    Reassurance My Furnace Is Maintained
    Glad to have reassurance that my furnace is maintained and I won’t have any problems.
    Carol Bode
    Great Service!
    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 well as too. My service fee was $100, which I won't 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 I'm 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 fraud 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! I've 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. Needless to say, got Bel-O programmed in my phone for this summer coming up! Thanks again y'all! Great service!!

    5 Plus Stars for a Job Very Well Done
    Mr. Anthony Horstmann was very professional and had a friendly, customer-oriented attitude. He took the time to explain in very easy and understandable terms what was wrong with the heating unit. I give him 5 plus stars for a job very well done. We were extremely satisfied with his work. Highly recommend Bel-O for your heating and cooling services.

    Timely and Thorough
    Timely and thorough. Just waiting on follow-up estimate to complete the repair following the diagnostic appointment. Good experience.
    Jo Sevin
    Great service experience!
    My heat stopped working, and when I called, they had someone out to check it within a couple of 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 30 min. He gave preventative recommendations to consider for the future with no pressure. Great service experience!
    Sarah Beaver
    Would Definitely Recommend Them
    Called the company yesterday and scheduled an appointment for today. John came out a little earlier than the scheduled time (which is always awesome). He came in, asked a few questions, and took a look at the issue. About 20 minutes or so, the sink was back up and running (literally 😂). Would definitely recommend them for services.
    Ryan Taira

    Prompt and Quick Service
    Anthony from Bel-O Heating and Cooling was prompt on his scheduled time and he resolved our issue quickly. He vacuumed out our gas fireplace and we are waiting to hear back about an estimate to install a blower. Thank you again for your quick service. Anthony was very polite and hopefully we'll see him again on the blower.

    Top-Notch Service and Reasonable Price
    Bel-O has been a trusted HVAC supplier for many years. Our water heater reached its end of life on a Saturday afternoon. I called Monday morning and got a same-day appointment. The technician showed up an hour early, and we had a new water heater before I finished work. Top-notch service and reasonable price - especially for same-day response.
