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 Belvedere homes were built without central air. A heat pump adds cooling and replaces gas heating in one system.
It costs about the same to install as a new AC and furnace pair in many homes, and gives efficient heat for foggy months as well as cooling.
HAXX selects inverter units with low sound ratings and places them away from bedrooms and neighboring decks where the lot allows.
HAXX applies to the City of Belvedere Planning and Building Department for the mechanical and electrical permits and meets the inspector.

For most homes a heat pump, because it cools on warm days and heats through the damp, foggy season. HAXX compares both during the estimate.
Yes. Mechanical and electrical permits come from the City of Belvedere Planning and Building Department. HAXX prepares and files them.
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.
