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.
Pittsburg's climate leans hot and dry in summer. Many owners replacing an AC choose a heat pump, which cools the same way and can also take over heating.
A heat pump costs little more to install than a cooling-only unit in many homes and removes the need for a separate gas furnace later.
Leaky or undersized ducts in older Old Town and Oak Hills homes can undercut a new system. HAXX inspects them as part of the estimate.
HAXX pulls the City of Pittsburg permit and schedules the inspection through the Accela Citizen Portal.

Often it makes sense, since a heat pump provides cooling plus heating. HAXX will compare both options for your house.
Replacing an AC or heat pump requires a City of Pittsburg permit. HAXX handles the application and inspection.
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.
