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 Larkspur homes were built without AC. A heat pump adds cooling and can replace an old gas furnace in the same project.
Larkspur asks for a site plan with new or replacement AC. HAXX draws the outdoor unit location and submits it in eTRAKiT.
A heat pump costs little more than a matching AC and covers heating too. MCE lists rebates for heat pump systems; straight AC usually has none.
Near Larkspur Marina and Riviera Circle, where the city notes king tide flooding, HAXX plans equipment pads with water in mind.
