What we see in Shorewood homes
Shorewood is densely built: duplexes, Tudors and Colonials from the 1910s through the 1930s on narrow lots, plus apartment and condo buildings. A large share of these homes still heat with hot-water or steam boilers and radiators, many of them decades old.
In duplexes, the upper flat often has its own boiler or furnace in a shared basement, and the upper unit is usually the one that runs hot in summer. Narrow side yards and tight basements make equipment placement and venting the real design problem, not the equipment itself.

We fix it, test it and clean up

Good to know
Shorewood questions we hear most
Can I get air conditioning in a Shorewood home with radiators?
Yes. Ductless mini-splits are usually the cleanest way: a few quiet indoor units, small refrigerant lines and no ductwork through plaster walls. In some houses an attic air handler with ducts run through closets works too, and we show you both options.
Our steam radiators bang and some never get hot. Is the boiler bad?
Usually not. Banging and cold radiators on steam systems are most often vents, pitch of the pipes or water level problems. We check those before anyone talks about a new boiler.
How fast can you get to Shorewood?
Shorewood is about 25 minutes from our South Milwaukee shop. No-heat calls usually get same-day service, and the emergency line is answered 24/7.
