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.
Milpitas has online permit types for a same-location AC replacement and for a new AC with a new circuit. Larger scopes go to the Building Permit Center with a full application.
A heat pump cools like an AC and also heats. It qualifies for Milpitas and SVCE rebates when it replaces gas heating, which a standard AC does not.
Many older Milpitas homes have only a furnace. A ducted heat pump can use the existing ducts after an inspection of their condition.
HAXX selects the right online permit, such as ONL AC or ONL FURN REPL NEW AC, or files a full application when the job falls outside those scopes.
