AfterHVAC Company in Alpine, CA
Coldharbour Heating & Air handles HVAC work in Alpine, CA where the elevation and terrain create demands most San Diego County contractors rarely face. At 1,700-2,200 feet in the Peninsular Ranges foothills, Alpine homes need systems built for hard freezes, occasional snow, and summer days past 100°F, often within the same year. We dispatch crews from our San Diego office and carry parts for Trane, Lennox, Goodman, and Rheem systems so most repairs finish in a single trip. Call (817) 402-2972 and a live person answers, 24 hours a day.
Why Alpine Homes Are Different
Alpine’s housing stock is mostly 1960s-1980s ranch and split-level homes on large unincorporated lots, many still running original ductwork and attic insulation that was never meant for real winter cold. That older metal ductwork contracts in freezing nights and expands in summer heat, creating leaks that waste energy year-round. Many properties also rely on propane rather than natural gas, since SoCalGas service is limited here, so heating equipment must be propane-rated and tank logistics planned into every install.
The Very High Fire Hazard Severity Zone designation means ignition-resistant construction standards apply, and during Red Flag Warnings the Santa Ana winds can force wildfire smoke straight through outdoor-air intakes into living spaces. We’ve learned to spec filtered intake assemblies and program smart thermostats to default recirculation mode when the county issues those warnings. Permits for HVAC work in unincorporated Alpine run through the San Diego County Department of Planning and Development, not a city office, and turnaround times vary seasonally.
Our Main Alpine Services
These are the three jobs Alpine homeowners call us about most often, each with its own dedicated page.
AC Repair in Alpine
When an AC quits during a Santa Ana event in Alpine, the indoor temperature can climb fast. We carry capacitors, contactors, and refrigerant for systems from Trane, Lennox, Goodman, and Rheem, and we know the common failure points in units that have cycled hard through both summer heat and winter freeze-thaw stress. Our technician will hand you a written price before opening any toolbox, and every repair carries the 365-Day Done Right Promise. AC Repair in Alpine
Furnace Repair in Alpine
Alpine’s overnight lows below freezing from November through March put real load on furnaces, especially propane-fired units that many homeowners here depend on. Igniter failures, pressure switch faults, and cracked heat exchangers are the calls we see most when temperatures drop. We stock igniters and flame sensors for major brands, and we’ll check propane regulator pressure as part of every heating call because low pressure mimics other failures. Furnace Repair in Alpine
AC Installation in Alpine
New AC installation in Alpine requires proper load calculation for genuine dual-season demand, not the cooling-only sizing common closer to the coast. We factor elevation, solar exposure on large lots, and existing ductwork condition, then spec equipment that handles 100°F summer afternoons and doesn’t short-cycle in milder weather. Installations are scheduled, not same-day, with a fixed written price and all rebate paperwork handled. AC Installation in Alpine

What Alpine Customers Say
"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
