New AC,
sized and installed right.
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.
AC or heat pump
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.
Ducts and airflow
Leaky or undersized ducts waste a new system. HAXX checks airflow before quoting.
Electrical check
Circuit, disconnect and panel capacity reviewed by HAXX electricians before install day.
Brands we install
American Standard and Mitsubishi Electric, among others, matched to the home and budget.
Permits and inspection
Mechanical and electrical permits pulled, city inspection scheduled.
FAIRFAX DETAILSAdding cooling
Adding cooling
in Fairfax.
Many older Fairfax houses were built with no air conditioning at all. A heat pump adds cooling and can take over from the furnace in winter.
01
One system, two jobs
A heat pump cools in summer and heats in winter, so adding cooling can also retire an aging gas furnace.
02
Homes without ducts
Cottages and cabins with wall heaters often have no ductwork. Ductless heads cool the hottest rooms without opening walls.
03
Tight and sloped lots
HAXX chooses an outdoor location with setbacks, drainage, line set routing and neighbors in mind before the permit.

GOOD TO KNOW
AC Installation in Fairfax: questions, answered.
Should I choose a heat pump or a straight AC in Fairfax?
A heat pump adds heating as well, and Bay Area Air District rules will limit sales of new gas furnaces from 2029. HAXX quotes both so you can compare.
Does a new AC need a Town permit?
Yes. HAXX applies for the mechanical and electrical permits with the Town of Fairfax and is present for inspection.
How long does an AC installation take?
Most replacements take one to two days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
Should I get a heat pump instead of an AC?
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.
