duct sealing compliance with Title 24. This county-enforced step catches contractors and homeowners off guard, especially those who recently had work done across the street in the City of Whittier under a different inspection regime. We coordinate all inspections and ensure your system passes before we consider the job complete.
