Equipment sized to the house, its windows and insulation, not to the old unit's label.
Adding cooling to a Sebastopol home that never had it? HAXX installs heat pumps that cool in summer and heat in winter, with the panel and permit handled.
Serving downtown and Main Street, The Barlow district, Park Village, the Bodega Avenue corridor, the Laguna de Santa Rosa edge and homes near Ragle Ranch Regional Park and the rest of Sebastopol. 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.

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 Sebastopol homes were built without air conditioning. A heat pump adds cooling and replaces gas or electric resistance heat with one system.
Sonoma Clean Power rebates apply to qualifying heat pumps, not cooling-only equipment. That tips most projects toward a heat pump.
Homes with crawl space or attic ducts can take a ducted unit. Cottages and ADUs often suit wall-mounted heads.
HAXX files the mechanical and electrical permit through Sebastopol's e-permitting portal and attends the inspection.

The work was completed carefully, and our air conditioner is now working well.”

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.
