"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"I'd become increasingly concerned about the company I was using for my AC and heating needs. When I knew we needed a lot of work doing, I decided to search for a new company that I could trust. We needed to get 4 new AC units installed. They were 17 years old and leaking, so we took the plunge and decided to replace them. I had a lot of questions around the systems in my house and what to install. During my phone conversations Donny was extremely helpful and patient. He answered all my questions and I believe that he gave me honest suggestions on the best solutions for my home and living situation. I found him to be honest, trustworthy and very knowledgeable. The install went smoothly, one of the units was tucked away in a tight closet in my daughters room, and they dealt with that easily. They installed 4 new controllers. They were tidy, and worked long hours to get the job done. In addition they spent time explaining the new systems to us and answering questions of ours that arose. We are really pleased with the new systems and controllers, we have peace of mind that we've installed good, reliable systems, and that we have a great company looking after our AC and heating needs. I also hired them to do annual service visits for our heating and AC. So far they have performed the winter maintenance visit, and identified a couple of things that needed addressing to prevent possible problems this winter. What they recommended made sense to us, and we thought they were valid and worthwhile repairs. As we trust this company, we decided to go ahead and get the work done. Chris D came to do the repair job. He was very friendly, helpful, hard working, and did a great job. He also took time to make sure we knew what was going on. I'm hugely relieved that I found this company. It's increasingly rare to find companies to help out in the home who are good at what they do, honest and trustworthy. I highly recommend them. BTW I'm also impressed with their office support staff. They are super friendly and helpful, calling back when they say they will. Booking appointments is super easy with this company."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"The installation went very well. When a part arrived damaged, they discovered the issue and had a new one delivered within an hour. The installers were very conscientious and took precautions to avoid leaving a mess. There were two relatively minor issues that we became aware of after the installation and Bell came back promptly and fixed them without complaint. I don't have a good context for the price, but it seemed reasonable in the context of my neighbor's installation and my previous dealings with them on service had been good."

"My technician was very honest. Upon evaluating my AC he said I didnâ t need a repair or replacement but instead I needed to keep the AC at a consistent temp & keep window units on upstairs to supplement a system not designed to cool the whole house. I paid $133 for his service trip and that was all."
