Report
Had them out to my house in May give me an estimate and a diagnosis, gave me a diagnosis supposed to call me back about an estimate on how much exactly it would cost never called. So I didn't pay, came to my house today demanding payment, Not sure what company in the year 2020 doesn't accept credit cards apparently only cash or check.

Brian, Stuart and their team were great to work with as we were replacing the HVAC in an older home we were renovating. They worked with us on options to meet our specific budget and space needs. Everyone who worked on this project was very polite and knowledgeable of the specifics of the project. Thank you for a job well done!

Had difficulty with both the technician and the manager to the extent that I had to hire a different company to finish the job. Custom Air would benefit greatly if they had any concept of "The company works for the client, the client does not work for the company." Custom Air came out and didn't do what I asked and then argued with me about it, so I had to call another company to come out. The other company did exactly what I asked, the unit was fixed, they got paid on the spot and received a fantastic review from me.

Door sign says they are open, website says they are open. Door is locked and I have tried multiple times to call and just get busy signal. It's a Wednesday at 12:12. If they can't be dependable to keep their business hours then why should I trust them to service my heating needs?

Custom Air installed an air conditioner for my home. They arrived in a timely manner and made sure the job was just right. They went the extra mile to ensure that I was pleased with the job. Great job to Kevin and Denton and also to Brian. I am very pleased with their service and would recommend them highly.
