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.
HILLSBOROUGH DETAILSNew cooling for
New cooling for
Hillsborough homes.
Many older Hillsborough houses were built without central air. A heat pump adds cooling and replaces gas heat at the same time, which is what WestLight Energy (formerly Peninsula Clean Energy) rebates reward.
01
Heat pump instead of AC-only
A heat pump cools like an AC and also heats, so one system can retire a gas furnace. HAXX prices both options.
02
Historic and custom homes
Plaster walls, finished attics and architect-designed rooms call for careful duct or ductless routing. HAXX plans the route before quoting.
03
Outdoor unit placement
On hillside lots, HAXX places condensers for service access, setbacks and sound, away from bedrooms and neighbors.

GOOD TO KNOW
AC Installation in Hillsborough: questions, answered.
Do I need a permit to install AC in Hillsborough?
Yes. The Town lists HVAC systems among work that needs a permit. HAXX applies through eTrakit and meets the inspector.
Can I still install a standard AC in Hillsborough?
For an existing home, yes. HAXX usually suggests a heat pump because it adds heating as well as cooling.
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.
