New AC,
sized and installed right.
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.
AC or heat pump
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.
Ducts and airflow
Leaky or undersized ducts waste a new system. HAXX checks airflow before quoting.
Electrical check
Circuit, disconnect and panel capacity reviewed by HAXX electricians before install day.
Brands we install
American Standard and Mitsubishi Electric, among others, matched to the home and budget.
Permits and inspection
Mechanical and electrical permits pulled, city inspection scheduled.
MILL VALLEY DETAILSNew cooling for
New cooling for
Mill Valley homes.
Many older Mill Valley homes were built without air conditioning. Adding it now usually means a heat pump, which covers heating too.
01
Heat pump over AC-only
One outdoor unit handles cooling and heating, so a gas furnace can stay as backup or be retired later.
02
Quiet placement
The city reviews a sound calculation at property lines. HAXX picks quiet equipment and a compliant location.
03
Homes without ducts
Cabins and cottages without ductwork often suit ductless or slim-ducted systems.

GOOD TO KNOW
AC Installation in Mill Valley: questions, answered.
Do I need a permit to add AC in Mill Valley?
Yes. A/C and heat pump installs need a mechanical permit with a site plan, specs and noise calculations. HAXX applies through eTRAKiT.
Can I add AC to a house with no ducts?
Yes. Ductless mini-splits or slim-ducted units work well in homes without ductwork.
How long does an AC installation take?
Most replacements take one to two days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
Should I get a heat pump instead of an AC?
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.
