Equipment sized to the house, its windows and insulation, not to the old unit's label.
Adding cooling to a San Bruno 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 Mills Park, Rollingwood, Crestmoor, Portola Highlands, Huntington Park and Lomita Park and the rest of San Bruno. 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.
Many San Bruno homes were built after World War II without air conditioning. A heat pump adds cooling and replaces or backs up the furnace in one system.
Cooling demand is low in San Bruno. A heat pump earns its cost all year by also handling heating.
Homes with a forced-air furnace can often reuse the ducts after HAXX checks sizing and leakage.
Ductless heads suit bedrooms, additions and homes with no attic space for ductwork.
