Denny's Heating and Air Conditioning

Call us for an estimate before you spend too much somewhere else!


Denny's Heating and Air Conditioning is a family-owned business that has been meeting the HVAC needs of the Napa Valley and north bay communities since 1993. With over 40 years of experience in the trade, we specialize in the installation, service, and repair of heating and air conditioning systems for all residential and commercial buildings. If you have a problem with your heater or air conditioner, we will determine if your current unit can be fixed before we recommend replacing the unit. Other HVAC contractors would rather simply sell you a new unit, because their technicians don't always have the experience to correctly diagnose your problem, and because they make more money when they sell you a whole new unit.

We also have a full sheet metal shop on site, and perform custom sheet metal fabrication for any application. We are licensed and bonded, with a C-20 HVAC license and C-43 sheet metal license. We carry full worker's compensation insurance for all of our employees, which limits your liability if our employees get injured on your property. We have an A+ rating with the Better Business Bureau, and we look forward to providing you with the best value for your money.
