What we see in Wauwatosa homes
Tosa has some of the best-preserved 1910s to 1940s housing in the county, and a lot of it is still heated by hot-water or steam boilers with cast-iron radiators. Those systems last a long time but need real boiler knowledge, not a furnace tech guessing. We also see plenty of homes where someone added forced air decades ago with undersized ducts, and second floors or finished attics that never cool properly.
Mini-splits, properly placed, solve a lot of that without tearing up plaster. The postwar ranches west of 76th are mostly conventional furnace-and-AC setups now on their second or third system.

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
Wauwatosa questions we hear most
Do you actually work on steam boilers?
Yes. Steam and hot-water systems are a regular part of our work, including radiator vents, traps, low-water cutoffs, and full boiler replacements.
What is the best way to add AC to an older Tosa home with radiators?
In most cases a multi-zone ductless mini-split system. It avoids running ducts through finished walls and lets you cool the rooms you use. We lay out head locations with you before quoting.
How quickly can you get to Wauwatosa?
Typically same day for no-heat and no-cool calls. Call and we give you a real window, not a guess.
