Generic cost pages skip the things that actually decide your price and your unit’s lifespan here — local code, water, and the money you can claim back.
Recommended unit for Flagstaff
Given Arizona’s hot desert climate and electric water heating, heat-pump (hybrid) is the sensible default for most Flagstaff homes. Warm incoming water means a tankless delivers its full flow with no cold-inlet penalty. A pro can confirm the right size and fuel for your home.
