Los Gatos isn’t one market. It’s three. Downtown’s 95030 Craftsman bungalows with no ductwork and six-inch attics. The 95032 flatlands of postwar ranches with sagging flex runs. And the 95033 Santa Cruz Mountain communities above Lexington Reservoir, where PG&E’s gas lines stop and propane tanks sit beside cedar-shingled custom homes. We’ve worked all three. That split — electric and propane, flatland and hillside, pre-war and new construction — shapes every heat pump and mini-split job we take in Los Gatos.
Why Stonegate Heating & Air California Is Los Gatos’s Preferred Heat Pump & Mini Split Company
We’ve earned 499 verified reviews at a 4.7-star average across our 16 years in California HVAC. Los Gatos homeowners find us after the franchise tech shrugs at their Carrier multi-zone or their Lennox cold-climate unit and says “we don’t service that brand.” We do. Nine of them. Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, American Standard — whatever sits in your mechanical room or hangs on your exterior wall, our technicians have factory training or field hours on it.
Owner Jason Trent holds the title of Field Supervisor, not just Owner. That means he’s on job sites, not in a back office. In Los Gatos, that matters because the 95033 mountain calls aren’t routine. Narrow access roads off Summit Road can add 30–40 minutes each way. Jason supervises the load calculations for hillside homes with mixed sun exposures and dramatic grade changes. He confirms propane tank size before any 95033 quote. A passive owner can’t do that.
Our review volume — nearly 500 — reflects repeatable results across real jobs, not cherry-picked testimonials. Los Gatos customers mention our upfront pricing, our willingness to explain why a ductless system beats a ducted retrofit in a 1920s bungalow, and the fact that we don’t send a different face every time.
Our Heat Pump & Mini Split Services in Los Gatos
Heat Pump Repair in Los Gatos
Los Gatos heat pumps fail in patterns tied to elevation. On the 95030 valley floor, we see refrigerant leaks from mini-split line sets routed through uninsulated pre-WWII attics — the original lath-and-plaster ceiling cavities freeze hard during January cold snaps. In 95033, propane-compatible heat pumps lose heating capacity when tank pressure drops below 20%. That’s a failure mode that doesn’t exist in Campbell or Saratoga, where natural gas flows to every address. We test for both. Our repair calls start at $150 and run to $650 depending on refrigerant recovery, part replacement, or electrical diagnosis.
Heat Pump Installation in Los Gatos
New heat pump installs in Los Gatos demand elevation-specific sizing. A 95030 home at 400 feet elevation faces 95–102°F summer peaks and mild winters; a 95033 home at 1,800 feet runs 15–20°F cooler on the same August afternoon but sees measurable frost and higher heating degree-days from November through March. Regional average load calculations routinely under-spec heating for the upper elevations. We run Manual J calculations for each Los Gatos address, accounting for marine fog penetration, hillside exposure, and whether the home sits beyond PG&E’s gas grid. Standard electric systems work in 95030 and 95032. Propane-compatible or pure electric cold-climate heat pumps serve 95033.
Mini Split Installation in Los Gatos
Ductless mini-split installation is our most requested service in downtown Los Gatos. The 95030 housing stock — Craftsman, Victorian, early California bungalows built before 1940 — has no original ductwork and attic clearance measured in inches, not feet. Traditional forced-air retrofits mean dropping soffits, sacrificing headroom, or abandoning the project. Mini splits solve this. We mount the outdoor condenser on a concrete pad or wall bracket, run refrigerant lines through exterior walls or crawlspaces, and place indoor heads where they’ll serve living zones without tearing into historic plaster. In 95032 ranch homes, we use mini splits to supplement aging undersized duct runs or to condition additions the original furnace never reached.
Mini Split Repair in Los Gatos
Los Gatos mini-split repairs range from $150 for a clogged condensate pump to $650 for compressor or board replacement. The 95033 hillside homes suffer undersized or blocked condensate drains that back up during heavy winter rain and mountain fog — water damage follows. We clear drains, resize lines where grade changes create pooling, and install safety switches that shut the unit before overflow. In 95030’s legacy housing, we find line sets pierced by decades of amateur electrical and plumbing work hidden in walls. Our technicians carry brazing gear, nitrogen purge equipment, and refrigerant matched to Daikin, Carrier, and Mitsubishi systems common in the area.
Multi-Zone Systems for Los Gatos
Multi-zone ductless systems dominate our 95033 hillside custom builds. These homes sprawl across grades with mixed sun exposures — a great room facing south catches afternoon bake, while a north-facing guest wing stays shaded and cool. A single thermostat can’t manage that. We design multi-zone systems with individual heads per zone, each with its own temperature target. In one Chemeketa Park install, we paired a Daikin outdoor unit with five indoor heads across three levels, running supply lines through a crawlspace that added time to the job but preserved the home’s cedar interior. The propane tank was only 120 gallons, so we sized a cold-climate heat pump that handles mountain heating loads without relying on costly LP deliveries.
Ductless Systems for Los Gatos’s Older Housing
Ductless isn’t a compromise in Los Gatos. It’s often the only practical path. The 95030 pre-WWII stock has plaster walls, minimal attic space, and no chase routes for ductwork. Even if you could force ducts through, you’d destroy historic character and still deliver conditioned air through leaky flex in unconditioned cavities. Ductless mini splits deliver heated or cooled air directly to each room through a three-inch hole in the exterior wall. No soffits. No attic crawling. No 80-year-old plaster demolition. We’ve completed dozens of these retrofits in Los Gatos, and the feedback is consistent: should have done this years ago.

