My wife and I own several rental houses plus our home and Diamond Blue Air and Heating have installed several new systems and have been servicing our HVAC units for several years. The reason is simple. They provide exemplary service!I fully recommend them

I had a unique problem with one of my new units. After several visits, and contacting the manufacturer of the unit, Diamond Blue successfully traced down the issue, and repaired it, at no charge to me. They could easily have charged me labor for the trips they made, but they did not. In my opinion, this is tremendous customer service and sorely missed in our current environment.

I have used Diamond Blue for several years for my A/C service and maintenance. They are quick to come to our house when we call. The service is always thorough and complete. I like the fact that the same service men are grouped by area so we always have familiar people. Great company!

Got an appointment quickly and tech arrived on time. He promptly inspected our system and made recommendations consistent with another technician we had look at the system. Wish I had called them first.

Steve is just amazing, always on time and customer service obsessed. Very honest teamwork and the service is super awesome responsive and customer focused. thanks for helping me out so quickly and efficiently.

They came out super-fast and fixed our broken a/c ON A SUNDAY. Stephen was very professional and knowledgeable. We’ve had another service for 20 years but are switching to Diamond Blue Air.

Absolutely recommend! Scheduling was a breeze and they were able to come out bright and early the day after I called to fix our furnace. Stephen was on time (even a few minutes early), very nice and respectful and always put shoe coverings back on when coming into the house. He explained everything simply to us and recommended a pest company for a few rodent issues he saw. The easiest process and so quick! Will absolutely be calling them again for future issues

Stephen B. is a highly skilled and detail-oriented HVAC technician. He is very knowledgeable and honest when it comes to the work he does. I’ve recommended him to a few people and have heard great feedback. I will continue to request him for any HVAC work I need done.

Diamond Blue Air = Rock Solid quality service and nice folks! Stephen was polite, professional, self-aware, knowledgeable and efficient when diagnosing and replacing the fan motor for our outdoor condenser. I am a “service member” to what is possibly the largest HVAC / Plumbing / Electrical company in Dallas County and they are quickly pricing themselves out of my home (story continued on their site!). Diamond Blue Air will take good care of your HVAC at a price you’ll be happy to put to comparison. Keep up the great work Stephen!

Excellent service from Stephen. Took the time to listen and fully diagnose with me there. Provided a solution and executed on the fix promptly and fairly. Highly recommend.

I would highly recommend Blue Diamond Air for all your heating and AC needs. Stephen was outstanding. Very prompt and did a great job.

Stephen is very responsive. Same day service several times for when AC was not working. Good at finding and showing issues. Replaced condenser. When I had grinding noises from new unit he quickly responded and fixed.

I used two contractors from home warranty for the heating issue. One said I need to change the zone panel without checking anything. The second guy said it is an airflow issue and he can’t help. Stephen from Diamond Blue Air is excellent in explaining about the airflow issue and he fixed it in no time. I will use them again in the future.

Stephen is highly knowledgable and really takes time to explain stuff when we got questions. He has been looking after our HVAC system for a year and we are planning to switch to DIamond Blue Air for our rental property too. Really good service and very professional. Would highly recommend to anyone looking for HVAC maintenance and repair.

Great customer service. The technician was able to come out a few hours within calling while other companies had a wait of over 2 days. Highly recommend

We are currently in the process of evaluating the various quotes from HVAC companies so I cannot comment on the end work just yet. However, I want to express my extreme gratitude to Diamond Blue Air for promptly returning my call and inquiry, as well as being on time (actually a little early). Mainly, I want to thank the tech, Stephen, who went through all our concerns, provided multiple different options and ideas to help save us money and headaches in the future. He went out of his way to go through every aspect of our complex commercial system and hear our concerns. He was professional and based on our time with him, would recommend this business to all!!

The Best in the Business! Stephen does great quality work and I highly recommend Diamond Blue Air!

Stephen is super knowledgeable and always try’s to do everything he can to get a system running. In the event it needs to be replaced he always try’s to give the best deal possible.

I recommend Stephen and Diamond Blue for all your HVAC needs. Speedy and reliable service without breaking the bank.

Unlike other companies Blue Diamond Air has not lost the true meaning of customer service. I use them for my primary and rentals. I work with Stephen every time. Customer service is in his DNA and if you want to get down Into the coils this guy will give you page numbers or product numbers out of a manual without opening a book.

Stephen at Diamond Blue Air exceeded all my expectations! His exceptional customer service and attention to detail truly made my experience outstanding. He went above and beyond to ensure that I found the perfect product, and his knowledge and expertise were invaluable. I highly recommend Stephen to anyone seeking top-notch service at Diamond Blue Air. Five stars all the way!
