I did not follow through with this company to purchase my new ac unit system but the sales rep that was working with me was super professional, outstanding, and took care of me as if he was family. I can certainly say their commitment to the customer is legit and their prices and estimates were not astronomical compared to the competition. 10/10 if I didn't have a better offer come through from a family friend I would of went through with this company. Scott Hearing was amazing!

Everything from start to finish was pleasant and professional. There were 3 rounds, a service person to check things out and to make a recommendation, a sales person to confirm and go over pricing options, and then a 2 person installation crew. All were very nice and respectful of our home. They confirmed and kept their appointment times. I would definitely recommend this company.

Disclaimer: This review was written only a day after installation was completed. The Custom Air team was extremely helpful, friendly and seemed to be very knowledgeable as well. Scott was our sales rep and he did a comprehensive review of our current air conditioning and heater system before recommending how to move forward. He did a great job at explaining our options and getting us additional information when asked.
On installation day, without having to ask, the install team (Eli & Ryan) used shoe covers and drop cloths in the work areas inside the home. They introduced themselves and explained the process before starting and tested everything at the end. Overall we were very happy with the experience.

I've known the leadership team at Custom Air for years and they have always been one of the absolute best HVAC service and installation companies in the Columbus metro area. When I needed to replace my twenty year old system there was no doubt who I was calling. Stellar crew, and superior performance from start to finish. Service: Heating system installation
