Member Spotlight on Aliance Heating & Air Conditioning, LLC

By Tara Williams

Honesty. Transparency. Fairness.  These are the words Bill Tomaszewski’s team uses to describe what makes their business rise above the rest. Tomaszewski has found success in operating his business, Aliance Heating & Air Conditioning, LLC. since 2018, using the Golden Rule. 

“He really treats people the way he’d like to be treated,” says his marketing manager, Danielle Miller, adding, “If you don’t need something done, he won’t recommend it for you.”

Tomaszewski agrees, saying, “I always tell people, ‘This is what I would do if it was my house.’ I won’t sell you anything I won’t put in my own house and that they don’t need.”

While 80% of his business comes from the 5,000 doors he services through property management companies down in Milwaukee, Tomaszewski has a new goal.  He and his wife, Loren, have lived in Belgium for more than ten years and are focused on building up their base of residential customers closer to home.

“We love where we live,” he says.  “I always go local and like to feel a part of the community.  We’d like to do more here.”

Tomaszewski has gotten involved by joining the board of the new Rocket Academy, the tech charter school being built in Belgium.  Exposing high school students to the trades is a passion of his.  He attended Custer High School in Milwaukee, a trades high school, and took his first HVAC class at age 15. His brother-in-law served as a mentor to him in the years that followed and he’s been hooked ever since. 

He’s enjoying helping the board form the curriculum for the new school and hopes to help get kids out in the field to learn and eventually work.

“There’s a big need for the trades,” he says.

His team of ten does it all, from selling and servicing furnaces, boilers, air conditioners, heat pumps and filtration systems to performing duct cleanings and tune ups. He carefully selects his products- saying about 80% of his installations are Goodman, a brand he appreciates due to their solid warranties and the fact that they are 100% American-made and assembled.

Aliance Heating and Air Conditioning will always provide inspections and estimates for free, and assures its customers that they will always get the best price up front- no negotiating.

“You want a good company to work with, and I want good customers with long-term relationships,” he says.

The Tomaszewski’s are also driven by their faith, and it is important to them to “never turn a blind eye to those in need.”  Every year they not only keep items such as protein bars, water and socks in their vehicles to distribute to the homeless, but also try to pick one family in need each year to provide with a new furnace, free of charge.

“You can always gain monetarily, but spiritually, it feels good to help people out,” Bill says.  “We let God lead us, and we go where he leads us.”
