Why Crestview Heating & Air California Is Los Gatos’s Preferred Heating & Furnace Company
We’ve built our reputation in Los Gatos one service call at a time. Our 4.8-star average across 250+ customer reviews includes plenty of Los Gatos homeowners who found us after frustrating experiences with valley-floor techs who didn’t understand mountain propane systems or coastal corrosion patterns.
Owner Marcus Feldman still serves as Service Manager, which means the person answering your questions about that strange furnace noise is the same person who’ll show up with the right parts. Not a dispatcher. Not a franchise script. Marcus has 19 years in the field, and he’s personally handled furnace repairs from the 95030 downtown core to the 95033 ridgeline.
Our location in San Jose puts us on Highway 85 and 17 within 20 minutes of most Los Gatos addresses. We’ve timed it. That matters when your furnace quits on a January night and the temperature’s dropping toward freezing in the Aldercroft Heights area.
We also understand something most competitors don’t: Los Gatos straddles two genuinely different climate zones. The valley floor at ~400 feet and the Santa Cruz Mountains above 1,500 feet require different equipment knowledge, different fuel types, and different safety protocols. A technician who only knows natural gas furnaces can create real hazards on a propane system. We don’t send those techs to 95033.
Our Heating & Furnace Services in Los Gatos
Furnace Repair in Los Gatos
Furnace repair in Los Gatos covers everything from failed ignitors on aging Lennox units in 1960s ranch homes to propane pressure faults in mountain properties. The coastal salt air funneling through the mountain gap accelerates corrosion on heat exchangers and blower housings, particularly in systems without factory coatings. We see this in valley-floor homes more than most homeowners expect. A typical furnace repair in Los Gatos runs $150–$700, with most calls completed in a single visit because we stock parts for Trane, Goodman, Rheem, and the other major brands Los Gatos homes commonly run.
Furnace Replacement & Installation
When replacement makes more sense than repair, we size systems for your specific Los Gatos microclimate. A 95032 ranch with original flex ductwork needs different airflow calculations than a hillside custom home with vaulted ceilings. For mountain properties outside PG&E’s natural gas network, we spec propane-ready furnaces with proper LP orifices and manifold pressures — not conversions done aftermarket. We’ve replaced gravity furnaces in downtown bungalows with modern ducted systems, and we’ve installed variable-speed equipment in mountain estates where efficiency expectations run high. Most Los Gatos furnace replacements fall in the $3,800–$7,500 range depending on equipment size and any duct modifications.
Furnace Tune-Up & Seasonal Maintenance
A furnace tune-up in Los Gatos costs $80–$200 and pays for itself in efficiency gains and caught problems. In our climate, we check for salt corrosion on burner assemblies, test flame sensors that foul faster in coastal air, and inspect heat exchangers for stress cracking before heating season demand peaks. For mountain homes, we verify propane regulator function and test high-limit switches — those wildfire ember-resistant vent covers that insurance now requires can restrict return airflow and cause nuisance trips if not accounted for in the system design. We recommend annual service, ideally in October before the first hard freeze hits 95033.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the repair that separates honest technicians from sales-driven ones. In Los Gatos, we find cracked or corroded exchangers more frequently than inland markets because of that salt-laden marine air. A cracked exchanger can leak carbon monoxide. We test with combustion analyzers and visual inspection cameras, and we’ll show you what we find. If replacement is warranted, we quote it. If the furnace is older and the repair approaches replacement cost, we’ll tell you that straight. No ghost stories about “dangerous” equipment to push a sale.
Gas Valve Repair & Propane Conversion
Gas valve work is where our Los Gatos expertise pays off most visibly. Natural gas valves and propane valves are not interchangeable without proper orifice changes and pressure adjustments. On a cold January morning in Aldercroft Heights, we found a propane furnace that wouldn’t fire — the customer’s previous tech had swapped a gas valve without re-jetting the orifices for LP, causing a pressure fault. We fitted a new Goodman LP-converted valve and tested manifold pressure to spec, restoring heat safely. This is not theoretical for us. It’s field work we’ve done.

