We’ve been driving our Heating & Furnace trucks up the winding roads of Los Altos Hills for nearly two decades. From the fog-laced canyons off Page Mill Road to the sun-exposed ridges above Elena Road, we know the microclimates here create heating problems that flatland contractors miss. Los Altos Hills sits at 200–600+ feet in the Santa Cruz Mountain foothills, and that elevation swing means your furnace might be fighting salt-laden Pacific moisture in a cramped crawl space while your neighbor three streets over bakes in dry heat. We’re Marcus Feldman and the Crestview team — owner-managed, not outsourced — and we show up with Manual J load calculators, duct blasters, and the patience to trace ductwork through hillside chases that weren’t designed for easy access.
Why Crestview Heating & Air California Is Los Altos Hills’s Preferred Heating & Furnace Company
Our reputation in Los Altos Hills was built one hillside home at a time. The 250+ customers who left reviews agree — we’ve earned a 4.8-star average — and a growing share of those reviews come from 94022 addresses where homeowners were tired of technicians who treated their multi-zone system like a standard tract-home install.
Owner Marcus Feldman also serves as Service Manager, which means the person answering your questions on the phone is the same person who’ll review your load calculation and sign off on the final walkthrough. No dispatch center. No rotating subcontractors who need a map to find Robleda Road.
Response time to Los Altos Hills is typically same-day for calls received before noon, next-day for afternoon requests. Emergency HVAC service is available when systems fail outside normal hours — and in January, when ridge-top temperatures drop into the 30s and canyon homes hit the 20s, those calls matter.
We know the local building stock: custom homes from the late 1950s through the 2000s, split-level and cantilevered into hillsides, original forced-air or radiant systems now 30–50 years old. That knowledge changes how we diagnose. A technician who assumes standard duct routing will waste hours looking for access panels that don’t exist.
Our Heating & Furnace Services in Los Altos Hills
Furnace Repair
Furnace repair in Los Altos Hills starts at $150 and runs to $700 for complex multi-zone diagnostics. The most common call we get? An oversized original furnace short-cycling because it’s trying to heat 3,500 sq ft with a single thermostat while half the conditioned air leaks into a hillside crawl space. We don’t just swap parts. We measure duct leakage, check combustion analysis, and verify whether your 1960s burner assembly is corroded from decades of Pacific moisture exposure.
Furnace Replacement
Replacing a furnace in Los Altos Hills is rarely a simple swap. Mandatory 1-acre minimum lot sizes here mean virtually every job serves a large custom home requiring multi-zone forced-air or hydronic radiant systems — a stark contrast to the tract-home markets of neighboring Los Altos and Mountain View. We size every replacement with a site-specific Manual J calculation, accounting for your exact elevation, solar exposure, and whether you’re ridge-top or canyon-facing. Brand options include Trane, Lennox, and Rheem units with corrosion-resistant heat exchangers suited to salt-air environments.
Furnace Tune-Up
A furnace tune-up in Los Altos Hills costs $80–$200 and takes 60–90 minutes. For hillside homes, this isn’t a quick filter swap. We inspect burner assemblies for salt corrosion, test heat exchangers for cracks caused by decades of cycling in damp crawl spaces, and measure duct leakage in those unconditioned hillside chases where 25–35% of your heated air routinely escapes. We recently serviced a 4,500 sq ft mid-century ranch on Elena Road where the 45-year-old gas furnace had a cracked heat exchanger from decades of cycling in a fog-drenched crawl space. We replaced it with a two-stage Carrier unit, re-routed the ductwork through the steep grade, and sealed 30% leakage found during our duct test.
Heat Exchanger Inspection & Replacement
Heat exchanger failure in Los Altos Hills accelerates compared to inland cities. Salt-air corrosion from Pacific moisture attacks burner assemblies and heat exchangers in furnaces vented through side walls, especially on canyon-facing properties that never fully dry out. We use combustion analyzers and borescope cameras to inspect for cracks — a cracked exchanger means carbon monoxide risk and immediate replacement. If your furnace is 25+ years old and you’re in a fog-exposed zone, we recommend annual heat exchanger checks.

Trusted Brands We Service in Los Altos Hills
Your system, our specialty. We service and stock parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Altos Hills customers, we keep Trane and Rheem heat exchanger assemblies and Lennox burner kits on our trucks because salt-air corrosion makes these the most common failure points in coastal-exposed hillside homes. Factory-trained compatibility means you’re never told “we don’t work on that.” From emergency calls to commercial buildouts, if it heats air or water in Los Altos Hills, we’ve likely repaired it.
