Installation costs typically range from $2,500 to $4,500 depending on your home’s existing setup and the unit size needed. Homes requiring gas line upgrades or electrical service modifications cost more than straightforward replacements.
The biggest cost variables are whether you need new gas lines (common in older North Sacramento homes), electrical upgrades for electric units, or extensive venting modifications. We provide detailed estimates that break down equipment, labor, and any necessary upgrades.
