About Us

We’ve been keeping homes comfortable throughout Milwaukee since we started out in 1957.

When you’ve been in business for more than 60 years, you learn a thing or two.

Tri-Town Heating and Air Conditioning has been servicing the home comfort needs of families in Muskego and Southwest Wisconsin since 1957. We bring honest work, great service and up-to-date industry knowledge to your family. In fact, we’re dedicated to it.

That’s because we’re family, too.

Chuck Hoormann started Tri-Town back when the name referenced the three communities we served then—Muskego/Hales Corners, Franklin and New Berlin. And as Southwest Wisconsin has grown, so has our service area and our long line of trusted employees.

Chuck’s son, Bob, took over Tri-Town Heating and Air Conditioning with his wife Sandy in 1980. And these days, Bob’s son, Craig, oversees most of the business.That history of experience can also be seen in our technicians. They bring nearly 40 years of industry knowledge and skill to their work.

We work on all major heating and air conditioning makes and models and are pleased to offer a wide range of innovative Lennox® products to keep your HVAC system running efficiently and reliably. And, just like family, we’re there for you when you need us with 24/7 emergency service available.

Find out what sets us apart from the competition and why we’ve been a Muskego institution for more than 60 years. Call Tri-Town Heating and Air Conditioning today at 414-422-1620.
