What HVAC systems does this calculator estimate?

It covers common San Diego replacements — a furnace, air conditioner, heat pump, or a full-system swap — so you can get a rough planning number before calling contractors.

Does the estimate include installation and removing the old system?

Yes. The range is a planning-grade estimate reflecting typical equipment plus installation for the system you choose. Permits, ductwork changes, and removal can shift the final bid.

How accurate is this HVAC estimate?

It's a rough range — usually within about 15–25% of a real bid. A licensed contractor will confirm the exact cost after a load calculation and site assessment.
