Load calculation
Equipment sized to the house, its windows and insulation, not to the old unit's label.
Adding cooling to a San Francisco home that never had it? HAXX installs heat pumps and ductless systems that cool on hot days and heat the rest of the year.
Serving the Sunset, the Richmond, Noe Valley, Bernal Heights, Pacific Heights and West Portal and the rest of San Francisco. 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.
Most San Francisco houses were built without air conditioning. Late-summer and fall heat waves have made cooling a common request in the Mission, Noe Valley and Bernal Heights.
A heat pump costs little more than a cooling-only system and also replaces gas heating, which can qualify for CleanPowerSF bill credits.
Many older homes have wall heaters or floor furnaces and no ducts. Wall-mounted or ceiling-cassette mini-splits avoid opening walls.
Outdoor unit locations, roof penetrations and noise limits are often set by the HOA. HAXX helps you plan placement before you apply for approval.
