What HVAC Installation Covers
Whether you're replacing a system that's on its last legs or fitting out new construction, a correctly sized, correctly installed HVAC system is the difference between a house that's comfortable for 15+ years and one that's fighting you every summer and winter. Next HVAC handles the full scope: load calculations, ductwork evaluation, equipment selection, permitting, and a clean installation day.
We install and service furnaces, central AC, heat pumps, and ductless mini‑split systems from major manufacturers, including Mitsubishi Electric. Every installation includes a walkthrough of the equipment, a written warranty summary, and a follow‑up check before we consider the job closed.

Frequently Asked Questions
Most residential installs run from $4,700 for a furnace swap to $10,500+ for a full heat pump system, depending on equipment tier, ductwork condition, and access. We provide a firm, written quote after an in‑home visit — see our Prices page for a full breakdown by system type.
A straightforward furnace or AC replacement is usually done in a single day. Full systems with new ductwork, or ductless multi‑zone installs, typically take 2–3 days depending on scope.
Yes, most jurisdictions in the Bay Area require a mechanical permit for HVAC installation or replacement. We pull and manage permits as part of the installation so you're not left dealing with the city yourself.
The right size comes from a Manual J load calculation, not square footage alone — insulation, window count, ceiling height and local climate all factor in. We run this calculation before quoting equipment so you don't end up with a system that short‑cycles or can't keep up.
