HVAC Installation & Replacement FAQ for San Francisco Homeowners

How often should San Francisco homeowners get hvac installation & replacement?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from hvac installation & replacement at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need hvac installation & replacement?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How long does HVAC installation take?
A standard split system replacement (air handler + condenser) typically takes one day. New construction installs or major ductwork projects take longer.
How do I know what size system I need?
System size should be based on a Manual J heat load calculation accounting for square footage, insulation, windows, ceiling height, and climate. Oversized systems short-cycle, causing comfort and humidity problems.
What SEER rating should I choose?
Minimum efficiency today is 14–16 SEER depending on your region. Higher SEER (18–25) costs more upfront but reduces operating costs. Calculate payback based on your local energy rates.
Are there rebates for new HVAC systems?
Yes. The Inflation Reduction Act provides federal tax credits for high-efficiency equipment. Many utilities offer additional rebates. We identify all applicable incentives when quoting.
