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 Lafayette homes date from the 1950s and 1960s, when the population nearly tripled, and some were built without central air. Inland summer heat makes cooling a common upgrade.
A heat pump cools like an AC and also heats, so one outdoor unit can replace both the AC and the gas furnace.
Where adding ducts is impractical, ductless or slim-ducted units cool bedrooms and living areas.
AC and HVAC replacements at single-family homes go directly to Contra Costa County for the building permit, with no City zoning review.
