"I had a great experience working with Cool Air Technologies. Bill and Trish McIntosh are fantastic. Great personal service and super friendly. When I first met Bill, I explained to him that I had recently purchased a new home and was in the process of making some upgrades to my existing home so I could covert it to a rental. I didn't have any air conditioning so that was my priority but I was considering replacing the original furnace at the same time if the price made sense. However, I didn't want to invest in a high end system since I wasn't going to be living there myself. Bill quoted me a great price for the A/C and new furnace so it made financial sense to do them both at the same time. One of my other quotes was literally double for the same scope of work. Bill came in with his crew and they were professional and efficient and completed both A/C and furnace installs in about 7 hours, including running all new piping and electrical for the A/C. I would absolutely recommend Cool Air Technologies and the personal service that Bill and Trish provide and I will definitely be giving them a call in the future for my new home. Thanks Bill for the great work!"

"I was out of town when my air conditioner stopped working. My mother called 2 companies to check it out. The repair men were interested in selling us a new unit not fixing it. I found NT Electric & HVAC online through Home Advisor while I was out of town. The company had good reviews. I called Nathan and scheduled an appointment. He assessed the problem and fixed it! I would highly recommend Nathan and his company. He does what s best for the customer. His prices are fair and reasonable. I would use him again."
