San Francisco HVAC FAQ
Do I need AC in San Francisco?
Most days, no. But a heat pump replaces an old furnace and adds cooling for the occasional heat wave, which is why it's the most common upgrade.
Where can the outdoor unit go on a San Francisco row house?
Common spots are the rear yard, a side setback, a roof or a garage wall. Placement must meet city noise and setback rules.
