Equipment sized to the house, its windows and insulation, not to the old unit's label.

Serving the Old Quad, Maywood Park, Fairmede, Pomeroy Green, Agnew and Rivermark and the rest of Santa Clara. Share your address to confirm availability.

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.
Santa Clara doesn't require a heat pump when you replace an AC in an existing home. Many owners choose one anyway, because a heat pump cools and also replaces the gas furnace.
HAXX prices both options. A heat pump costs a little more than a cooling-only AC and can retire the gas furnace too.
Many Old Quad and mid-century homes never had ducts for cooling. A mini-split or slim-ducted system adds cooling without major demolition.
For a single-family home, duplex or ADU, an HVAC change-out can often use the city's Simple Building Permit. Condos, townhomes and historic properties need a regular permit.

In an existing home, yes. Santa Clara's all-electric rule applies to new buildings and to alterations that change more than 50% of the building.
Most replacements take one to two days. The city inspection is scheduled after that.
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.
