JVG in Calistoga

HVAC service in Calistoga, done the family way.

One Napa-based family team · 25 years of experience · Lic. #1103018 (C-20 HVAC · C-10 Electrical · B General)

Calistoga sits at the hot end of Napa Valley — summer afternoons here routinely run several degrees above Napa proper, and A/C systems that coast elsewhere get worked to their limits. If your system struggled last July, it isn't going to age out of the problem; a $69.99 inspection tells you exactly where it stands before the next heat wave.

The town's older cottages and resort-era homes often mix vintage construction with decades of piecemeal HVAC work. We're comfortable in old houses: we inspect what's actually there, explain it in plain language, and never sell repairs at the door.

Heat pumps deserve a special mention in Calistoga: one system that handles brutal summers and mild winters, ready for California's 2027 rules — and we've installed them across the valley.

FAQ

Common questions,
honest answers.

What areas does JVG service?

Napa Valley and Sonoma County — including Napa, Sonoma, St. Helena, Yountville, Calistoga, Petaluma, Healdsburg, Sebastopol, Vacaville, Fairfield, Glen Ellen, Kenwood, and Windsor.

What is the $69.99 preventative maintenance inspection?

A visual and operational inspection from a JVG technician — no repairs, cleaning, or component replacements are included in this visit. We inspect the blower motor and fan, test the ignition system and pilot, verify safety controls and limit switches, inspect accessible gas piping for leaks or corrosion, inspect the venting system, check carbon monoxide levels with test instruments, examine the heat exchanger for visible cracks or damage, inspect the condenser coil, tighten accessible electrical connections, check thermostat operation, and test the full furnace cycle. You get a written assessment in plain language — no pressure, no upselling. Any repairs are quoted separately for your approval.

What are the new regulations for gas furnaces and water heaters in California?

California is moving away from gas-burning home appliances. Under the state's zero-emission appliance standards, new residential gas furnaces and gas water heaters are being phased out beginning in 2027, with electric heat pump models becoming the standard. Heat pump HVAC systems and heat pump water heaters meet the new rules — we install both and can help you plan the switch before the deadline so you're never caught off guard.

Are you licensed and insured?

Yes. Contractors License No. 1103018 with C-20 HVAC, C-10 Electrical, and B General Contractor classifications. Fully bonded and insured for residential work across California.

How much does a new HVAC system cost?

Most residential installations range from $6,000 to $15,000 depending on home size and system type. We start every install with a free in-home estimate — call (707) 531-9216 for a quote.

Do you offer same-day service?

Yes — same-day service is available for emergencies. Call or text (707) 531-9216 and we'll move you to the front of the line.

Do you handle electrical work?

Yes. Our C-10 Electrical license covers panel upgrades, new circuits, lighting, and general residential electrical repairs — so you don't have to call a separate electrician for HVAC projects.

Ready when you are.
