AC Installation Field Guide for Foster City

Old unit never cooled evenly

That is often a duct, return, insulation, or sizing issue. A new condenser alone may repeat the same comfort problem.

Home addition or remodel

Added rooms change load and airflow. The existing system and duct layout should be checked before equipment is selected.

No ductwork or poor duct access

Ductless mini-splits or heat pumps may be stronger options for rooms, garages, additions, and homes with limited attic space.

Electrical or thermostat limitations

Panel capacity, disconnects, thermostat wiring, and heat pump compatibility can affect the real installation scope.

How We Decide the Next Step

Load calculation before equipment choice

Oversized AC can short cycle; undersized AC can run constantly. The right size comes from the home, not just the old nameplate.

Ducts decide comfort

Duct leakage, undersized returns, and poor room airflow can waste a good installation.

Heat pump should be discussed

On the Peninsula, a heat pump can solve cooling and heating in one system when ducts, electrical capacity, and comfort goals fit.
