Chapter 01
What actually fails on a Wisconsin furnace
Most of the calls we run in January come down to a short list of the same failures. A cracked heat exchanger. A failed inducer motor that won't pull the draft the burner needs to fire. A flame sensor fouled by a season of dust, so the unit lights and then shuts itself back down. A blower that runs and runs and never actually reaches the temperature on the thermostat.
We test for the actual failure before we quote anything, on any make or model, not only what we sell. That's the same testing and diagnostic work we run on boilers, heat pumps and oil furnaces, and it's why the quote you get from us is usually the one that holds.

Repair or replace, said plainly
The honest version of this decision weighs the age of the unit against the cost of the fix, not a sales script. A ten year old furnace with a bad igniter is a repair. A twenty five year old unit with a cracked heat exchanger is a different conversation, and we'll tell you that straight.
If somebody else already quoted you a replacement, bring us that quote. We offer a free second opinion on any HVAC estimate you've been given, and we'll tell you if it holds up or if there's a cheaper way to get the same result.

What we install and why
Rheem is our main line for furnace installs, and we also handle Olsen Airco oil or gas furnaces when that's the better fit for the house. For hot water in-floor heat, we install Crown Boiler Co and Triangle Tube boilers, which is a different job entirely from forced air and one a lot of shops don't touch.
For a garage or a shop that just needs to be kept above freezing, we install Modine unit heaters, the kind you'd mount overhead rather than run a duct system for.
Zone control
If there's one room in the house that's always cold, usually a bedroom over the garage, the fix isn't a bigger furnace. It's a zone control system that lets that room run on its own thermostat instead of sharing one setting with the rest of the house.
We size and install these as part of a new system or add them onto an existing one, so the room-to-room complaint actually gets solved instead of worked around with a space heater.
