Furnace and AC repair in Delafield, WI
Delafield’s growth took off after I-94 reached the area in 1963, leaving a mix of older lake-area homes around Lake Nagawicka and subdivisions built from the 1960s on. We find the real cause and give you a flat-rate price before any work starts.

What we see in Delafield homes
Delafield became a city in 1959 on the shores of Lake Nagawicka, and its biggest growth came after Interstate 94 reached the area in 1963, turning it into a bedroom community for Milwaukee and Waukesha. The houses split the same way: older homes near the lake and the original downtown, and subdivisions built from the 1960s onward. Lake-area homes that started as cottages often carry ductwork added over several remodels, with the rooms at the end of the run the ones that never keep up.
The subdivisions from the 60s through the 80s are commonly on their second or third furnace, and many added central air afterward on ductwork that wasn’t sized for it. Newer construction near the edges of the city usually runs one builder-grade system for the whole house, which tends to leave the upstairs warm in summer.

How we work in Delafield
We find the real cause before we talk about parts, whether it’s a lake cottage that grew one room at a time or a subdivision house on its original ductwork. You see the readings, you approve a flat-rate price before any work starts, and new equipment is sized with a load calculation instead of guessed at.

You approve a flat-rate price

We fix it, test it and clean up
