When a propane furnace quits on a cold morning in Los Altos Hills, the fix rarely looks like the one next door. Big custom homes on acre-plus lots, many of them built between the 1960s and 1980s, hold heating and cooling systems that were designed for a specific house, not a standard plan. That shapes furnace repair here more than anything else: propane, electric and heat pump systems, long duct runs, and equipment tucked into an attic or a rear closet. We handle furnace repair, cooling and replacement work across nine major brands. Call (888) 870-1847 and we’ll get a technician out to look at it.
Why Los Altos Hills Homes Are Different
Los Altos Hills sits in the inland foothills just west of the bay, and that position changes the load on your HVAC system. Summer afternoons run warmer here than on the Peninsula flats, then the nights cool off, so a house needs real cooling capacity and working heat in the same week. Many parcels have no gas main, so heating comes from propane-fired furnaces, electric resistance or a heat pump. Smoke season adds another layer: filtration and ventilation matter as much as temperature.
The housing stock is mostly custom. Homes of 3,000 to 8,000+ square feet sit on one-acre-plus lots with vaulted ceilings, extensive glazing and zoned multi-system layouts. Detached guest houses, pool houses and wine rooms often carry their own conditioning. On the steep, wooded parcels off winding lanes like Elena or La Cuesta, technicians regularly find condenser pads perched on graded terraces or cantilevered decks, with line sets running past 100 feet. Access, refrigerant charge and static pressure become the real constraints of the job, not the equipment nameplate.

Our Main Los Altos Hills Services
Two jobs bring Los Altos Hills homeowners to the phone most often: cooling that quits on a hot afternoon and heat that fails on a cold morning. Both fall under the same set of technicians.
AC Repair in Los Altos Hills
Cooling calls in Los Altos Hills tend to be diagnostic puzzles rather than simple part swaps. A system serving a 5,000-square-foot hillside house with big south-facing glass may be correctly sized and still struggle because a line set runs 120 feet to a pad on a lower terrace, or because return air is choked. We check refrigerant charge, static pressure and airflow before we recommend anything. If your system is a Carrier, Trane or Lennox, it’s equipment we see regularly. For a full breakdown of what we handle, see AC Repair in Los Altos Hills.
AC Installation in Los Altos Hills
Replacement here starts with a load calculation, not a catalog. A custom home with zoned systems and extensive glazing needs equipment sized to the actual room-by-room load, and the line-set route across a graded lot often decides where the new condenser can sit. We work with American Standard, Carrier and Trane among others, so the recommendation fits your existing setup and budget. You get a written fixed price and a set install date. Details are on our AC Installation in Los Altos Hills page.
Furnace Repair in Los Altos Hills
Furnace repair in Los Altos Hills usually means one of two systems: a propane-fired furnace in a home without gas main service, or a heat pump handling both heating and cooling. Many of these houses went up between the 1960s and 1980s and have been rebuilt or added onto since, so the heating equipment is often a mix of eras and zones. Winter mornings here are cold enough that a failed furnace is urgent, and the long duct runs in a sprawling custom home can leave far rooms short of heat even when the unit runs. Our Furnace Repair technicians have up to 10 years of experience with these systems.
Gas Furnace Repair
Signs you need it
You smell gas near the unit, hear a delayed or booming ignition, see a yellow rather than blue flame, or the furnace short-cycles and never reaches temperature.
What it costs in Los Altos Hills
Most gas furnace repairs here fall in the typical estimated range of $150 to $700, and the written estimate sets the final price.
How we do it
We shut off the gas supply, test the igniter, flame sensor and pressure switch, inspect the heat exchanger for cracks, and confirm combustion air before restarting the unit and checking the temperature rise.
Heat Pump Repair
Signs you need it
The system blows cool air in heating mode, the outdoor unit ices over and stays that way, or you hear the reversing valve clunk without any change in temperature.
What it costs in Los Altos Hills
Heat pump repairs typically run $150 to $700 estimated, with refrigerant work and long line sets pushing toward the upper end.
How we do it
We check refrigerant charge against the actual line-set length, test the reversing valve and defrost board, verify auxiliary heat staging, and measure supply and return temperatures at the air handler.
What Furnace Repair Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Diagnostic visit and simple component repair | $150 – $350 |
| Igniter, flame sensor or pressure switch replacement | $250 – $500 |
| Blower motor, control board or heat pump component repair | $400 – $700 |
A propane system, a heat pump with a long line set, or a zoned setup with several air handlers all add labor compared with a straightforward gas furnace in a tract home. We give you a written price before any work starts, and the estimate is free.
Can you repair a propane furnace in Los Altos Hills?
Yes. Many Los Altos Hills parcels have no gas main, so propane furnaces are common here. We check the tank-side regulator, gas pressure at the valve, burner operation and venting, and we flag any combustion or carbon monoxide concern before we leave.
How long does furnace repair take in Los Altos Hills?
Most repairs are finished in a single visit when the part is a standard igniter, sensor or control board. Equipment in a tight attic or a rear closet on a steep lot can add access time, so we confirm scope with you first. Call (888) 870-1847 for an exact quote.
Brands We Service in Los Altos Hills
Our technicians are factory-familiar with nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant and American Standard. That range covers both premium systems and value-tier equipment, so a diagnosis doesn’t stall because the nameplate is unfamiliar. We don’t claim parts on hand, but knowing the brand shortens turnaround on the visit. See our brands for the full list.

What Los Altos Hills Customers Say
"Ductwork in the attic had a disconnected run that had been dumping cold air into the insulation for who knows how long. He found it, resealed it, and one bedroom that was always hot is now normal."
- Daniela Salazar"Work was done properly. I did have to follow up twice to get the invoice and the warranty info emailed over. The repair itself has been trouble free."
- Angela Yang"New system install, two days, and they were careful with the floors and the attic access the entire time. Registered the warranty for me and emailed the paperwork."