Trusted Brands We Service in Los Gatos
We maintain active technical fluency on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Gatos, that means we don’t turn away jobs because of badge color. We stock common mini-split parts — compressors, boards, expansion valves, condensate pumps — for faster turnaround on 95030 and 95032 repairs. For 95033’s propane-compatible and cold-climate equipment, we source through California distributors with mountain-HVAC experience. Jason Trent reviews every major install personally, confirming that brand-specific startup procedures and charging protocols are followed exactly. A Goodman heat pump and a Daikin mini split don’t speak the same language. Our technicians are fluent in both.
Common Heat Pump & Mini Split Problems We See in Los Gatos Homes
- Undersized condensate drains in 95033 hillside homes. Mountain fog and winter rain overwhelm drains designed for dry valley conditions. Water backs into walls and crawlspaces before homeowners notice. We resize drains and install float switches on every 95033 mini split we service.
- Frozen line sets in 95030’s uninsulated pre-WWII attics. Refrigerant lines routed through lath-and-plaster ceiling cavities hit hard freeze in January. Insulation sleeves help, but often the real fix is rerouting through exterior walls or conditioned basement spaces.
- Propane pressure drop in 95033 heat pumps. When tank levels fall below 20%, vapor pressure can’t maintain heating capacity. The heat pump labors, efficiency collapses, and the homeowner calls thinking the unit failed. We check tank gauges first.
- Retrofit ductwork in 95032 ranches that’s too small for heat pump air volumes. Original 1950s–1970s flex runs were sized for gas furnaces with higher temperature rise and lower airflow. Heat pumps need more air across the coil. The ductwork whistles, rooms don’t reach setpoint, and the compressor short-cycles. Mini splits bypass the problem entirely.
Pricing for Heat Pump & Mini Split in Los Gatos, CA
Here’s what Los Gatos homeowners actually pay:
| Service | Price Range |
|---|---|
| Mini Split Repair | $150–$650 |
| Mini Split Install | $3,500–$7,500 |
Install costs swing with zone count, line-set length, electrical upgrades, and whether we’re mounting on stucco, wood siding, or a concrete pad. A single-zone 12K BTU mini split in a 95030 bungalow runs toward the lower end. A four-zone cold-climate system for a 95033 hillside custom home with complex refrigerant runs and propane compatibility requirements pushes higher. We don’t quote blind. Every Los Gatos estimate starts with a site visit, load calculation, and honest assessment of whether repair, retrofit, or full replacement makes sense. Estimates are free. Call (855) 467-1888 to schedule.
We Also Serve Cities Near Los Gatos
Our service radius covers Saratoga’s estate properties, Campbell’s denser residential blocks, the Communications Hill developments, and Cupertino’s tech-corridor homes. Each has its own HVAC character — Saratoga’s large lots and pool houses, Campbell’s tighter access and smaller systems. We adjust accordingly. The fuel-source duality of Los Gatos’s 95033 mountain communities, though, that’s unique to this town. Neighboring cities don’t split between propane and natural gas across a 1,500-foot elevation gain.

FAQs — Heat Pump & Mini Split in Los Gatos
Yes, but the equipment must be specifically rated for propane compatibility, and the propane tank must be sized to maintain adequate vapor pressure in cold weather. Most 95033 homes we serve use pure electric cold-climate heat pumps instead, eliminating propane dependency entirely. Call (855) 467-1888 and we’ll evaluate your tank size, electrical panel, and heating load to recommend the cleaner path.
They probably are. Pre-WWII Los Gatos homes in 95030 were built for gravity furnaces or early forced-air systems with much lower airflow requirements than modern heat pumps. The original ductwork, if it exists at all, can’t move the volume a heat pump needs across its coil. Mini splits bypass this by delivering conditioned air directly to each room without ducts. We assess existing duct capacity on every 95030 heat pump consultation and recommend ductless when the math doesn’t work.
It means a heat pump sized for valley floor cooling will overcool the mountain, and one sized for mountain heating will underperform on the valley’s hottest days. Los Gatos requires elevation-specific Manual J calculations, not regional average tables. We’ve seen 95033 homes where the previous contractor used San Jose load data and the homeowner froze through January. We don’t do that. Jason Trent verifies every calculation personally.
They’re often the only system that does. A mini split needs a three-inch hole through an exterior wall for refrigerant lines, power, and drain. No attic. No soffits. No demolition of 1920s plaster. We’ve installed dozens in 95030’s Craftsman and Victorian stock, mounting outdoor units on side yards or rear patios where they’re hidden from street view. The indoor heads sit high on walls, clear of period trim and built-ins.
Daikin and Carrier lead our 95033 multi-zone installations for cold-climate performance and part availability in California. Daikin’s multi-split outdoor units pair with up to eight indoor styles — wall mounts, floor consoles, concealed ducted units — which matters in custom homes where each zone has different architectural constraints. Carrier’s Infinity series offers similar flexibility with strong local dealer support. We don’t push one brand. We match equipment to your home’s heating load, electrical service, propane situation if applicable, and your preference for wall versus concealed installation. Call (855) 467-1888 for a brand-neutral assessment.
