HVAC System Installation in San Francisco, CA

A straightforward furnace or AC replacement on existing ductwork usually takes one day. A full system with new ductwork, or a multi‑zone ductless installation, typically takes two to three days. Your quote lists the expected schedule before work begins.

Yes. San Francisco and most Bay Area cities require a mechanical permit to install or replace heating and cooling equipment, along with California Title 24 energy code inspections. Our team pulls and manages the permit as part of every installation.

For most Bay Area homes, a heat pump is the stronger choice because mild winters keep it in its efficient operating range and one system both heats and cools. A gas furnace can still suit a home that already has gas and does not need cooling. We compare both options during your estimate.

Yes. Ductless mini‑splits are one of our most common installations in older San Francisco homes. Single‑zone and multi‑zone systems need only small wall openings, give each room its own control and avoid the cost of adding ductwork.

CleanPowerSF customers may qualify for up to $1,200 on a qualifying heat pump, plus $600 more for CARE or FERA customers. Peninsula and East Bay cities have their own utility programs. Rebate terms change often, so we confirm what your address qualifies for before quoting.

Our installations include up to a 12‑year installation warranty in addition to the manufacturer's equipment warranty. Every job ends with a written warranty summary so you know exactly what is covered.

Yes. Financing through Wisetack is offered on every estimate, subject to approval, with no origination fees and no prepayment penalties. Many homeowners combine financing with rebates and our current $500 off HVAC installation offer.
