Equipment sized to the house, its windows and insulation, not to the old unit's label.

Serving Fuller Park, Napa Abajo, Alta Heights, Browns Valley, Westwood and Shurtleff and the rest of Napa. Share your address to confirm availability.

Central air conditioners and heat pumps that also cool. Every installation starts with sizing and a look at your ducts and electrical panel, not with a model number.
Equipment sized to the house, its windows and insulation, not to the old unit's label.
Compare a straight AC with a heat pump that also heats. In many homes the heat pump costs little more and replaces the furnace later.
Leaky or undersized ducts waste a new system. HAXX checks airflow before quoting.
Circuit, disconnect and panel capacity reviewed by HAXX electricians before install day.
American Standard and Mitsubishi Electric, among others, matched to the home and budget.
Mechanical and electrical permits pulled, city inspection scheduled.
Many older Napa homes were built without central air. A heat pump adds cooling and replaces gas heating with one system, which is where MCE rebates apply.
A heat pump cools the same way an air conditioner does and also heats, so an aging furnace can retire at the same time.
Period homes near downtown often lack ductwork. Ductless or slim-ducted heads avoid tearing into plaster walls.
HAXX submits the City of Napa building permit and schedules the final inspection.

For most homes a heat pump makes sense, since it covers both cooling and heating and qualifies for MCE rebates when it replaces gas heat. HAXX will price both if you ask.
Most replacements take one to two days. New duct runs or multi-zone ductless systems can take longer.
Most replacements take one to two days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
A heat pump cools exactly like an AC and also heats. If your furnace is aging, it is worth comparing both on the same estimate.
