Sherman Oaks sits on the hot side of the Santa Monica Mountains, and that geography shapes everything about how we work here. The 91403, 91413, 91423, and 91495 zip codes cover a stretch of post-WWII ranch homes whose furnaces and ductwork have been baking in attics that hit 150°F+ every summer since the Truman administration. Owner Marcus Feldman still runs service calls personally, and he’s seen enough cracked heat exchangers and earthquake-displaced duct boots in Sherman Oaks attics to know this market isn’t like Santa Monica or Culver City. The marine layer never makes it over the hills here. Your equipment works harder, ages faster, and fails in ways that coastal HVAC techs rarely encounter.
Why Crestview Heating & Air California Is Sherman Oaks’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ reviews didn’t come from easy jobs. It came from showing up in Sherman Oaks when the overnight low dropped to 38°F and a family’s furnace was blowing cold air. Marcus Feldman answers his own phone more often than not, and he still carries the title of Service Manager, which means ownership-level accountability isn’t a marketing line, it’s how we schedule every dispatch.
We know the local streets, from Ventura Boulevard’s commercial corridor up to the hillside homes above Mulholland. That familiarity matters when you’re trying to describe which side of the house your furnace sits on, or whether your attic access is through a closet or the garage. We’re not guessing based on a satellite photo.
Our customers in Sherman Oaks mention the same thing in reviews: we fix it in one trip. That’s not luck. After nearly two decades of HVAC work, we’ve stocked our trucks with parts for Trane, Lennox, Goodman, and Rheem systems, plus the universal components that keep 1960s and 1970s furnaces limping along. We don’t waste your Saturday waiting on a parts run to Van Nuys.
Our Heating & Furnace Services in Sherman Oaks
Furnace Repair
Furnace repair in Sherman Oaks runs $150–$700 depending on what’s failed. The most common calls we get here aren’t the simple ignitor swaps you’d see in newer construction. They’re gas valves that failed after voltage surges during August heat waves, when AC compressors draw peak current and the electrical grid in the Valley strains under demand. We also see cracked heat exchangers in original equipment that’s been thermally cycled through thousands of 150°F attic summers. Our truck carries replacement gas valves, ignitors, blower motors, and heat exchanger inspection cameras so we can diagnose and repair without a return visit.
Furnace Replacement
A full furnace replacement in Sherman Oaks typically costs $3,500–$7,500, including equipment, labor, and any duct modifications your specific home needs. This is where our local knowledge pays off most. On a ranch home near the intersection of Hazeltine and Burbank, our crew found a 1970s Lennox furnace with a cracked heat exchanger worsened by years of attic heat cycling. We replaced it with a high-efficiency Carrier model, rerouting supply ducts that had been knocked loose in 1994 and never resealed, all in one trip to save this self-reliant homeowner another service call. Sherman Oaks replacement jobs often take longer than coastal equivalents because we find earthquake damage that wasn’t part of the original scope. We quote accordingly.
Furnace Tune-Up
Our furnace tune-up in Sherman Oaks runs $80–$200 and includes combustion analysis, heat exchanger inspection, gas pressure verification, and duct leakage assessment. Given the local conditions, we pay special attention to dust accumulation and corrosion on ignitors and flame sensors. The Santa Monica Mountains block the marine layer that naturally flushes salt and moisture from coastal attics. Sherman Oaks attics stay dry and dusty year-round, and that dust cakes onto furnace components in ways that reduce efficiency and create ignition failures. A fall tune-up before the heating season starts catches these issues before you’re waking up to a 52°F house.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the most serious safety issue we encounter in Sherman Oaks’s older ranch homes. A cracked heat exchanger can leak carbon monoxide into your living space, and the thermal stress of cooling from 150°F attic temperatures to heating cycle operation accelerates metal fatigue in ways that don’t happen in milder climates. We inspect with visual borescopes and combustion analyzers. If replacement is needed, we handle the full job, including permit coordination if required. Never operate a furnace with a suspected heat exchanger crack. Call (844) 560-6978 immediately.

Trusted Brands We Service in Sherman Oaks
Your system, our specialty. We maintain factory-trained compatibility across nine major brands, and for Sherman Oaks customers, we stock the parts that fail most often in this climate. Trane and Lennox systems are common in the 1970s hillside builds, while Goodman and Rheem units show up frequently in the flatlands south of Ventura where more homeowners have done mid-life replacements. We don’t tell you “we don’t work on that.” If it’s heating your Sherman Oaks home, we’ve seen it, diagnosed it, and probably have the part on the truck.
