What Affects the Final Price

Installation complexity: A simple swap in a garage is cheapest. Closet installs, attic installs, or units requiring new venting or gas line upgrades cost more.

Fuel-type switch: Converting from electric to gas (or vice versa) requires additional work — expect to add $300–$800.

Code upgrades: Older homes may need seismic strapping, an expansion tank, updated permits, or a drip pan — these are typically $100–$300 extra.

Brand and efficiency rating: Standard efficiency units are significantly cheaper upfront than high-efficiency or hybrid heat-pump models, but high-efficiency units save money monthly.

Best Time to Replace

Don't wait for a full failure. A leaking or failed tank can cause thousands in water damage. If your unit is 10+ years old and having issues, get quotes now. Most plumbers can install a replacement within 1–2 business days.
