AfterHVAC Company in Napa, CA
Dalton Heating & Air is the HVAC company in Napa that puts the price in writing before any work starts. Napa’s mix of 1950s ranchers, hillside contemporaries, and wine-country estates means no two systems fail the same way, and the summer heat pushing through the valley doesn’t forgive a weak AC. If your air conditioning quit or your furnace is making noise it shouldn’t, call (361) 306-9515 and a live person answers, any hour.
Why Napa Homes Are Different
Napa sits in a valley that traps heat. July and August regularly push into the 90s, and homes in Browns Valley and the east side take the brunt of the afternoon sun. That heat load is the reason AC systems in Napa age harder than the same equipment in coastal towns 30 miles west. Compressors run longer, capacitors burn out faster, and condensate lines clog more often as the system cycles continuously through the hottest weeks.
The housing stock adds another layer. A 1960s rancher off Jefferson Street has different ductwork, different insulation, and a different electrical panel than a newer build in Vintage Ranch. Older homes often have undersized returns and original duct runs that were never designed for modern equipment. When we size a heat pump or diagnose airflow problems in Napa, we’re looking at the house itself, not just the unit outside. Terrain matters too – homes up in the western hills or along Dry Creek Road sit in microclimates where mornings stay cool but afternoons spike, and systems cycle harder as a result.
Our Main Napa Services
Napa homeowners call Dalton Heating & Air most often for these three jobs. Each has its own page with local pricing, what the work involves, and what to expect when a technician arrives.
AC Repair in Napa
When an air conditioner fails during a Napa heat wave, the fix usually comes down to a capacitor, a contactor, a refrigerant leak, or a failed compressor. We diagnose the exact fault, put the repair cost in writing before touching anything, and guarantee it in writing for a full year. Most AC repair in Napa calls are completed the same day, and if the repair fails within the guarantee period, we return at no charge. That’s the Garrison Standard, and it applies to every call.
Heat Pump Installation in Napa
A heat pump handles both cooling and heating, which fits Napa’s climate well – hot summers and cool, damp winters. The job means sizing the unit to the home’s actual heat load and ductwork, not swapping a box for a box. Heat pump installation in Napa is load-calculated, given a written fixed price, and scheduled on a set date. We handle the permits, the electrical, and the line-set work, so the system runs efficiently from day one.
Furnace Repair in Napa
Napa winters dip into the 30s and 40s, and an old furnace that won’t ignite or a heat exchanger that cracked is a real problem. Furnace repair in Napa covers failed igniters, bad gas valves, failing draft motors, and control board faults. We service all major furnace brands and finish most repairs in a single visit. The price is in writing before the part goes in, and the repair is guaranteed in writing for one full year.

Brands We Service in Napa
Our technicians are factory-trained to service nine major residential HVAC brands, including Goodman, Rheem, York, and Daikin along with Carrier, Trane, Lennox, Bryant, and American Standard.

Pricing for HVAC Company in Napa, CA
| Service | Typical range in Napa |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a Napa job toward the top of those ranges is usually access and age. A condenser crammed behind a fence on a hillside lot takes longer than a clean pad behind a garage. A system that hasn’t been maintained in years often needs additional parts beyond the original failure. Whatever the job costs, the number is in writing before work begins, on every call, without exception.

FAQs About HVAC Company in Napa
Most Napa repair calls are scheduled the same day you call. We dispatch directly to Napa, and our technicians arrive inside the window we give you. Emergency and no-heat calls are treated as priority because a failed system in Napa’s summer heat is a health risk, not just a comfort issue.
Most Napa HVAC replacements and installations require a permit from the city, especially when equipment is relocated or ductwork is modified. Repairs and part swaps typically don’t. Dalton Heating & Air handles the permit paperwork on installation jobs so the work is done by the book and passes inspection.
We serve the entire city of Napa, from downtown to the surrounding hills and every neighborhood in between. Our dispatch is coordinated from the brand’s San Francisco Bay Area office, and crews serve Napa locally. If you’re in the Napa city limits, we’ll be there with a written price and a full-year guarantee.
