Our Customers Say It Best

Steve did an excellent job with our clothes dryer repair. He got us back up in running in short order. I never realize how much we use a particular appliance until it is not functioning.

I look forward to the next time I can count on Bell Heating and Air, LLC for help!”

Bradley T.

Found Bell Heating and Air LLC when looking for companies local to the Wausau, WI vicinity. Contacted Steve, and has been great to work with so far. Steve arrived on schedule, no lack of communication, and was knowledgeable enough to match the best replacement just from a image sent via text. Currently replacing our HRV that had a dead motor. I will provide a quality review upon completion.”

Travis M.

100% recommend! Steve helped us with a boiler that suddenly conked out on us. He was quick, efficient, and professional. The price he quoted is what he charged. I know a few other people who have all used his services and they were so appreciative of his skills. In this day and age when you can’t rely on people to show up when they say they will, Steve far surpassed my expectations. Thank you!!!”
