AfterHVAC Company in Calistoga, CA
Calistoga sits at the top of the Napa Valley, where summer days regularly cross 100°F and winter nights drop into the 30s. The homes here range from 1940s bungalows off Foothill Boulevard to newer builds on the east side, and almost all of them lean hard on their cooling and heating for months at a time. We’re the HVAC company Calistoga homeowners call when a system quits on a Friday afternoon in July or the furnace won’t fire on a January morning. Call (361) 306-9515 and a live person answers, 24/7.
Why Calistoga Homes Are Different
Calistoga’s combination of hot, dry summers and cool, damp winters pushes HVAC equipment harder than most Bay Area locations. The diurnal swing is real: a system that ran full-blast through a 103° afternoon gets a 55° night, and that thermal cycling shortens capacitor and contactor life. Homes near the Silverado Trail see more dust and pollen from vineyard work, which means filters clog faster and outdoor coils need more frequent attention. Older Calistoga homes often have undersized ductwork that was fine for a wall furnace but struggles with a modern heat pump, so we check static pressure and airflow on every call, not just refrigerant level. Homes up on the hillsides off Diamond Mountain Road face steeper access and more run time for the same square footage. If the home is on a well, we also check for hard water scale on evaporator coils, a common Calistoga issue that quietly kills efficiency.
Our Main Calistoga Services
Most calls we run in Calistoga come down to two things: the AC won’t cool, or the furnace won’t heat. Each has its own Calistoga page with full pricing, what the fix covers, and what to expect on the day of the job.
AC Repair in Calistoga
Calistoga AC failures are usually one of four things: a failed capacitor, low refrigerant from a slow leak, a plugged condensate line, or a worn contactor. We diagnose by testing, not by guess, and the price goes in writing before any work starts. On a 105° day, we run calls from early morning into the evening and a live person answers the phone the whole time. See AC Repair in Calistoga for the full breakdown of what repairs typically cost and how fast we can get out.
Heat Pump Installation in Calistoga
Heat pumps make particular sense in Calistoga because the winter is mild enough that a properly sized unit handles heating without backup strips, and the summer cooling load is where the real work happens. We size by Manual J, not by square foot, and we write the full installed price before ordering equipment. Heat Pump Installation in Calistoga walks through equipment options, rebates, and what installation day looks like.
Furnace Repair in Calistoga
When a Calistoga furnace won’t light or cycles on and off, the cause is most often a failed igniter, a dirty flame sensor, or a safety switch that’s doing its job. We test the full sequence of operation, show you what failed, and quote the repair in writing before we touch a part. Every repair carries a one-year written guarantee. Full details are on Furnace Repair in Calistoga.

FAQs About HVAC Company in Calistoga
Same-day for cooling failures in summer heat, usually within a few hours. Furnace calls outside a cold snap are typically next-morning. Call (361) 306-9515 and we’ll give you a straight answer on timing before you hang up.
Yes. Replacement of a furnace, AC, or heat pump in Calistoga requires a permit through the city, and the trade needs a licensed contractor. We pull the permit for you and schedule the inspection as part of the install. Calistoga enforces this, so if someone offers to skip permitting, treat that as a red flag.
Most Calistoga HOAs have rules about visible equipment placement and noise levels. We coordinate with the HOA before installation day when needed and submit whatever documentation they require. This is standard for hillside homes and the newer developments off Foothill.
