What affects the price

The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.
