AC installation in San Mateo: what we fix

A correct AC installation starts with Manual J sizing, matched indoor and outdoor equipment, a new line set or flushed lines, a properly sized breaker and disconnect, a level pad, correct refrigerant charge by superheat and subcooling, and a commissioning test of airflow and temperature split. Skipping any of those steps is why so many new systems underperform. We do not skip them.

Replaced our 20-year-old furnace and AC with a heat pump. Clean install, explained everything, and our summer bill dropped noticeably. Great AC installation experience.

AC Installation & Replacement in San Mateo: frequently asked questions

How long does an AC installation take?

For California summers a 16 SEER2 or higher unit usually pays back the extra cost through lower bills. We will show you the operating cost of each option.

Do you remove and dispose of the old unit?

Yes. Removal, refrigerant recovery and disposal of the old equipment are included in every installation.