Common Heating & Furnace Problems We See in Sherman Oaks Homes
- Cracked heat exchangers from thermal stress. Attics in Sherman Oaks reach 150°F+ in summer, then drop to overnight lows in the 40s. That temperature swing fatigues heat exchanger metal far faster than in coastal zones where attics stay moderated by marine air. We find cracks in 15- to 20-year-old systems that would have lasted 25+ elsewhere.
- Gas valve failures after summer voltage surges. Valley heat waves strain the electrical grid. When your AC compressor kicks on during peak demand, voltage drops and spikes can damage the sensitive electronics in modern furnace gas valves. We replace with valves rated for wider voltage tolerance.
- Ignitor burnout from dust and corrosion. Without marine layer moisture to settle dust, Sherman Oaks attics accumulate fine particulate that insulates ignitors and causes hot spots. The dry conditions also promote corrosion on flame sensor rods. Both issues show up as intermittent ignition failures that get worse over time.
- Hidden duct damage from the 1994 Northridge earthquake. This is the Sherman Oaks specialty. The epicenter sat roughly 4 miles northwest in Reseda, and the shaking displaced flex-duct connections and cracked rigid duct joints throughout the area. Structural contractors patched drywall. HVAC permits weren’t pulled. Twenty-five to thirty-five percent of your heated air has been leaking into the attic ever since, and your furnace has been working overtime to compensate.

FAQs — Heating & Furnace in Sherman Oaks
The 1994 Northridge earthquake shook the Valley hard enough to displace flex-duct boots and crack rigid duct joints in thousands of homes. Structural repairs focused on visible damage, drywall, and foundations. HVAC ductwork, hidden in attics, was rarely inspected unless a homeowner specifically hired an HVAC contractor with a permit. We’ve opened attics in Sherman Oaks and found supply ducts completely detached from boots, with homeowners losing 25–35% of their heated air for thirty years. If your heating bills seem high or rooms heat unevenly, this is the first thing we check. Call (844) 560-6978 for a duct assessment, estimates are free.
Probably, if it’s past 20 years and you’re facing any repair over $400. Original furnaces in Sherman Oaks ranch homes have endured extreme thermal cycling from 150°F+ attic summers, and heat exchanger cracks become a real safety risk at this age. We inspect with combustion analyzers and borescopes to give you a straight answer. If the heat exchanger is sound and efficiency is acceptable, we’ll tell you to run it another season. If we find cracks or corrosion, replacement is the only safe option. The $3,500–$7,500 replacement cost typically pays back in 4–7 years through efficiency gains and eliminated repair bills. Call for an honest assessment.
Yes, significantly. The mountains block marine layer moisture and cooling, so Sherman Oaks attics stay hot and dry year-round. That dryness causes dust accumulation on furnace components, and the extreme summer temperatures thermally stress heat exchangers and venting materials. Your furnace works harder and fails faster than equivalent equipment in Brentwood or Culver City. We account for this in our maintenance recommendations, scheduling more frequent filter changes and earlier ignitor replacement than coastal HVAC contractors might suggest.
Most ranch home furnace replacements in Sherman Oaks fall between $3,500 and $7,500, with the higher end reflecting earthquake-damaged duct remediation, high-efficiency equipment upgrades, or difficult attic access in hillside neighborhoods above Mulholland. The flatlands south of Ventura Boulevard typically see mid-range pricing unless we discover 1994 earthquake damage that wasn’t previously addressed. We quote exact numbers after inspection, never ballpark figures that change mid-job. Call (844) 560-6978 for your free estimate.
We install and service all major brands, but for Sherman Oaks’s thermal stress conditions, we lean toward equipment with robust heat exchanger warranties and proven performance in high-temperature attic installations. Carrier and Trane both offer heat exchanger warranties that match the extended runtime demands of Valley installations. Goodman provides strong value for budget-conscious replacements. The “best” brand depends on your home’s duct configuration, your efficiency goals, and whether we’re remediating earthquake damage as part of the job. We’ll recommend specifically for your situation after inspection, not push whatever’s on promotion.
