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.
Plenty of Corte Madera houses were built without air conditioning. A heat pump adds cooling and replaces gas heating with one outdoor unit.
One heat pump handles cooling on warm days and heating in winter. MCE lists heat pump rebates; confirm eligibility with MCE.
Bayside lots have room but sit low and damp; hillside lots are tight. HAXX chooses a pad or wall bracket location that suits the site.
Ductless or slim-ducted systems cool bedrooms and living areas in houses that never had ductwork.

Yes. New or replacement cooling needs a Town building permit. HAXX files it and schedules the 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.
