To put it in terms any self-respecting Upper Midwesterner should understand: Suddenly losing water heater function mid-shower is about as pleasant as purifying yourself in the waters of Lake Minnetonka in the winter — or, for that matter, any other body of water in the characteristically cold Land of 10,000 Lakes.

Your water heater powers your dishwasher, clothes washer and the hot shower you crave at the end of the day. When it goes kaput, it's not so much a matter of whether you should have it serviced, but how much that service will cost. And if your hot water is already out, the last thing you want right now is to be blindsided by exorbitant water heater service fees. If you’re calling around for estimates, these figures should give you a ballpark idea of how much you can expect to pay, from the Canadian border to the Twin Cities.
Repair and replacement costs vary depending on where you live. For comparison, the national average for diagnosis is $101, for repair is $359 and for replacement is $1,396. The good news? We're seeing prices that are, on the national level, lower than when we first reported this data in 2021. National average diagnosis fees are up just $2 in four years, while average repair and replacement costs are down 27% and 20% respectively.
The following average prices are based on aggregated HomeServe data reported by our network of contractors across the state of Minnesota:
Water Heater Diagnosis: $111
The technician will charge you a fee to come out to your home, tell you what’s wrong with your system and determine whether it needs to be repaired or replaced. For Minnesotans at large‚ this fee is 10% higher than the national average.
Water Heater Repair: $396
Any number of things may be going wrong with your water heater — issues with the gas control valve, a faulty thermostat or a combination of several malfunctions. This estimated repair price includes replacement parts and the labor to install them. Water heater repairs cost the average Minnesota resident about 10% more than the national average.
Water Heater Replace: $1,732
Water heaters don’t last forever, and a breakdown might be a sign that yours is on its way out. At the end of your water heater’s usable life (about 10 years), you'll need to spring for a new one. Minnesota’s average replacement price is 24% higher than that of the nation.
(Note that HomeServe water heater data should generally be assumed to refer to conventional “tanked” models — the most common type — as opposed to tankless or “on-demand” models, which can cost roughly twice as much.)
