Heat Pump Installation & Service in Foster City
A heat pump project is a sizing and ductwork question as much as an equipment question. We run a Manual J load calculation rather than defaulting to a round number, and we tell you honestly when the existing ducts support a ducted conversion versus when a ductless mini-split per room is the cleaner path. The detail that matters in Foster City is the fill soil settling under the ductwork and the damp lagoon-front air.
Local climate and housing stock both shape a heat pump project here. Foster City is built almost entirely on filled marshland reclaimed from the bay starting in the 1960s, laced with the lagoons the city is known for, and the lagoon-adjacent air runs damp even on a mild day. The housing is unusually uniform for the Peninsula: 1960s and 70s tract construction on engineered fill, much of it lagoon-front or a short walk from the water. Sixty years of settling in that fill soil has shifted more than a few slabs, which shows up as duct runs that no longer sit level and condensate lines that no longer drain the way they were installed.
In Foster City, we run the load calculation, lay out ducted versus ductless, and check current BayREN, PG&E, and manufacturer rebates before you commit to anything. New installs carry a 10-year manufacturer parts warranty, with labor at 2 years standard and the full 10 years while the equipment stays on our maintenance plan.
What we run into in Foster City
Right-sizing with a real load calculation. We run Manual J against the home's actual design temperatures instead of rounding up, which usually means smaller, more efficient equipment than homeowners expect.
Ducted conversion versus ductless mini-split. Where the existing ducts have been maintained, a ducted heat pump conversion usually works. Where ducts are gone or impractical, a ductless mini-split per primary room is the cleaner path, with no plaster damage and full climate control.
Equipment and placement built around local conditions. The damp, bay-adjacent air here is harder on exposed electrical connections than a drier inland spot would be. Sixty years of settling on filled bay soil here has left more than a few duct runs out of level or pinched at a joint.
Rebate paperwork handled. We check BayREN, PG&E, and manufacturer instant rebates against your equipment and address and handle the submission, confirming what is currently paying at the estimate.
Pre-2029 conversion planning. With BAAQMD Rule 9-4 restricting new gas furnace sales starting in 2029, we help you plan the conversion on your timeline instead of being forced into it later.
