Common questions
Why is your range different from the quote I got?
Our range covers a like-for-like replacement with a standard unit. Code upgrades, moving the unit, new gas lines, dealer-only brands and same-day emergency service all push a real quote higher. Paste your quote into the quote checker to see which of those it includes.
Where do the numbers come from?
Equipment prices are online list prices we recorded in October 2026. Installation costs come from the Department of Energy’s analyses for its efficiency standards, inflated to August 2026 with the Consumer Price Index and adjusted to local plumber and HVAC wages from the Bureau of Labor Statistics.
Do you include permits?
DOE’s installation averages include typical permit costs spread across all jobs. Where we found a city’s published fee, the metro page shows it separately.
Why don’t you cover my city?
Every US ZIP code gets an estimate: metro wages for the 50 largest metros, statewide wages everywhere else. Metro pages exist for the 50 largest metros.
