We’ve been serving West Hills homeowners for nearly two decades, and we know this neighborhood isn’t like the rest of the San Fernando Valley. The same mountain walls that trap summer heat also create sharp winter temperature drops once the sun sets behind the Simi Hills. Your furnace works harder here than in coastal-influenced areas, and the original duct systems in those 1960s–70s ranch homes near Victory Blvd and Fallbrook Ave weren’t designed for that load. That’s why local experience matters. Our Heating & Furnace team doesn’t guess at West Hills conditions, we’ve tracked them across hundreds of service calls.
Why Crestview Heating & Air California Is West Hills’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ reviews reflects real jobs in real homes, including dozens in the West Hills area. Customers here mention the same thing repeatedly: they want someone who understands the split personality of this climate, blistering afternoons, chilly evenings, and how that cycling stresses furnace components.
Marcus Feldman, our owner, still serves as Service Manager. That means when you call Crestview, you’re not getting a dispatcher reading from a script. You’re getting a 19-year HVAC veteran who reviews the job details personally. In West Hills, that ownership-level attention translates to catching things like unbalanced zone dampers in hillside custom homes that a standard technician might miss.
We carry factory-authorized parts for Trane, Lennox, Goodman, and Rheem systems, so West Hills customers aren’t waiting on special orders while their furnace sits cold. Most repairs in the 91307 and 91308 zip codes are completed in a single visit.
Our Heating & Furnace Services in West Hills
Furnace Repair
Furnace repair in West Hills runs $150–$700 depending on the component and accessibility. The most common calls we get from the ranch-style tract homes near Victory Blvd involve short-cycling caused by degraded flex duct in those scorching attics. When supply air leaks into the attic at 25–35%, the furnace can’t maintain pressure, so it kicks on and off repeatedly. We fix the immediate failure, whether that’s a gas valve, ignitor, or blower motor, but we also flag the duct leakage because repairing one without addressing the other just guarantees a callback. Our West Hills customers appreciate that upfront honesty.
Furnace Replacement
A full furnace replacement in West Hills typically costs $3,500–$7,500 including equipment, permits, and labor. Homes in the 91307 flatlands often have straightforward swaps, but the hillside properties off Fallbrook Ave and King George Ave present real challenges. Multi-zone systems, elevation changes of 100–300 feet across a single lot, and custom ductwork from the 1980s–90s build era mean cookie-cutter installs fail here. We size every replacement to actual heat load, not just square footage, and we verify zone balancing before we leave. Marcus personally reviews hillside replacement specs to catch pressure imbalances that standard crews miss.
Furnace Tune-Up
Our furnace tune-up in West Hills costs $80–$200 and includes full combustion analysis, heat exchanger inspection, gas pressure verification, and filter assessment. Given the Santa Ana wind events that channel through the Santa Susana Pass corridor, we pay special attention to filter loading and blower amp draw. A clogged filter in West Hills can overwork a blower motor in weeks, not months. We also inspect attic duct conditions on every tune-up because that 150°F+ cavity degrades seals faster than anywhere else in the LA metro. Annual tune-ups are the minimum here; many of our West Hills customers move to twice-yearly after seeing their first inspection report.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the most serious furnace issue we encounter in West Hills, and it’s more common here than the Valley average. The extreme thermal cycling, hot days, cold nights, forces expansion and contraction that cracks thin-walled exchangers, especially in original 1970s units still running near Victory Blvd. A cracked exchanger can leak carbon monoxide. We test every exchanger with visual inspection and combustion analysis. Replacement runs toward the higher end of our repair range, often $600–$1,200 depending on accessibility, but it’s not optional. If we find a crack, we shut the system down and walk you through replacement options. Safety isn’t negotiable.
Ignitor & Gas Valve Repair
Ignitor replacement and gas valve repair are among our most frequent West Hills calls, especially as original equipment in 1990s hillside homes reaches end of life. A failing ignitor causes intermittent or no heat; a sticking gas valve creates dangerous delayed ignition or rollout. We stock both hot-surface ignitors and universal gas valves for Trane, Lennox, Goodman, and Rheem systems, so most West Hills repairs are same-day. Gas valve work requires careful pressure testing and leak verification, something our owner-managed crews never rush.

