- System short-cycling
- High energy bills without explanation
- No heat or uneven heat between rooms
San Mateo homes, up close
The San Mateo-Hayward Bridge starts on the city's east side. Caltrain stops at three stations in the city.
Sugarloaf Mountain open space is on the west side. Homes here may have anything from a decades-old furnace to a new ductless heat pump added during a renovation. Tell the tech exactly what you have. Parts of the east side are low-lying near the Bay.
Many older homes near the Bay were built without central air, and ductless mini-splits are a popular way to add cooling. Laurelwood has hillside ranch homes from the 1950s and 1960s.
Utilities, permits and licensing
Ask about utility rebates before you replace equipment. PG&E and other local programs have offered incentives for efficient systems and heat pumps at various times. In California, licenses for heating and air conditioning contractors come from the Contractors State License Board.
Central Park downtown has a Japanese tea garden. Your water bill comes from Cal Water, sewage is handled by the wastewater plant the city runs with Foster City, and the City of San Mateo Building Division issues building permits. Hillsdale Shopping Center has been a regional mall since 1954.

Quick answers
Why is water pooling near my furnace or AC?
Usually a clogged condensate drain or a failed condensate pump. Turn the system off and have it looked at to avoid water damage.
What is a heat pump?
It moves heat instead of making it, heating in winter and cooling in summer. Modern cold-climate models work well even in freezing weather.
Is there anything local about HVAC service in San Mateo?
Shoreview is in the flats near the Bay. Many older homes have raised foundations and crawl spaces. Baywood and San Mateo Park have many 1920s and 1930s homes. Those details help the heating and cooling company plan the visit.

We're a referral line, not a repair company. An outside heating and cooling company quotes the job, does the work and stands behind it. It's fine to say no if the quote doesn't sit right. The pro gives you a price before any work starts, and it's your call whether to go ahead.
