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 East Palo Alto homes were built without central air. A heat pump adds cooling and can also take over heating from an aging gas furnace.
Homes without usable ductwork can take wall-mounted or ceiling mini-split heads instead of new ducts.
Where ducts exist, HAXX checks size, leakage and insulation before connecting a new ducted system.
HAXX submits the application to the City of East Palo Alto Building Division and is on site for the inspection.
