Air Conditioning in San Mateo: what's different
Air Conditioning work in San Mateo follows the local climate. Mixed climates get real summers and real winters, so the AC has a full season of work and then sits idle. Spring start-up problems such as weak capacitors, low charge and clogged drains are common.
A common San Mateo pattern: homes without AC. Heat waves drive interest in cooling.
The air conditioning services San Mateo homeowners ask for most are AC Replacement & Installation. Correctly sized new systems, SEER2 ratings and refrigerant changes.
The City of San Mateo Building Division issues mechanical permits, and California requires C-20 licensed contractors.
