    The owner, Jim, even called us Monday night to make sure everything was working and the house was cooling down.

I give them both 5 stars. But the company itself, I give 2 or 3 stars. My experience over the last year has been this: They book you 4 or 5 months out because they have too many customers and cannot handle the volume of clients they have and even then, they call the day before to try to reschedule your appointment.

    We started using Morrison Heating/Cooling, when they took over Meridith HVAC in Collinsville, at…read moreleast 10+years ago. Things started out really well; they installed a new furnace and then later a new AC unit. We were really impressed and happy with the company and their work, and their customer service was A+. We had the maintenance contract with them for years. Over the years, they did a lot of work for us. Besides the HVAC, they installed a hot water tank, new septic tank, plumbing (replacing pipes) and much more, we never had any complaint with the work or technicians. We would get the yearly maintenance checks for the AC, Heat and plumbing. Long story short, something happened, apparently Academy Air took over/merged with Morrison, I am not sure, because we were never notified. For the past year we had difficulty scheduling maintenance checks with them. I would call in April to get AC check, and they would say nothing available until August, (so what's the point) same with HVAC winter check. We had the Plumbing check last summer, and Academy Air came out, and told us we needed $20,000 in replacement work on faucets, etc. we declined. Our maintenance contract expired in April and we have not heard from them, crickets. We now use another company and are very happy. I just wanted to put it out there, that we do not recommend Morrison Heating and Cooling (Caseyville). Stay away or use caution!!

    Moved into home about 45 days ago with new furnace that was installed over the summer. I had…read moreinitial questions about the unit. Called Bel- Air multiple times in September without answer to either phone number from the original invoice. Verified against Yelp and listed numbers online. Voicemails left without return. About 2 weeks ago, turned heating on. No warm air flowing so tried contacting again without answers. Contacted a different HVAC company who saw burned wiring requiring replacement parts. Fortunately parts were included under warranty but Forced to pay labor costs. Now they noticed there is a wiring issue where the initial set up that was done presents a fire hazard. An electrician has come out and says that separate wiring needs to be ran in order for the voltage to be safely transmitted. This was probably avoided before because of the extra steps and cost. But if this isn't fixed, the same issue could arise with burnt wiring and possibly start a fire in my house. At this point I'm so disappointed that a company would do this. It's the last thing I should be worrying about as I am moving to a new area and starting a new job.

    I asked 5 contractors to give me estimates on a new air conditioner system. I'm glad I decided to…read moreask one more contractor. Number six was Bel-Air heating and cooling and I hired him on the spot within the first 3 minutes of meeting him. The work started the next day and by the end of the day around 4:00 p.m. my system was up and running. The guys did a great job, price was very reasonable considering the amount of work that had to be done. Now all I hear is my Honeybun complaining she's cold. I HIGHLY recommend Bel-Air heating and cooling and when my furnace needs replaced I will definitely call them. My system is only 3 to 4 weeks old but is getting a good workout going through this heatwave and so far my system Rocks!!! Recommendations from people are not given they're EARNED so do your research. I did and it paid off. GREAT JOB Bel-Air Heating and Cooling!!!!
