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.
Plenty of Pleasant Hill houses built in the 1950s never had central air, and many original units have been replaced at least once. A heat pump now covers cooling and heating in one system.
A heat pump costs little more than a matching AC and removes the need for a separate furnace, which Air District rules restrict for new sales from 2029.
For houses with no ductwork or a converted garage, ductless or slim-ducted units add cooling room by room.
HAXX files the city permit, installs to the manufacturer's specs and meets the Pleasant Hill inspector.

For most homes a heat pump, since it cools the same way and can retire the gas furnace. MCE rebates may apply to heat pump systems; confirm terms first.
A typical changeout is done in a day or two, then the city inspects. New ductwork adds time.
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.
