Matt Laub

Craig and his assistant were very courteous. Took caution when moving equipment and tools through the house. Did an excellent job communicating with us about the work and then asked us to inspect it after they were finished. Great job! Thanks Matt

I had the unfortunate situation of my furnace quitting on me. To make matters more serious, it happened right before the first real winter storm to hit in the Midwest ( January 2026). With the help of A.I., I singled out Bel-O as the best company to call for this issue. I made a call and between 2 visits my heat in my home was restored. My inducer was the problem, so they ordered a new one and installed the new inducer in less than 30 minutes. Both servicemen that visited my home were friendly and professional and even checked the other components of my furnace to make sure those parts were working good as well. My service fee was $100, which I wont cry about at all for facing not having heat right as a severe winter storm is about to start. Since the new inducer was installed, I noticed that my furnace is a lot quieter than before. I wonder if the excess rumbling was a sign the inducer was about to quit working? If I hear it again Im definitely calling them. So far, no issues and my home is warm again! I also like that there are payment options with this company. They accept most debit and credit cards with a visa or mastercard logo. Cash and check are accepted and payment is due at the moment service is completed. If you cannot for some reason pay at that time, they can help you to set up payment arrangements to cover the cost. You can also directly pay via their website. I had a hiccup paying them at the moment service was done because my bank thought it was fruad because of the amount ($1728), so I used their website to send in my payment without fuss! A minute later my receipt from Bel-O came in my e-mail confirming they received the payment and that was it! Ive already told a few people who own their homes about Bel-O as a good hvac service is seriously needed when you have heating or cooling issues. NeedIess to say, got Bel-O programmed in my phone for this summer coming up! Thanks again y'all! Great service!!

My heat stopped working and when I called they had someone out to check it out within a couple hours of me calling. The service tech was very respectful and explained everything he was doing. It was a simple repair and after double checking the system would continue working he was here and gone in less than 30min. He gave preventative recommendations to consider for the future with no pressure. Great service experience!

Anthony was fantastic. From the moment he knocked on the door he was nothing but kind and professional. He came in worked on our furnace, gave me a very informative explanation about what was going on with our unit. Payment was requested and handled in a very professional manner. It was an excellent experience as always.

?????????? Service Provided: Gas-Fireplace Cleaning, Tuning and Maintenance. I had an excellent experience with Bel-O Heating, Cooling and Plumbing thanks to technician Jim Gauch. From the moment he arrived, Jim was professional, courteous, and extremely knowledgeable. He took the time to carefully explain what needed to be done, answered all my questions, and made sure I fully understood the work being performed. Jim’s attention to detail and thoroughness really stood out—he didn’t just address the immediate issue, but also checked the system to make sure everything was running efficiently and safely. His expertise gave me complete confidence in the service I was receiving. Bel-O is lucky to have a technician like Jim representing their company. I truly appreciate the outstanding service, and I wouldn’t hesitate to recommend both Jim and Bel-O to anyone needing reliable heating, cooling, or plumbing work.
