Load calculation
Equipment sized to the house, its windows and insulation, not to the old unit's label.
Adding or replacing cooling in Cotati? HAXX installs heat pumps and central AC sized to the house, with the City of Cotati permit included.
Serving the downtown Plaza around La Plaza Park, Old Redwood Highway, the Gravenstein Highway corridor, Stony Point Road and the area near Kotate Park and the rest of Cotati. 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 Cotati homes were built without central air because fog through the Petaluma Gap keeps summers cool. Hotter spells are when owners start asking about cooling.
A heat pump cools on warm days and replaces gas heating the rest of the year, with one outdoor unit.
Ductless heads can cool a bedroom or office without opening walls or adding attic ductwork.
The City's electrification guide asks for a sound calculation at the nearest property line on gas-to-heat-pump conversions. HAXX plans outdoor unit placement with that in mind.

Given Cotati's long heating season, a heat pump usually makes more sense because it also replaces gas heating. HAXX will compare both for your home.
Most replacements take one to two days, followed by the City inspection.
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.
