HVAC reviews in Carrollton, Texas

Stephen showed up promptly with great communication. Really took the time to connect with us as a customer, and listen to where our concerns were. Stephen took the time to inspect our entire A/C unit, took pictures of all areas afterwards and did all sealing and maintenance needed. Highly recommend using this company.

Excellent customer service from the first phone call from Chance, to the air duct cleaning from Darius and Simeon! They were helpful in explaining every detail and very professional and courteous. I highly recommend this company for any services that they perform! They went above and beyond to make sure they did the job right! Would give them 10 stars for sure!

My ac was not blowing cold air and I was hesitant to call anyone to come look at it. I looked up A/C repair on Home Advisor and made the call. Much to my surprise, from the initial phone call until the job was finished I had a great experience with excellent customer service.
Stephen arrived promptly and did a precise evaluation of the problem. He was very knowledgeable, professional, and courteous explaining every detail.
Will definitely use them again and I highly recommend them. Would give them 10 stars.

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.

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!!

Unlike other companies Blue Diamond Air has not lost the true meaning of customer service. I like working with Stephen. He cares about making the customer happy. I thought good business ethics no longer existed. Diamond Blue Air proved me wrong.

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.

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

The company was recommended to us by a family friend. Darius was extremely professional. He was knowledgeable of the service and products that they offered. He discussed different options and we felt very comfortable with what he shared. The customer service went above and beyond by ensuring that our system remained functional until replacing. I love the companies protocol for ensuring their technician safety as well. Thank you so much.

My wife & I have been quite pleased with our interactions with Diamond Blue Air. Jerry Hicks, the owner, was congenial and helpful. Rick, the manager, promptly and courteously responded to our need for help with our central AC system. The technician, Darius, who arrived at our house soon after our call, was courteous, agreeable, and efficient. He was competent and effective at evaluating and remedying our problem. He repaired only what was necessary, and the cost to us was very reasonable. Diamond Blue has earned our confidence and trust.

Can't say enough good about Stephen and Diamond Blue Air. They have been on time, fair pricing and upfront on servicing our A/C and the maintenace contract.

Diamond Blue and Stephen are always prompt, professional, thorough, and reasonably priced.

Steven is an excellent Technician. He was able to explain the diagnosis in detail and potential next steps to permanently fix the problem.

Excellent Service! Would highly recommend Stephen and his team!

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!

Professional, efficient, and very knowledgeable. Highly recommend their team for any commercial HVAC needs.

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!

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!

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.

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.

Stephen is always on time friendly and professional. We appreciate him taking time to explain things and advise us about our system. We highly recommend Diamond Air.
