HVAC Company in Calistoga, CA
Calistoga runs hotter than anywhere else in the Bay Area, and homes here were rarely built for that heat. Meadowsweet Heating & Air handles AC repair, furnace repair, and AC installation across Calistoga, which means working around Victorian cottages with no original ductwork, hillside estates with wall-to-wall glass, and a geothermal field that changes how equipment performs underground. Every job starts with a written price before any work begins, and a live person answers our phone around the clock. Call (747) 966-3037 when your system stops keeping up.
Why Calistoga Homes Are Different
Two things set Calistoga apart from every other Napa Valley town, and both of them change how HVAC work gets done here.
First, the heat. Calistoga sits in a narrow valley bowl walled in by the Palisades and Mayacamas mountains, far enough north and inland that the Pacific marine layer never reaches it. Summer days at 105°F to 110°F are not rare here, and heat loads run measurably higher than systems spec’d for Napa or St. Helena just 15 miles south. A unit sized for Santa Rosa will not hold Calistoga’s peak afternoons. Second, the geothermal field. The same subsurface system that feeds the hot springs and the Old Faithful Geyser keeps ground temperatures under the historic district warmer than standard California assumptions. Crawl-space and sub-slab ducts near Lincoln Avenue pick up extra heat year-round, and equipment installed low in those spaces runs hotter than its spec sheet assumes. A technician who uses book-standard ground-temperature numbers will under-size cooling capacity. Add in the housing stock: late-19th and early-20th century cottages and spa buildings with no original ductwork, alongside newer wine-country homes with open great rooms, exposed beams, and big glazing that pushes cooling demand up. Calistoga HVAC work is a different job than it is anywhere else in the valley.
Our Main Calistoga Services
Most Calistoga calls to us fall into three categories: getting a struggling air conditioner through a 100°F week, getting a furnace ready for a near-freezing winter night, and replacing equipment that the local climate has simply outworked. Each service has its own page with local details and pricing.
AC Repair in Calistoga
When your air conditioner fails during a Calistoga heat event, the house warms up fast, and the fix usually comes down to diagnosing why the system can’t shed the valley’s heat load. We work on equipment from nine major brands, and we diagnose against real local conditions: short cycling from undersized condensers, refrigerant charge drift from extreme temperature swings, and geothermal heat gain in crawl-space linesets. Our technicians show up with shoe covers, lay down drop cloths, and give you a written price before any work starts. See typical Calistoga repair ranges on the AC Repair in Calistoga page.

Furnace Repair in Calistoga
Calistoga winter nights dip near or below freezing, and the same older homes that overheat in summer lose heat fast after dark. Furnace repair here means working in tight historic-home basements and crawl spaces, testing heat exchangers in equipment that sat idle through long hot seasons, and checking for dust and debris buildup from dry summer months. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. The Furnace Repair in Calistoga page covers what a Calistoga furnace call typically costs.

AC Installation in Calistoga
New AC installation in Calistoga is a load-calculation job before it is an equipment job. Older cottages often need ductless mini-splits because there is no space for ductwork; newer hillside homes need heavier capacity for their glazing and open floor plans. We size to Calistoga’s triple-digit reality, not to a generic California baseline, and we put a written fixed price in front of you before ordering anything. Rebate and financing paperwork is handled on our side. The AC Installation in Calistoga page walks through the process and the price.

Pricing for HVAC Company in Calistoga, CA
These are the price ranges Calistoga homeowners should expect for common HVAC work. A written price is confirmed before any work starts, always.
| Service | Typical range in Calistoga |
|---|---|
| AC diagnostic and minor repair | $150-$350 |
| AC repair with parts (capacitor, contactor, fan motor) | $250-$650 |
| Furnace diagnostic and minor repair | $150-$350 |

| AC installation, high efficiency or heat pump | $5,000-$7,500 |
| Seasonal tune-up, AC or furnace | $80-$200 |
Two Calistoga-specific factors push prices within these ranges: geothermal ground heat under the historic district means some crawl-space work takes longer and needs more insulation correction, and the valley’s extreme summer design temperature means we size equipment upward, which can move an install toward the higher end of its band. Whatever the number, it is written down and agreed to before we start.

What Calistoga Customers Say
"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke
