No one else had an opening for that day. I've had 3 different repair people out to find why i wasn't getting heat and Kendall found my breaker was melted and broke. A great company that knows their business.

We are customers of Diamond Air and did not hesitate to call them. Excellent service, we knew we needed a bigger unit and that was one of the items they mentioned right away, and put in an extra air flow which was needed. All you have to do is contact them, talk to them, and you are sold.

D & C Wileman    Seguin, Tx   

We have been Club Members with Diamond Air since July, 2008 and they have always given us good, dependable service on a system they didn't install. What really impressed us was
1. Spring/Fall reminder notices to call and schedule a seasonal maintenance for cooling/heating.
2. Their professionalism and care while working inside and outside your home.
3. Their attention to detail and making sure the systems are working properly.
4. Giving thorough instructions for operating the systems and ensuring you are satisfied with the job.
I would highly recommend them to anyone.
