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

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 Cupertino homes, from Rancho Rinconada rebuilds to Lynbrook ranches, never had central air or have one aging unit for two floors. A new system starts with a load calculation.
A heat pump cools like an AC and also heats, so it can replace a separate furnace. SVCE's advisor can help find incentives for the switch.
Eichlers and remodeled homes without attic space usually get ductless heads in the rooms that overheat.
Cupertino's instant furnace permit excludes systems with AC, so cooling installs go through a standard permit. HAXX handles it.

A heat pump does both jobs, so most owners replacing a furnace and AC choose one. HAXX quotes either option.
Yes. HAXX installs Mitsubishi Electric ductless and ducted systems and American Standard ducted equipment.
Most replacements take one to two days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
