Heating & cooling
AC & HVAC repair in San Mateo.
Heating and cooling across San Mateo, from downtown and Hillsdale homes to newer condo construction.
San Mateo covers the 94401, 94402, and 94403 ZIPs, a downtown and Hillsdale mix of older single-family homes and newer condos. A share of the older housing runs original forced-air furnaces with no central cooling, since the Bay's marine layer kept summers mild enough that AC was never standard, while remodels and newer condo construction brought in full ducted systems.
Furnace calls on the older side are the standard list: a thermocouple, an igniter, or a pressure switch reading a blocked condensate line. Where central air exists, the equipment is often old enough now for the usual capacitor and contactor failures, and we meter the actual part before quoting anything.
We run San Mateo with the Belmont and Foster City leg of our route, about 50 to 65 minutes from our San Ramon base. EPA Section 608 Universal certified, CSLB #1136642. The diagnostic is $99, credited toward the repair when you book it, with a written itemized quote before work begins.
Older furnaces in downtown and Hillsdale homes
A furnace that won't light or is throwing a fault usually needs a thermocouple, an igniter, or a pressure switch check, stocked parts and a same-visit fix in most cases. See furnace repair.
Newer condos and aging ducted systems
Remodels and newer condo construction brought in full ducted systems, and a share of that equipment is now old enough for capacitor and contactor failures. We meter the actual part before we quote anything. See AC repair.
No existing ducting, and the ductless option
Some of the older San Mateo homes have no ducts for cooling. A ductless mini-split adds it room by room without cutting chases into a house that wasn't built for them. We install Mitsubishi and Daikin, factory trained on both. Electricity here runs through Peninsula Clean Energy and gas through PG&E, and we confirm what's actually funding a rebate at the time we write your estimate. See ductless mini-split repair.
Common questions, San Mateo.
- Do you repair older furnaces in San Mateo's downtown and Hillsdale homes?
Yes. A thermocouple, igniter, or pressure switch covers most failures and most are same-visit fixes. We only recommend replacement when the heat exchanger is compromised.
- My condo's AC is aging. Is it worth repairing?
Usually yes, if it's a capacitor, contactor, or a fixable refrigerant leak. We meter the actual failed part and tell you honestly if the system's age changes that math.
- What does an HVAC service call cost in San Mateo?
The diagnostic is $99, credited toward the repair when you book it with us, with a written quote before work begins. We hold EPA Section 608 Universal certification and CSLB license #1136642.
