What we see in St. Francis homes
St. Francis is mostly 1940s to 1960s Cape Cods and ranches, plus a growing number of condos and apartments near the lakefront and along Layton. The single-family homes are typically on their second or third furnace with ductwork that has been patched over the years; half-story upstairs bedrooms that are too hot in summer and too cold in winter are the most common comfort complaint, and they are usually fixable.
The lakefront condos bring closet installs, association rules, and tight access, all of which we handle regularly.

How it works
What happens when you call A-1
1
You call or text, any hour
A person answers 414-595-5175, not a call center. We ask a few quick questions and give you a real arrival window, not a guess.
2
We find the actual problem
We test before we replace anything and show you the readings, so you can see what failed and why.
3
You approve a flat-rate price
You get the price before any work starts, with repair and replacement options in writing when both make sense. No hourly surprises.
4
We fix it, test it and clean up
Most repairs are finished on the first visit. We test the system, clean up after ourselves and explain what we did.
Good to know
St. Francis questions we hear most
How fast can you get to St. Francis?
Often within the hour for no-heat calls, because we are a few minutes away. In a cold snap it can take longer, so we give you a real arrival window when you call.
Can the upstairs of my Cape Cod be made comfortable?
Yes. Depending on the house it is duct balancing, added return air, or a small mini-split for the upstairs. We measure first and tell you which.
Do you work in lakefront condos?
Yes, including closet installs and the paperwork the association needs.
