Why Crestview Heating & Air California Is Canoga Park’s Preferred Heating & Furnace Company
We’ve built our reputation in Canoga Park one service call at a time. Our 4.8-star average across 250+ customer reviews reflects real outcomes on real jobs, not curated testimonials. When a furnace goes out on a January night near Sherman Way or along Topanga Canyon Blvd, Canoga Park homeowners aren’t calling a distant dispatch center. They’re reaching Marcus Feldman, our Owner and Service Manager, who still manages jobs in the field with nearly two decades of hands-on HVAC experience.
That direct ownership involvement matters in Canoga Park because the heating problems here aren’t generic. The 1950s–70s tract homes that define this neighborhood carry legacy systems with failure modes you simply don’t see in newer developments. A technician who only knows modern equipment will miss the signs of a cracked cast-iron heat exchanger or diagnose a duct-collapse issue as a furnace problem. Our 19 years in the industry means we’ve worked on virtually every system type, age, and brand a Canoga Park customer could own.
We also understand the geography. Canoga Park sits landlocked between the Santa Susana Mountains and the Simi Hills, a heat trap that swings 15–20°F above coastal LA in summer and experiences sharp Santa Ana wind spikes in fall and winter. That thermal stress cycle, year after year, is hard on equipment. It’s hard on ductwork. And it’s why local knowledge beats a generic service script every time.
Our Heating & Furnace Services in Canoga Park
Furnace Repair in Canoga Park
Most furnace repairs in Canoga Park fall between $150–$700, depending on the part and accessibility. We commonly see ignitor failures, blower motor issues, and limit switch trips in the older systems still running in ranch homes near Owensmouth Ave and Victory Blvd. Because we service nine major brands, we don’t tell Canoga Park homeowners “we don’t work on that.” Your system, our specialty.
Furnace Replacement in Canoga Park
Full furnace replacement in Canoga Park typically runs $3,500–$7,500, including equipment, labor, and basic duct connections. This is where our local expertise pays off most directly. Many Canoga Park homes still run original or single-replacement furnaces from the 1960s and 1970s. We recently serviced a 1965 Rheem furnace in a ranch home near Topanga Canyon Blvd where the heat exchanger had developed a hairline crack, leaking CO into the living space. The homeowner chose a full furnace replacement with a high-efficiency Carrier unit rather than patching the 50-year-old system. In cases like this, replacement isn’t just the safer choice. It’s often the more economical one when you factor in energy savings and the rising cost of obsolete parts.
Furnace Tune-Up in Canoga Park
A professional furnace tune-up in Canoga Park costs $80–$200 and should happen annually, ideally before the first Santa Ana wind event of fall. Our tune-ups include combustion analysis, heat exchanger inspection, gas pressure verification, and duct-static pressure readings. In Canoga Park’s 150°F attics, we pay special attention to flex duct condition. Collapsed or separated ductwork is the hidden driver behind most “my furnace runs but the house never gets warm” complaints we hear near De Soto Ave.
Heat Exchanger Inspection & Replacement in Canoga Park
This is the critical one for Canoga Park’s older housing stock. The neighborhood’s 1950s–70s ranch homes often still run on original gravity or early forced-air furnaces with cast-iron heat exchangers that crack from decades of thermal stress, a failure mode virtually unseen in newer developments. A cracked heat exchanger can leak carbon monoxide into living spaces. It’s not repairable. When we find a crack, we red-tag the unit and discuss replacement options immediately. The cost to replace a heat exchanger alone, when parts are even available, often approaches half the cost of a new furnace. For most Canoga Park homeowners with systems over 20 years old, we recommend full replacement.
Gas Valve Repair in Canoga Park
Gas valve failures on vintage furnaces present a specific challenge in Canoga Park. Replacement parts for 1960s and 1970s valves are increasingly unavailable from local suppliers. When we can source a compatible valve, repair typically falls in the lower end of our $150–$700 repair range. When we can’t, we present replacement options honestly. Owner-managed, not outsourced means you get a straight answer, not a runaround while someone checks with a warehouse three counties away.

