Boiler Repair & Service in Eagan, MN
Eagan boiler service is a $79 trip charge up front, waived when you say yes to the repair. Most Eagan homes heat with forced air, but we service the hydronic systems that turn up: slab heat, combi boilers and combination water-heater systems.
Boiler service calls in Eagan homes
The hydronic work we do see takes a few forms. A walkout lower level or a heated garage may have radiant tubing in the slab, fed by a compact boiler, or even a water heater, through a mixing valve and pump. Now and then a house or townhome is on a combination system, where a water heater or boiler feeds a hot-water coil in an air handler, so the blower is moving heat that came from the water heater. And newer combi boilers heat floors and make domestic hot water from one wall-hung unit.
Slab loops, combi boilers and combination systems share the same weak points: air in the loop, a failed circulator, a stuck mixing or zone valve, and a garage loop whose antifreeze has broken down. If you've inherited a radiant system with no labels, we trace it and label every zone.

Boiler service in Eagan: questions
Our Eagan garage has in-floor heat. What maintenance does the loop need?
A garage loop usually runs antifreeze, because the slab can freeze if the heat source stops. That fluid breaks down over the years and should be tested for freeze protection and acidity. We also check system pressure, the expansion tank, the circulator and the mixing valve, and look at the boiler or water heater that feeds it. A yearly check makes sense for a loop that runs all winter.
Which gas utility's boiler rebate applies to my Eagan home?
It depends on your address, since CenterPoint Energy, Minnesota Energy Resources and Xcel Energy all deliver gas in Eagan. CenterPoint's heating rebates cover high-efficiency boilers and let you use the heating dealer of your choice, and Xcel's rebate list has included gas boilers too. Check your gas bill, then that utility's current page, because programs and rules change every year.
