2026 installed-cost ranges in San Jose
Ranges below are typical installed prices for South Bay homes before any rebates or tax credits. Final price depends on the site work below.
Gas tank (40–50 gal)
$2,200 – $3,800
Like-for-like swap. Pricing varies with venting, expansion tank, strapping, gas/water shutoff condition, and permit fees.
Gas tankless (whole-home)
$4,800 – $8,500
Often needs upsized gas line, new stainless venting, condensate drain, and recirculation planning.
Heat-pump water heater (50–80 gal)
$5,500 – $9,500 before rebates
Needs a 240V circuit, condensate drain, and sufficient airflow. Heaviest rebate stack — net cost often $3k–$6k after incentives.
Commercial / multifamily
Quoted on site
Sizing, recirculation, code, and downtime planning drive cost. Send photos for a phone-first scope.
What moves your price up or down
Equipment tier
Standard tank, high-efficiency tankless, and heat-pump units sit at very different price points.
Electrical work
Heat-pump installs usually need a new 240V circuit. Older panels may need a sub-panel or upgrade.
Venting & gas line
Tankless often needs new stainless venting and upsized gas. Tank-to-tankless conversions add cost.
Code & permits
San Jose installs include seismic strapping, drain pan, expansion tank, T&P discharge, and permit/inspection fees.
Location & access
Attic, closet, exterior, or tight garages affect labor time, lift equipment, and disposal.
Rebate stacking
TECH + federal + local CCA rebates can change the net cost on a heat-pump install dramatically.
