Load calculation
Equipment sized to the house, its windows and insulation, not to the old unit's label.
Adding air conditioning to a Piedmont home, or replacing an old unit? HAXX recommends a heat pump that cools in summer and heats in winter.
Serving Lower Piedmont, Upper Piedmont, Baja Piedmont, the Sea View Avenue area and Estates Drive and the rest of Piedmont. 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.
Plenty of Piedmont homes were built without air conditioning. A heat pump adds cooling and can retire a gas furnace at the same time.
A heat pump costs little more than a cooling-only unit and handles heating too, which matters if the furnace is aging.
Piedmont's electrical amendments require future induction, dryer and EV circuits to be counted when AC or electric heat is added to an existing home.
Lots on hillside streets are often tight. HAXX picks a location that respects setbacks and neighbors.

For most homes a heat pump makes more sense: it cools, heats and can replace the furnace. HAXX prices both if you want to compare.
Not always. HAXX runs the load calculation Piedmont requires before quoting, so you know in advance.
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.
