Unit heater
A Modine hung in a shop ceiling
Not every job is a house. Garages, shops and outbuildings get unit heaters run off the same gas line, mounted out of the way of the work.
Kimberly, Wisconsin · 123 S Railroad St
Furnaces and air conditioners for the Fox Cities, out of the same Kimberly shop since 1978.
Bob and Mary Nennig started this in their garage. Their son and daughter in law run it now, with eighteen people and twelve trucks, and somebody picks up the emergency line at two in the morning in January.

The photographic appendix
Work that came off those twelve trucks
Real installs from around the Fox Cities, pushed sideways as you scroll. No stock equipment, no stock basements.
Furnace
Rheem Prestige, finished basement
High efficiency gas furnace set square, ducted clean and left with the venting tidy enough that the homeowner can still use the room around it.
Service tag
The tag on the duct
An older basement, an older furnace, and our tag on the ductwork. Plenty of these are systems we did not install and have kept running for years.
Delivery
Coming off the truck
Twelve service vehicles run out of Railroad Street. Replacement day starts with the new unit on a dolly and ends with the old one gone.
Condenser
Outside, against the foundation
Pad set level, line set run and sealed, disconnect within reach. The part of an air conditioning job the homeowner actually walks past every day.
