Chris was very friendly and helpful. Would definitely hire again.
The service technician is very professional. He explains what he is doing and looking for when servicing the boiler.
Fast, friendly and affordable service!! Didn’t expect to have someone available to swing out to help with my AC on the hottest day of the year, but they had a service tech at my house in less than two hours. So impressed with everyone who helped me today. Thank you guys so much!!!

Answers from the Tower Ave shop
Right here: 1808 Tower Ave in Superior. This is our home base, where the trucks park and the schedule gets run. When you call (715) 817-4404, a real person answers.
Yes. According to the U.S. Census Bureau’s American Community Survey 2024 5-year estimates, about 36 percent of Superior’s homes were built before 1940, and the median year built is 1957. Original radiators, aging forced-air and galvanized supply lines are regular work. Since Botten Plumbing joined us in 2021 we handle the heating and the plumbing side of all of it.
No, and doing it all at once is not always the right call. Galvanized corrodes from the inside, so the worst runs are usually the horizontal ones and whatever sits closest to the meter. Replacing those first buys back most of the pressure for a fraction of the cost. We will show you what we found and let you stage the rest.
Worth finding out before anyone digs. Seasonal backups usually mean roots or a bellied section in the lateral between the house and the main, which is the homeowner’s responsibility. A camera inspection shows whether jetting will hold or whether the line needs work.
By calculating it, not by matching the sticker on the old one. Square footage, insulation, window area and air sealing all move the number, and a lot of older Twin Ports homes have been insulated since their original furnace went in. Oversizing is the common mistake: it short-cycles, wears parts faster and leaves the house less comfortable, not more.
Eight to twelve years for a standard tank, and hard water shortens that. The tell is usually rusty water, a rumbling tank as sediment cooks on the bottom element, or moisture at the base. A tank that is weeping is close to failing, and that is the time to plan a replacement.

Yes, licensed, bonded, and insured in Wisconsin, with Minnesota licensing for the Duluth side of the bridge as well.
Long. NOAA’s 1991-2020 normals for the Superior weather station average about 8,822 heating degree days a year (a measure of how much heating a place needs), a January low around 6°F, and about 28 nights a year below zero. A heating system here works hard, so a yearly checkup is worth it.