Trusted Brands We Service in West Hills
We service nine major HVAC brands, and we maintain active dealer relationships and parts inventory for Trane, Lennox, Goodman, and Rheem. That matters in West Hills because many hillside custom homes run Carrier or Bryant zoned systems from the 1990s build wave, and those proprietary zone boards and damper motors aren’t stocked at every supply house. Our factory-trained technicians carry the diagnostic tools and common failure parts for these systems, which means less downtime for your home. Whether you’ve got a 30-year-old Goodman in a Victory Blvd ranch or a multi-zone Carrier in the 91308 hills, your system is our specialty. We don’t tell West Hills customers to call someone else.
Common Heating & Furnace Problems We See in West Hills Homes
- Attic duct degradation in pre-1985 ranches. The original flex duct in Canoga Park–era homes runs through unshaded attics that hit 150–160°F. Mastic seals cook off, insulation crumbles, and leakage hits 25–35% before most homeowners notice. The furnace short-cycles, runs longer, and dies young.
- Filter clogging during Santa Ana events. The Santa Susana Pass funnels wind-borne particulate directly into West Hills. We’ve seen filters loaded in three weeks that should last three months. The blower motor overamps, heat exchangers run hot, and safety limits trip.
- Zone imbalance in hillside custom homes. Properties on King George Ave and the Fallbrook Ave ridge have elevation drops of 100–300 feet. Original zone dampers were rarely calibrated for this, so upstairs rooms overheat while downstairs stays cold. Equipment swaps without rebalancing make it worse.
- Original furnace end-of-life in 1970s stock. The ranch homes near Victory Blvd and the flat 91307 areas often have 40+ year furnaces. Heat exchangers crack, burners rust, and replacement parts vanish. We give honest repair-versus-replace guidance based on safety, not sales pressure.
Pricing for Heating & Furnace in West Hills, CA

| Furnace Repair | $150 – $700 |
| Furnace Replacement | $3,500 – $7,500 |

What moves you within these ranges? Accessibility matters. A furnace in a tight attic closet off Fallbrook Ave takes longer than a garage-mounted unit near Victory Blvd. Component grade matters too. A standard single-stage gas valve costs less than a modulating valve for a high-efficiency system. And permit requirements through LADBS add cost but protect your home’s value and safety record.

FAQs — Heating & Furnace in West Hills
Short-cycling after a tune-up usually means the root cause wasn’t addressed. In West Hills, the culprit is often duct leakage in that 150°F+ attic, not the furnace itself. A tune-up cleans and adjusts the unit, but if 30% of your heated air is dumping into the attic through cracked flex duct, the system overheats and shuts down on high limit. We inspect attic duct on every call because we’ve learned to fix the whole system, not just the box.
Yes, and it’s a specific problem we see in West Hills hillside properties. The elevation change from your lower floor to upper rooms creates natural pressure differences that standard zone systems don’t self-correct. On a recent job near Fallbrook Ave in the 91308 hillside pocket, we repaired a zoned Carrier gas furnace that was short-cycling because the original 1990s installer never balanced the supply runs across the two-story elevation difference. Our crew recalibrated the dampers and replaced a failing ignitor to restore even heat throughout the home. We bring manometers and flow hoods to verify balance, not guesswork.
Check monthly and replace every 4–6 weeks during active Santa Ana wind periods. The Santa Susana Pass corridor channels intense particulate loads into West Hills that clog standard 1-inch pleated filters in a fraction of their rated life. We’ve pulled filters from hillside homes that were completely loaded in three weeks. If you’re running the system daily, upgrade to a 4-inch media filter cabinet if your duct allows it, the larger surface area extends change intervals and protects your blower motor.
Usually no, and we’ll tell you straight. Original furnaces from the Canoga Park–era builds are now 45–55 years old. Heat exchangers crack, replacement parts are obsolete, and efficiency ratings of 60–70% mean you’re sending 30–40 cents of every gas dollar up the flue. We evaluate each system individually, but when we find rusted burners, degraded flue connectors, or any heat exchanger anomaly, we recommend replacement for safety. Modern 80–96% efficient systems pay back through lower SoCalGas bills, especially in West Hills’s extended heating season.
Yes. Carrier is common in the 1980s–90s custom homes in the 91308 hills, and we maintain factory-trained compatibility across Carrier’s zone control systems, including the older Infinity and Performance series boards. We stock common ignitors, gas valves, and blower modules for these systems, and Marcus reviews any zone-balancing requirements personally. Your Carrier system won’t be a “call someone else” situation with us. Call (844) 560-6978 to schedule service.
