AfterHVAC Company in Foster City, CA
Meadowsweet Heating & Air is the HVAC company Foster City homeowners call when bay air has done what bay air does: corroded a condenser coil, fouled an electrical contact, or pushed a 1980s furnace past its limits. We work on the equipment these houses actually have, from original gas furnaces to heat pumps retrofitted onto lagoon-facing properties. Every visit includes a written price before work begins, shoe covers and drop cloths inside the home, and a photo of the clean-up before our crew leaves. Call (747) 966-3037 for a free estimate, any hour.
Why Foster City Homes Are Different
Foster City was built almost entirely on dredged bay fill in the 1960s and 1970s, and its lagoon network means a large share of homes and condos sit effectively waterfront on San Francisco Bay. That location comes with a specific cost: salt-laden air off the lagoons corrodes condenser coils, electrical contacts, and refrigerant line fittings far faster than the same equipment would wear just a few miles inland. We routinely find coils on lagoon-adjacent streets in Foster City corroded through within 7 to 10 years, roughly half the lifespan the same part would see in San Mateo or Redwood City. When we install equipment here, we frequently apply marine-grade coil coatings as a standard step, something that would be considered unnecessary just a short drive east.
Most of the housing stock was built between the late 1960s and mid-1980s as part of one master-planned development. That means we see a lot of original ductwork, tight mechanical closets, and HOA-governed buildings with equipment-placement rules that affect any replacement project. Heating is the dominant need in Foster City. Central air conditioning was rarely included in original construction because the bay kept summers moderate, so today’s homeowners are often retrofitting AC into homes that were never designed for it. The persistent humidity from the bay and lagoons also accelerates duct condensation and increases mold risk around older air handlers, so we pay close attention to airflow and sealing on every job.
Our Main Foster City Services
Most Foster City homeowners call us for one of three reasons: an air conditioner that stopped cooling, a furnace that won’t fire on a cold bay night, or a system replacement that has to work around HOA rules and lagoon air. Each service has its own detailed Foster City page below.
AC Repair in Foster City
When a Foster City AC stops cooling during one of the brief but uncomfortable inland heat spells, the cause is usually the coastal environment. Salt corrosion on condenser coils and contactors is common on lagoon-front properties, and we test for it directly. Our technicians diagnose the fault, give you a written price before any repair begins, and carry replacement parts for Trane, Lennox, Goodman, and Rheem systems on the truck. We also check the condensate drain line, which clogs more often in Foster City because of the high ambient humidity and organic buildup from bay air. Read the full breakdown on our AC Repair in Foster City page.
Furnace Repair in Foster City
Most Foster City homes still run on the gas furnaces installed when the city was built, and those units are now 40 to 50 years old. When one fails in January, the house cools down fast because bay winds pull heat out of older single-pane windows. We repair flame sensors, gas valves, ignitors, and blower motors, and we always check the heat exchanger for cracks before any repair proceeds. A written quote comes before we touch anything, and our technicians wear shoe covers and lay drop cloths so the work stays off your floors. More detail is on our Furnace Repair in Foster City page.
AC Installation in Foster City
Installing air conditioning in a Foster City home usually means working around a few constraints at once: HOA equipment-placement rules, small mechanical closets, and salt air that shortens coil life. We quote a complete system replacement with written fixed pricing that includes the condenser, coil, line set, thermostat, and all permits. Because of the lagoon air, we discuss marine-grade coil coatings with every Foster City installation customer. We also handle the electrical and structural details so the finished job looks like it belongs on the house, not bolted on afterward. See the full process and pricing on our AC Installation in Foster City page.

What Foster City Customers Say
"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke
