62 Gravois Rd, Fenton“I have used Hely Heating and Air Conditioning for over 30 years and have received exceptional service. I purchased my current AC and furnace, as well as my current water heater through them. They did many repairs on my previous 30 plus year old unit to keep it running until I could afford to replace it. The workmen are always courteous and efficient. I would highly recommend them to everyone needing service. It is refreshing to see a company that delivers quality service and stands behind their work. I would never use anyone else.“

1315 Missouri State Rd, Arnold“After having Marciante Diversified to my house for a furnace issue I mentioned wanting to get A/C and heat installed in two rooms of my house. They suggested going with Mitsubishi mini split HVAC systems. Marciante is a Mitsubishi Diamond Star dealer. I did some research and found that these systems were highly rated. I asked for an estimate and decided to go for it!I can not begin to tell you how happy I am with the systems and the installs! Their attention to detail and the quality of their work is outstanding! They do what they promise to do. Plain and simple! I would recommend Marciante Diversified for maintenance on your home HVAC systems as well as Mitsubishi mini split installs.! Thank you Marciante Diversified! You've got my business!“

A couple years ago, Randy replaced the ac/furnace unit at our home so I knew who to call when our shop furnace went out.

4736 Happy Ln, Arnold“I have used Controlled Heating and Air conditioning for all my AC needs. Back in 2021 I had a flood in my basement and they came out and replaced all my components. Fast forward to this year I had them come out and tune up my AC and they found my evaporator was leaking. They where able to replace it quickly before the heat of Summer. The system is running great. Karen and Jeff thank you so much for taking such good care of my family and I.“

Their work has always been cost effective and done by people that have a great understanding of various construction activities. There have been minimal call backs when something was not quite right and they always stood behind their work. Their communication is always timely. It always felt like they were that family member that just knows how to do everything that I can’t and willing to lend a hand.“

Since the moment Ive called to make an appointment for a bid until the moment it was installed . They even did a follow up a month later. Came and looked at it to make sure that everything operates , and was done properly . Not to mention, they were a lot cheaper than the other companies Ive called. Their technicians are professional and polite. I have nothing , but good things to say about this company.“
