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.

Tech was on time, very professional. Found that out condenser fan motor was going out and went to the A/C parts store to get one but did not have it in stock. He called me and let me know what the ETA was for the part. Love to communication.

Was very surprised they could repair our system the same day. Tech evaluated the issue then provided us a detailed explanation of the problem and the repair cost. Our system was fixed the same day 🙂 thank you.

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.

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!!

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.

Great experience with Roy and his installation team who installed 2 brand new Lennox HVAC systems in my home. All three men were polite and expedient. They installed and got the main system up and running on day one, and the upstairs unit on day two. They took care of everything from start to finish. In addition both systems came with smart thermostats, in this case ECOBEE4, that have incredible features. I would highly recommend contacting Roy with Blue Diamond Air for any HVAC concerns including getting a new system.

After having another company come out and advise me I had a slow leak and due to it being R22 would need to consider replacement, I contacted Diamond Blue to see if they could repair leak to get another year out of unit. They responded to advise me that there was no leak, the R22 was full in the unit and it was operating efficiently and effectively at the time of service. I was relieved that a new unit was not quite necessary at this time in complete contrast to the first company who came out two weeks earlier. I am getting 18 degrees temp differential, which was why I questioned first company in first place.I will not need to look any further for my future needs!Thanks guys!!PS: the technician Stephen! What a breath of fresh air. Knowledgeable, professional, helpful! What more can you ask for!

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

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.

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.

Darrius is so knowledgeable and professional and I’m so grateful for his help. Our AC wasn’t blowing out cool air late Wednesday night and he came out early the next morning and found we had a bad capacitor and replaced it on the spot. This is the second time I’ve used the company and both times they have been truly wonderful. Only AC company I will call when I need help.

Chance and his hard working crew did a great job! Our A/C went out the night of July 1st. I looked up A/C repair on Home Advisor the next morning and Chance was the first to call. He came over within 2 hrs. of our conversation. He quickly diagnosed the problem correctly, explaining everything he was doing along the way. He told me he could start to install both units 9 am the following day, July 3rd. He showed up promptly at 9. He said he had some bad news and good news. The bad news is the warehouse is closed for the 4th of July holiday. The good news is he paid the warehouse to open up so he could pick up the A/C units. However, the warehouse didn't have the unit in stock we had purchased. Chance being a man of his word gave me a free upgrade on the units so my family would not be without A/C on the very hot days that followed. 95 plus! Texas heat! The entire crew were great. One of them even bought my 2 kids ice cream from the ice cream truck that passed by. I am very pleased with the work that was performed by all the crew at Diamond Blue.

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.

I was very impressed by Darius and Simeon’s thorough services. They came to clean my air ducts but didn’t mind checking other plumbing issues at all without extra charge. My air ducts look so clean now! I highly recommend this great company.

I had a water heater that gave out on me and I contacted diamond blue for repairs. They were already on a tight schedule and booked for the week but they made the time to squeeze me in. That says a lot about how much they care about their customers. They came in and assessed the damage then told me what needed to be done. Also advised me what my options were. Anyways it was a great experience and i would definitely use them again!

Roy came out for my seasonal check, and noticed some unsafe issues. After all the headaches I experienced with my last AC tech I’m thankful DiamondBlue sent Roy. He was courteous, knowledgeable, and profesional! I’ve been in the rental house business for quite sometime, and you can’t put a value on having a good reliable AC tech!

I needed a 2nd opinion on replacing my AC. Diamond Blue Air sent Roy and Jody within 30min, and they found and repaired my system within the hour. I didn't need a $15,000 new system. The repair was actually still under warranty. I'll never call the TV guys again. Diamond Blue Air exceeded my expectations.
