When your AC or furnace quits, you want it fixed once, not patched until next season. Napa HVAC finds the root cause and fixes it right, with fast, reliable service from the first call.
A broken AC or furnace doesn't wait, and neither should your service company. With technicians based around the Napa area, we provide fast, reliable service and hands-on care from experienced pros who know the climate and housing stock of our region.
Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. Every visit includes a safety check of the burners and venting, and you'll know the price before we start.
We take on the full range of comfort problems, from failed capacitors and cracked heat exchangers to ductless installs and commercial rooftop units, with the hands-on experience the job calls for.
Heat pumps sized for your climate, with backup heat set up correctly.
Complete heating and cooling systems designed around your home's actual load.

Call (707) 210-0201If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across Napa, and how we put a stop to each.
When the AC runs but the house won't cool, the fault is almost always one specific component. We find it and fix it fast.
AC repairA furnace that lights and then shuts down within seconds usually has a dirty flame sensor or a failing igniter, quick fixes for an experienced tech.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsWhen repair bills start stacking up, a modern high-efficiency system often costs less per month than keeping the old one alive.
System replacementIf some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
You'll get a clear written quote before any work starts, and the price you approve is the price you pay. That's why so many customers call us back.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
For over 12 years, Napa HVAC has been the trusted name for HVAC service in this part of CA. Our hometown technicians know the specific conditions that local comfort systems face, from the seasonal swings that work equipment hardest to coastal air that corrodes condenser coils.
Every technician on our team is seasoned, background-checked, and trained across every major brand and fuel type. We tailor every recommendation around the system you have and the way you use it. When the AC quits, you deserve a team that can be there fast, not a franchise dispatcher hundreds of miles away.
Talk to someone who actually knows heating and cooling. Honest, no-pressure pricing over the phone.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Pick up the phone and dial (707) 210-0201. A few quick questions later, your appointment is on the calendar, frequently the same day.
We inspect the whole system, not just the obvious symptom, and give you a straight answer: what failed, why, and what repair versus replacement really costs.
Most repairs finish the same visit, our trucks carry the common parts. Replacements are installed to code with proper sizing, sealed connections, and clean workmanship.
The job isn't done until conditioned air is flowing and verified. We'll also show you the simple habits, and offer the maintenance schedule, that add years to the system's life.

A house with no AC in a heat wave gets dangerous, not just uncomfortable. Here's what our team does from your first call to restore your comfort fast.
Our team answers your call promptly, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and gets you on the schedule, often same-day. We'll walk you through switching the system off if it's iced over or short-cycling in the meantime.
Often within hours, our fully equipped technician is on-site with the parts and tools required to diagnose and begin the repair in your home or business.
This is where the problem actually gets solved. We repair what's repairable immediately, and when replacement is the honest answer, we handle removal, disposal, and a code-compliant install without drama.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for systems in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Best decision we made on this house."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team had us cooling again before the dinner rush. They clearly understood what downtime costs a Napa business, and they came back the next week to fully service the second unit. They've got all our locations now."
"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."
We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.
We don't send a rookie with a gauge set and a hope. Each technician brings genuine field experience in diagnosis, safe gas and electrical work, and clean installation, the kind of depth that turns a service call into a lasting fix.
Effective doesn't have to mean oversold. We size systems honestly and install them to code with quality fittings and clean workmanship, so you get reliable comfort with minimal disruption to your household.
We don't wait for failures to profit from them. Every maintenance visit is thorough and documented. For hard-working systems, a $40 capacitor caught early can save a $2,000 compressor. That's the Napa HVAC way.
Wherever you are in our service area, we've got it covered, with fast repairs, quality installs, and maintenance plans reaching every community on our list.