Common Heating & Furnace Problems We See in Los Altos Hills Homes
- Salt-air corrosion of burner assemblies. Pacific moisture drawn into canyon-facing crawl spaces corrodes gas burner orifices and heat exchanger seams years faster than in San Jose or Sunnyvale. We see this most on homes below 400 feet elevation on the western slopes.
- Oversized furnaces short-cycling from poor zoning. Original 1960s–70s gas furnaces were sized for “heat the whole house” with one thermostat. In 4,000+ sq ft split-levels, that means constant on-off cycling, premature ignitor wear, and gas valve failure every 3–5 years.
- Massive duct leakage in hillside crawl spaces. Duct systems routed through unconditioned, steep-slope crawl spaces leak 25–35% of delivered capacity. The furnace runs longer, parts wear faster, and upstairs rooms never reach temperature.
- Heat exchanger cracks from decades of damp cycling. Fog-drenched crawl spaces keep furnaces in condensing conditions they weren’t designed for. We find cracked exchangers in 40+ year systems at roughly twice the rate we see in dry, flatland markets.
Pricing for Heating & Furnace in Los Altos Hills, CA
Here’s what heating and furnace service costs in the Los Altos Hills market. These ranges reflect the complexity of hillside homes — longer duct runs, difficult access, and multi-zone diagnostics:
| Service | Price Range |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Tune-Up | $80 – $200 |
| Heat Exchanger Inspection | Included in tune-up; replacement quoted after diagnosis |
| Ignitor Replacement | Quoted after diagnosis |
| Gas Valve Repair | Quoted after diagnosis |
| Furnace Replacement | Quoted after on-site Manual J and zone design |
What moves you within these ranges? Access difficulty (steep hillside crawl spaces take longer), number of zones, and whether we find duct leakage that needs sealing before equipment will perform. We provide upfront pricing after diagnosis — no surprises, just the actual cost to fix your specific system. Call (844) 560-6978 for a free estimate.

FAQs — Heating & Furnace in Los Altos Hills
Salt-air corrosion from Pacific moisture accelerates failure of burner assemblies and heat exchangers in furnaces vented through side walls, especially in canyon-facing homes below 400 feet elevation that sit in persistent fog. Inland cities like San Jose see drier conditions and slower corrosion rates. If your furnace is 20+ years old and west-facing, we recommend annual heat exchanger inspection with a combustion analyzer. Call (844) 560-6978 to schedule — estimates are free.
The fix is usually a combination of duct sealing and zone redesign, not a bigger furnace. Original duct systems in these hillside homes leak 25–35% of heated air into unconditioned crawl spaces, and single-zone thermostats can’t overcome that loss across 3,500+ sq ft. We start with a duct blaster test to measure leakage, then seal and insulate accessible runs. If the existing furnace is oversized and short-cycling, we may recommend right-sizing with a multi-stage replacement. Call (844) 560-6978 for a free assessment.
Yes. A hillside tune-up in Los Altos Hills includes corrosion inspection of burner assemblies and heat exchangers, duct leakage measurement, and combustion analysis in conditions that flatland technicians rarely encounter. The fog-drenched crawl spaces here create condensing environments that standard checklists don’t address. Our tune-ups take 60–90 minutes versus the 30-minute quick-cleans common elsewhere. Call (844) 560-6978 to book — tune-ups are $80–$200.
Trane and Rheem both offer heat exchanger designs with enhanced corrosion resistance that perform well in salt-air exposure, and Lennox has burner assembly coatings suited to damp environments. The “best” brand depends on your existing duct configuration, zoning needs, and whether you’re ridge-top dry or canyon-facing damp. We stock parts for all nine major brands and won’t push a one-size-fits-all solution. Call (844) 560-6978 for a brand-specific recommendation after seeing your system.
Repeated gas valve failure usually signals an oversized furnace short-cycling due to poor zoning — the valve opens and closes hundreds of extra times per season, wearing out its solenoid. This is common in 1960s–70s Los Altos Hills custom homes where original furnaces were never designed for multi-zone control. Replacing the valve without fixing the cycling pattern wastes your money. We diagnose root cause with combustion analysis and runtime data, then recommend either zoning upgrades or right-sized replacement. Call (844) 560-6978 for a permanent fix — estimates are free.
