Boiler Repair & Service in Prescott, WI
Boiler repair in Prescott's 1800s riverfront houses starts with a $79 trip charge, waived when you say yes to the repair. A visit starts with system pressure and the circulator, then the chimney and any radiators that stay cold.
Boiler service calls in Prescott homes
The 1800s and early-1900s houses on the terraces above the St. Croix and Mississippi confluence are where Prescott's boilers are found. Some still run on the original radiators and piping, and others carry big round ducts from gravity furnaces converted to forced air. Those houses have high ceilings, fieldstone or brick basements and original windows, so a boiler runs long cycles through January.
If a new condensing boiler vents through plastic pipe, the old chimney may need a liner for the water heater left in it. Wisconsin requires working CO alarms on every level, so test them whenever a boiler is serviced. A boiler visit looks at system pressure, the expansion tank and the circulator, then finds which radiators stay cold.

Boiler service in Prescott: questions
Do Minnesota utility rebates apply to a boiler in Prescott?
No. Prescott is in Wisconsin, and its gas comes from St. Croix Gas, which takes part in Focus on Energy. Focus on Energy is the statewide program to check first. Some rebates have contractor requirements, so ask whether the rebate needs a registered contractor before you choose equipment.
My old Prescott chimney drafts badly on cold mornings. Is that a boiler problem?
An unlined chimney can be a problem for a new boiler in Prescott. Tall, unlined chimneys in the older houses cool off and draft poorly on the coldest mornings, and that can send flue gas back into the basement. We inspect the chimney and the boiler's venting, and we make sure the CO alarms on every level work. A liner or a switch to plastic venting may be the fix.
