"I have nothing but good things to say about Philip Mills, his crew, and his company, Cassana HVAC. I wanted to install heat-pumps for central heat and air in my large home, and I solicited a few bids. Philip responded promptly to my request to visit my home and provide a detailed estimate. His price was quite competitive, the work started on time, and he and his crew did an excellent job. Indeed, I am so impressed with Cassana HVAC that I am now using them to work on other systems in my home. I highly recommend Philip Mills."

"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"Superior Comfort has a superior team. Zoher Zach Hariri recently handled our seasonal service. He did an excellent job. He is clearly an exceptional technician. In addition, it shows that he cares in customer satisfaction. Superior designed and installed our entire HVAC system a few years ago. It works great and they do a fine job keeping it working great."

Customers say: Terrific value
"My central A/C failed during this heat wave. After numerous calls to companies having to leave messages, not answering the phone, having to wait two weeks for service or companies not taking new customers, I finally found Rodney owner of RJP HVAC. He answered the phone himself, and told me he could be at my house in two hours! I received a text when he was on his way and promptly arrived. He quickly diagnosed the problem, explained what he could do to fix it and gave me a price which was surprisingly reasonable. I gave him the go ahead and he fixed the issue within the hour. He is very friendly and professional. I highly recommend him and will call him for all my HVAC needs going forward."
