"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"OCExcel did a great job replacing our old (25 year old) conventional HVAC with a new Heat Pump. They did it in one day, using a large crane. We are very pleased with the whole job and would completely recommend this company "

Customers say: Quick response
"Nathan is very experienced and knowledgeable. He responds quickly to every text and phone call. He and his crew show up on time, work diligently, are respectful, and focused, and do all the little details like caulking and matching paint. They installed a 5 unit mini-split system and totally completed in 2 days. The price was very good and he even passed on the incentive from the manufacturer. There are always unexpected hiccups in every construction / installation job and there was no complaining, no extra charges, he just handled them quickly and efficiently. All in all, excellent work, excellent service. We highly recommend NT Electric and HVAC."
