Heat Pump Installation & Service in South San Francisco

A heat pump project in South San Francisco is a sizing and duct question as much as an equipment question, and we plan around the heavy fog and the ductless-friendly older housing below Sign Hill.

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.


Heat Pump Installation & Service in South San Francisco: common questions

Do you handle heat pump installs and service out in South San Francisco?

Yes. We're based in San Ramon and cover the Peninsula including South San Francisco, San Bruno, and Daly City. We dispatch the closest available tech and give you a realistic arrival window when you call, rather than a blanket promise we can't back up. Call (925) 999-4095.

Our house is in the older flats below Sign Hill and honestly the fog means we barely use the system. Is this still worth a service call?

Usually yes, especially since a lot of the complaint on homes like yours turns out to be about heating or airflow rather than cooling, which fits with how little real cooling load this fog belt actually has. If your home never had ductwork installed originally, that retrofit is often where the actual issue lives rather than the equipment.

What rebates can I actually use for a heat pump right now?

BayREN, PG&E, and manufacturer instant rebate programs are the ones currently paying for addresses in this area. We confirm exactly what applies to your equipment and address at the estimate, and we don't quote anything that has already closed.