Trusted Brands We Service in Los Gatos
Your system, our specialty. We service and stock parts for nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Los Gatos specifically, we see a lot of Trane and Lennox in the hillside custom homes, Goodman in the 1970s ranch replacements, and Rheem in the downtown bungalow renovations. We carry common ignitors, gas valves, flame sensors, and blower motors on our trucks, which means most Los Gatos furnace repairs don’t wait for a parts run. That matters when it’s 38 degrees in the mountains and your propane furnace just faulted out.
Common Heating & Furnace Problems We See in Los Gatos Homes
- Propane pressure faults from improper conversions. Furnaces in 95033 that were converted to LP with natural gas orifices still in place run rich, soot up, and can develop flame roll-out. We test manifold pressure on every propane service call because the previous “fix” often created the current problem.
- Corroded heat exchangers from coastal air intrusion. That marine layer pushing through the Los Gatos gap carries salt that attacks uncoated steel. We find this in blower housings and exchanger cells years before expected failure, particularly in systems installed without corrosion-resistant coatings.
- High-limit trips from wildfire vent restrictions. Mountain homes on Summit Road and similar areas now have ember-resistant soffit and gable vents mandated by WUI codes. If the return air path wasn’t recalculated when these went in, the furnace overheats and shuts down on safety. We measure static pressure and modify intake planning to fix this properly.
- Aging flex ductwork in 1960s–70s ranches. The 95032 flatlands are full of these homes with original ductwork that’s cracked, collapsed, or rodent-damaged. The furnace runs fine; the heat never reaches the back bedrooms. We inspect duct integrity on every replacement quote because new equipment on bad ducts wastes money.

FAQs — Heating & Furnace in Los Gatos
Yes. We regularly service propane-fired furnaces in Aldercroft Heights, Summit Road, and other 95033 areas, and we carry LP-specific orifices and gas valves on our trucks. Propane systems require different manifold pressures and conversion procedures than natural gas, and our technicians are trained on both. Call (844) 560-6978 — we’ll confirm your fuel type when you book so we arrive prepared.
Yes, we have several options. High-velocity mini-duct systems use small flexible tubing that fits inside existing walls and ceilings with minimal intrusion. Ductless mini-splits provide zoned heating without any ductwork. For some downtown 95030 homes, we’ve also designed exposed duct systems that work with the Craftsman aesthetic rather than against it. We’ll walk your specific layout and recommend the approach that preserves your home’s character. Free estimates: (844) 560-6978.
The marine air funneling through the Los Gatos gap accelerates corrosion on steel heat exchangers, burner assemblies, and blower housings compared to inland locations like Campbell or south San Jose. We see premature failure in uncoated equipment and recommend annual inspection for rust progression. On replacement jobs, we specify corrosion-resistant coatings and stainless components where the budget allows. If your furnace sits in a garage or crawlspace with outdoor air infiltration, this risk is higher. Call us for an inspection if you’re unsure about your system’s condition.
If you’re in 95033 above 1,500 feet, yes, we recommend low-ambient-rated heat pumps designed to maintain capacity below freezing. Standard heat pumps lose significant output at mountain winter temperatures, and backup electric resistance strips are expensive to run. We’ve installed Daikin and Carrier cold-climate heat pumps in Los Gatos mountain homes that maintain efficiency well below 20°F. For all-electric properties without propane, this is often the best long-term solution. We can evaluate your current system and electrical panel capacity on a free site visit.
Yes, and this is critical: we don’t just swap the furnace and hand you a conversion kit. We size the LP orifices to the specific furnace model, set manifold pressure with a digital manometer, test combustion with an analyzer, and verify safe operation across all firing stages. Improper propane conversion creates sooting, carbon monoxide risk, and equipment damage. We’ve corrected too many “converted” systems that were dangerous.
