Furnace Services in DeMotte, IN: Repair, Tune-Ups & Replacement

Gas, Electric and Propane Heating for Northwest Indiana

Furnace Service Before and After the Cold Arrives

Most furnace calls in northwest Indiana arrive in the same two weeks: the first genuinely cold night, when a system that has sat idle since March is suddenly asked to run. Krooswyk has been on the other end of those calls since 1988.

We install high-efficiency Armstrong Air furnaces and repair every major brand. Northwest Indiana homes run on a mix of heating fuels and we service all of them, from natural gas furnaces in town to the propane and electric systems common on rural properties outside the gas lines.

Frequently Asked Questions
Furnace Repair and Installation

  • My furnace turns on and then shuts off after a minute. What causes that?

    Frequent cycling on and off is one of the most common furnace problems we are called about, and it often traces back to ignition components such as the igniter or flame sensor, or to restricted airflow from a clogged filter. Because furnace faults can involve combustion safety, it is worth a diagnostic visit rather than guesswork.

  • Do you service furnaces that are not Armstrong Air?

    Yes. We work on every major furnace brand, not just the Armstrong Air equipment we install. Our trucks are stocked with the parts that fail most often, so many no-heat calls can be resolved on the first visit.

  • Do you repair electric and propane furnaces as well as gas?

    Yes. Natural gas furnaces are the most common in town, while many rural properties outside the gas lines rely on propane or electric heat. Each type has its own failure points, and our technicians are trained on all three.

  • How often does a furnace need a tune-up?

    Once a year, before the heating season. Annual service includes burner cleaning, heat exchanger inspection, and safety control testing, which is not something a homeowner can verify without the right equipment. It also keeps manufacturer warranty requirements satisfied.
