Best Thermostat Installation in Milwaukee WI

The team was absolutely wonderful. As a first time home owner, I wasn’t sure what all was happening when my furnace stopped producing heat. Dan was wonderful and providing diagnostic advice until Anthony was able to come and see the equipment. Anthony was nice, professional, knowledgeable, and was able to solve the problem within the hour. Highly recommend.

Omer went above and beyond to make sure I understood all the components of my furnace and heating/cooling system that I had not known about my home . I am confident that everything was thoroughly evaluated! I would highly recommend him to family and friends.
Thank you for being so professional and informative. 5 stars!

My family has used Knauer for a variety of services for over 50 years. We have always been very satisfied with their professionalism, helpful suggestions, and prompt service.

Highly highly recommend! After calling multiple places on a 90 degree day with our AC out at our business, they were the first one who could come out the same day. They came quickly and were very friendly and professional and knowledgeable. They were able to fix the problem that day. I’m so glad I found them so I don’t have to call multiple places for same day service

I have worked with JM Brennan on many projects and their dedication to customer service is top notch! They have developed a culture at their organization that is second to none in the Mechanical Contractor space. Their prices are fair and transparent and the staff does a great job of presenting the appropriate sense of urgency!

My mom exactly 1 month ago had a service call on her 2 yr old furnace, and then yesterday her furnace had the same problem, the other company which starts with B when my mom called again had such an attitude and complained he hasn't seen his wife real long so they didn't come out. My mom had no heat. I THEN CALLED CLIFF BERGIN HEATING TODAY AND THEY WERE FANTASTIC . THEY CAME OUT WITHIN A COUPLE HOURS AND FIXED THE PROBLEM AND WERE VERY CONCERNED ABOUT NO HEAT IN MY MOM'S HOME. THIS COMPANY IF I COULD GIVE MORE STARS TO I WOULD .GREAT GREAT COMPANY.THANK YOU FOR EVERYTHING YOU DID FOR MY MOM.

Anna in plumbing was very helpful !

Great team that did a fanatast8c and professional job installing my new AC unit..I will recommend them to others.

Even took the time to lay down blankets so their shoes wouldn't dirty up my floor.

Thanks all!
