Heat Pump Installation & Service in South San Francisco
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 South San Francisco is the fog-line split between the old flatland neighborhoods and hillside Westborough.
Local climate and housing stock both shape a heat pump project here. South San Francisco sits under heavy fog for much of the year, especially in the older flatland neighborhoods below Sign Hill, while newer construction up in Westborough sits above the fog line and runs noticeably warmer. Neighborhoods like Winston Manor and Sunshine Gardens carry a lot of older housing built without ductwork, since nobody needed central air under that much fog. Westborough's newer hillside construction is a different story, built later and with more real cooling load to plan around.
In South San Francisco, 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 South San Francisco
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, fog-heavy air here still works its way into loose or aging connections over time, even without direct salt exposure. The fog-belt tract homes here were built with minimal or no ductwork, so a retrofit duct run is often undersized or improvised.
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.
