• I feel working with Stephen he is very accessible, takes the time to explain the issues. I am very technical so I like to know all the operating parameters of my systems. He is patient with me and I learn a lot. Provides sage advice. Very responsive to calls, repairs, etc. Sometimes able to service same day a need arises. Very well mannered and respectful of people, dogs and property—my lab loves him. I feel I can trust him to do good work and is honest about what it takes. I do wish the prices were lower, but I get it is not easy to run a business with all the overhead, cost of equipment, tools, refrigerant, etc. However, I have not found their pricing to be much higher than other established companies. I do feel their subscription service for twice yearly maintenance service on my two units is a great value. Stephen goes through an extensive list of items to check which is time consuming but ensures AC is ready for texas heat. He has been a good advocate for me on warranty claims with Amana—new compressor and system board replacement. In one case where an Amana warranty replacement compressor was making a loud thump, he was able to install a MicroAir soft start and the thump went away. A much cheaper option then buying a new compressor.

  Dan Y.★★★★★

• The person they sent out to my home was Stephen, was very nice and knowledgeable. He did a great job and worked around our work schedule. He made sure to educate me so I knew what was going on with my unit and talked me through everything he would be doing to get it back to where it should be. Everything is running great now.

• Stephen at Diamond Blue Air is great, efficient, knows what he's doing and helps me each time. I've had to call him twice. Arrives when he says he will, got my AC working quickly. Also gave me a short term/long term plan since we all know HVAC problems could be pricey and the most cost efficient way to handle things. He figured out the warranty situation, is to the point, logical, and down to earth. He's also very nice and my very protective dog likes him too. Five stars :)

Because they have excellent customer service and are honest, which is rare nowadays. Stephen, who has been installing and servicing our HVAC units, is very knowledgeable and personable. Diamond Blue Air is blessed to have such good technician. I fully recommend Diamond Blue Air to anyone who needs a good AC company.

  Carl A.★★★★★

• Called Diamond Blue Air to get help for the AC Unit. Stephen is the one who turned up and am extremely happy with the support. Stephen is very considerate and not one of those who just wanted to get maximum buck out of customer’s pocket. He went extra mile to help with the refrigerant. And also showed willingness to help with issue should it occur again. Thank you Stephen (& Diamond Blue Air).
