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 Helena
Given Montana’s cold northern continental climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Helena homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.
