Cost of furnace and ac installation — San Francisco, CA

Last updated: September 24, 2026

What affects the price

When you are looking at a new HVAC setup, the final number depends on a few moving parts. The physical size of your home and the necessary ductwork adjustments play a huge role. We also look at the efficiency ratings of the unit; higher efficiency models often cost more upfront but can change your monthly utility bills. Other factors include the type of fuel your home uses, specific brand preferences, and any modifications needed to your existing electrical system. It is best to look at these as investments in your comfort.