Whether you have a 30-year-old Lennox in a ranch off Vanowen St or a newer Goodman system in a Warner Center condo, we carry the components to get you running without a multi-day parts chase. From emergency calls to commercial buildouts, our technical range matches Canoga Park’s unusually wide split between aging residential retrofit work and commercial rooftop-unit service.
Common Heating & Furnace Problems We See in Canoga Park Homes
- Cracked cast-iron heat exchangers in original 1960s furnaces. The thermal cycling between Canoga Park’s cool winter nights and Santa Ana-driven dry heat spikes fatigues cast iron over decades. We find this most often in unmodified ranch homes between Sherman Way and Roscoe Blvd, where the original furnace has never been replaced.
- Flex duct collapse in 150°F attics, blocking airflow and causing furnace short-cycling. In the older ranch homes clustered around Topanga Canyon Blvd, technicians routinely find original flex duct that has partially collapsed or separated at joints inside attics exceeding 150°F. A combination that can slash measured system efficiency by 30–40% and goes undiagnosed for years because the equipment itself tests fine on the ground.
- Failed gas valves on vintage furnaces where replacement parts are no longer stocked by local suppliers. Canoga Park’s inventory of 1960s and 1970s gas valves has dwindled. When we encounter a failed valve on a system that’s already outlived its design life, we discuss whether a new valve hunt makes sense or if that money is better applied to a modern, efficient replacement.
- Furnace short-cycling due to restricted return air from aging duct design. Original Canoga Park tract homes were built with minimal return-air pathways. Add decades of duct degradation, and the furnace overheats and shuts down prematurely. The fix isn’t always the furnace. Sometimes it’s the duct system that needs attention.

FAQs — Heating & Furnace in Canoga Park
The combination of decades of thermal cycling and Canoga Park’s specific cast-iron construction is the culprit. Coastal LA’s more moderate temperature swings produce less thermal stress on metal, and newer developments rarely use cast-iron heat exchangers at all. In Canoga Park’s 1950s–70s ranch homes, original furnaces have endured 50+ years of expansion and contraction. The Santa Ana wind events add sharp dry-heat spikes that accelerate fatigue. If your Canoga Park home has never had a furnace replacement, we recommend annual heat exchanger inspection. Call (844) 560-6978 to schedule.
For a 1965 furnace, replacement is usually the smarter investment. Gas valves for systems that old are often obsolete, and even when we can source one, the repair cost plus the remaining system’s inefficiency and safety exposure rarely pencils out favorably. A new high-efficiency furnace will cut your gas bills significantly, especially during Canoga Park’s cold snaps when the old system would run continuously. We offer free replacement estimates. Call (844) 560-6978 and we’ll walk through the numbers for your specific setup.
The warning signs are uneven heating between rooms, a furnace that runs constantly without reaching thermostat setpoint, and unexpectedly high gas bills despite normal equipment operation. In Canoga Park’s 150°F attics, original flex duct stapled through unconditioned spaces degrades faster than homeowners realize. We measure static pressure and perform visual attic inspections during tune-ups to catch this. If you’re experiencing these symptoms in a ranch home near Topanga Canyon Blvd or De Soto Ave, the ductwork is a prime suspect. Call (844) 560-6978 for diagnosis.
Yes, because efficiency gains apply to every heating hour, not just extreme cold. Canoga Park may not see Midwestern winters, but when Santa Ana winds drop temperatures into the 30s, a 95% AFUE furnace uses substantially less gas than an 80% unit or a vintage 60% system. The payback accelerates if you’re replacing a cracked heat exchanger on an obsolete unit anyway. We size equipment specifically for Canoga Park’s heat-trap climate, not a generic Los Angeles average. Request a free estimate at (844) 560-6978.
Direct wind damage to the furnace itself is rare, but Santa Ana conditions create secondary problems. Extreme dry heat spikes stress heat-pump reversing valves if you have a dual-fuel system, and the high winds drive dust and debris into outdoor components. More critically for Canoga Park homeowners, the sharp temperature drops that follow Santa Ana events force heating systems to cycle rapidly from idle to full output. That thermal shock is hardest on aged cast-iron heat exchangers. We inspect for this specific stress pattern during fall tune-ups. Schedule yours at (844) 560-6978.
