We’ve been driving to Los Gatos for 16 years — from the flatland ranch homes off Blossom Hill Road in 95032 to the propane-fueled mountain houses above Lexington Reservoir in 95033. Jason Trent, our owner and Field Supervisor, still rides along on jobs in the Santa Cruz Mountain communities where access roads off Summit Road can turn a 20-minute drive into an hour. That local knowledge matters when your AC quits on a 100°F July afternoon and you need someone who knows which Los Gatos neighborhood they’re heading to, not a dispatcher in another county guessing at the route.
Why Stonegate Heating & Air California Is Los Gatos’s Preferred AC Repair & Installation Company
Los Gatos homeowners have left us nearly 500 verified reviews across platforms, averaging 4.7 stars. That volume comes from showing up, doing the work, and having Jason Trent on-site as Field Supervisor — not just signing checks from a back office. When you hire us, owner-accountable hands touch every phase of the job.
Our technicians know the fuel-source duality that defines Los Gatos HVAC work. Valley-floor homes in 95030 and 95032 connect to PG&E natural gas like any Santa Clara County address. But cross into 95033 — Aldercroft Heights, Chemeketa Park, the communities above the reservoir — and you’re in propane territory. We’ve seen contractors quote standard gas equipment for those mountain addresses, only to discover the mismatch at installation. We confirm fuel type before we quote.
We carry factory training on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever system is in your Los Gatos home, we’ve worked on it. Parts availability for these brands keeps repair turnaround short, even for compressor failures that other companies want to replace whole systems over.
Our AC Repair & Installation Services in Los Gatos
AC Repair
Los Gatos’s thermal edge — where valley heat hits marine fog — creates unique stress patterns. A 95030 home can bake at 102°F while 95033 stays 20 degrees cooler the same afternoon. That temperature swing hard-starts compressors, fries capacitors, and cracks solder joints in refrigerant lines. Our AC Repair & Installation team diagnoses these climate-driven failures fast. Typical repair in Los Gatos: $150–$650.
AC Installation
New installs in Los Gatos require more than square-footage math. Downtown 95030’s pre-WWII Craftsman homes have no original ductwork and tight attics. The 1950s-70s ranches in 95032 have ducts sized for inefficient legacy units. And 95033’s hillside custom builds need multi-zone designs for mixed sun exposure across dramatic grade changes. We size for your specific Los Gatos microclimate, not regional averages. Installation range: $3,500–$7,500.
AC Replacement
Replacement often uncovers compatibility issues unique to Los Gatos. We recently replaced a failing Carrier compressor in a 1950s ranch home on Blossom Hill Road in 95032. The original ductwork was undersized and dated, so we upsized the supply runs and installed a Trane 16 SEER unit to match the home’s cooling load, extending equipment life and improving efficiency. Propane-rated mountain homes need LP-compatible air handlers paired with new condensers. We handle both.
Refrigerant Recharge
Low refrigerant in Los Gatos usually means a leak, not normal consumption. The temperature cycling between hot valley days and cool mountain nights flexes copper lines until they crack at joints. We find and fix the leak before recharging — adding R-410A or R-32 without addressing the source is throwing money away. Recharge typically falls within our $150–$650 repair range.
Capacitor Replacement & Compressor Repair
Capacitors fail fastest in Los Gatos’s startup-heavy conditions — systems cycling on and off as fog rolls in and out. Compressor repair versus replacement depends on age, refrigerant type, and whether your unit is even worth saving. We’ll tell you straight. No upsell.

Common AC Repair & Installation Problems We See in Los Gatos Homes
- Propane-rated system incompatibility in 95033. Mountain homes around Aldercroft Heights and Chemeketa Park rely on LP appliances. Installing standard gas equipment without checking fuel type creates dangerous operation and immediate code failure. We confirm propane tank size and LP ratings before quoting any mountain installation.
- Undersized ducts in 95032 post-war tracts. Ranch homes built in the 1950s-70s have ductwork sized for older, less efficient units. Drop in a modern high-efficiency AC and the restricted airflow causes short-cycling, frozen coils, and premature compressor death. We measure static pressure and upsize runs when the math demands it.
- Inadequate capacity for valley-floor heat. 95030 homes need units sized for 95-102°F peak summer days. Contractors using regional Bay Area averages routinely undersize, leaving Los Gatos homeowners sweating through August afternoons when their “right-sized” unit can’t keep up. We design for your actual thermal load, not a spreadsheet average.
- No-ductwork historic homes in downtown 95030. Original Craftsman and Victorian construction predates forced-air systems entirely. Retrofitting traditional ducted central AC means carving through plaster, dropping soffits, and fighting limited attic clearance. We often recommend ductless mini-split systems that preserve architectural integrity while delivering modern cooling.

FAQs — AC Repair & Installation in Los Gatos
Yes — we regularly install AC systems paired with propane-rated furnaces in Los Gatos’s mountain communities. We’ll verify your propane tank size and confirm LP compatibility for both the air handler and any gas-fired components before quoting. Call (855) 467-1888 to schedule a free estimate.
Usually yes, at least partially. Original 95032 ductwork was sized for older, less efficient units and can’t move enough air for modern systems. We measure static pressure during our assessment and upsize supply runs where the math shows restriction. Sometimes a full replacement isn’t necessary — targeted modifications get the airflow right without tearing out everything. Call (855) 467-1888 for an exact scope and quote.
“Correctly” by whose calculation? Regional sizing averages under-spec cooling for 95030’s 95-102°F peak days. We design for your actual Los Gatos microclimate, not a Santa Clara County average that includes cooler coastal zones. If your unit was sized by a contractor who didn’t account for valley-floor heat intensity, it’s working harder than designed and still falling short. We can assess whether the unit is truly matched to your thermal load.
Ductless mini-split systems are the practical answer for 95030’s pre-WWII homes. We mount compact air handlers on walls or ceilings and run refrigerant lines through minimal penetrations — no soffits, no plaster demolition, no fighting 18-inch attics. You get zoned cooling with modern efficiency and keep your home’s original character intact. Call (855) 467-1888 to see layout options for your specific floor plan.
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our recommendation depends on your home’s fuel type, duct configuration, and cooling load — not on pushing a particular brand. For Los Gatos’s varied housing stock, that flexibility matters. Call (855) 467-1888 to discuss which system fits your situation.
