"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"We just had a new HVAC system installed in our home in Aliso Viejo. The contractor was Cool Air Technologies, Bill McIntosh, (714)863-0626. We were very impressed with the new unit put in the attic and back yard, the workmanship, the professionalism, the quick response time to get our appointment, the testing of the new units before they left, the lessons for us on how to use it, and the complete clean up and hauling every piece of the old unit away when they left. They even installed new air vents/registers in every room and air filters! Very impressive and highly recommended to everyone! [*** Link removed ***]"

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."

"George is a true professional. He very patiently explained several options for replacing my hvac system. In the end I hired another pro for my project, only because they have been maintaining my system for many years. I would definitely consider George and SO CAL BOYS HEATING and AIR in the future."
