Heating & cooling
AC & HVAC repair in Half Moon Bay.
Heating repair and ductless cooling for the Coastside, where salt air and marine fog make central AC the exception.
Half Moon Bay anchors the Coastside, covering the 94019 ZIP code, and we also cover the smaller communities up the coast: Montara, Moss Beach, and El Granada. The marine layer here is thick enough, most of the year, that central air conditioning was never standard in the housing stock. Heating is mostly original wall furnaces or forced-air systems, repaired and maintained rather than replaced wholesale.
Salt air off the ocean speeds up corrosion on any outdoor equipment, coils, hinges, and exposed metal cabinet parts, so where a ducted system or a ductless outdoor unit does exist, it tends to show wear sooner than the same equipment would a few miles inland. We check for early corrosion on every Coastside service call.
We run the Coastside on a routed day out of San Ramon, about 65 to 80 minutes over Highway 92. 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.
Wall furnaces and forced-air systems: repair first
Most Coastside heating calls are a thermocouple, an igniter, or a pressure switch, stocked parts and a same-visit fix in most cases. We repair sound equipment rather than pushing a replacement on a furnace that still has service life left. See furnace repair.
Salt air and the equipment it shortens
Everything outdoors on the Coastside lives in marine air, and coils, hinges, and cabinet metal corrode faster than they would inland. We inspect for early rust and corrosion on every visit, and we're EPA 608 certified for any refrigerant work that comes with a corroded coil. See HVAC maintenance for the preventive side.
Adding cooling without existing ducts
Most Coastside homes were never built with ducts for cooling. A ductless mini-split adds it room by room, with the outdoor unit sited to minimize salt-air exposure where the property allows. We install Mitsubishi and Daikin, factory trained on both. See ductless mini-split repair.
Common questions, Half Moon Bay.
- Does salt air really affect HVAC equipment out here?
Yes, coils, hinges, and any exposed metal corrode faster than they would a few miles inland. We check for it specifically on every Coastside visit rather than treating the equipment like it's inland.
- Do you cover Montara, Moss Beach, and El Granada, not just Half Moon Bay itself?
Yes, those Coastside communities are part of our regular route.
- What does an HVAC service call cost on the Coastside?
The diagnostic is $99, credited toward the repair when you book it with us. We hold EPA Section 608 Universal certification and CSLB license #1136642.
