These folks are wonderful. Super warm and friendly on the phone. The techs were timely, professional, knowledgeable, and wore shoe covers to keep our floors clean. They went over and above and spent a ton of extra time trying to diagnose the cause of my complex problem. I really appreciate them.

I am a little late writing this. Our compressor went out in August during one of the hottest weeks of the year. Our warranty company wouldnt do anything for 48 hours. We called Diamond Air, and they came out the same day, identified the problem, got us a quote, and helped us install window units to get through. We had to wait a few days to get the money to pay for a new unit and expected to be without air for a week or so. However, Diamond Air came out the next day, installed our unit, and let us pay them when the check came in. This is a company that cares about people, not just businesses. They will be my new provider for all my AC and Heating needs. I highly recommend them! Thank you for being there when we needed help!

Professional service. Previously, Rance and his son did great work and explained everything.Today, 26 Feb, the semi-annual tune up by Blain was nothing short of excellent. He was professional, understanding and did a fantastic job.

I get the same Technician pretty much every visit. He is always smiling, polite, and answers all my questions. Would definitely recommend the membership for twice yearly check ups

The epitome of a professional, efficient and honest company. Customer service is top-notch. Ben really cares about his customers. He is more than responsive, he is in constant contact through the process to assuage our concerns. Recently our a/c unit died. His quote out of several quotes we requested from different companies came in the cheapest, and he had it replaced with a new unit and up and running very quickly. In future, we wont be requesting quotes from other companies. Diamond Air is a keeper!

I have always received excellent service from Diamond Air. The servicemen are great - polite, responsible, and thorough. Was great to see Rance today. He is a wonderful serviceman and a strong Christian. Always kind and polite. Love him and love Diamond Air. Cant praise them enough. I feel very blessed to be able to call them when I need service. This time it was Saturday and the owner, Ben, came out. Thank you so much!!

They were a nice, respectful, professional and honest business. They provided a personal touch and I could tell they cared about our concerns and AC issues. They were a fair price and communicated with us throughout the entire experience. Our family will be using them for our AC service from now on.

Knowledgeable and always professional and are a good value. They are still a very good service provider. Good people. They installed a total home system a few years ago. That system is keeping cool and warm. It has not had many issues at all. They have a service agreement program. It pays for itself. They are a great value. If you want a reliable air and heating company, they are it. No buts or ifs.

Review 12 (2025-01-08 - Rating: 5)
The service was on time and for a service business, that is unusual. Nance explained all aspects of the tune up and advanced services. He was knowledgeable and patient with my questions.Both Rance and Angel worked steadily and efficiently together. It was a pleasant association with your company. I looked forward to having the service of Diamond Air.

For the second time in less than a year, Diamond Air has a done a great job on short notice. SHOUT OUT TO Rance. Every time he comes out hes efficient, personable, and prompt. Were glad we found this local company and are members. They are more than fair on pricing, and the customer care is PRICELESS.

Review 20 (2024-05-03 - Rating: 5)
Rance and Cayden were very professional. I felt very comfortable having them in my home. They were very honest about what needed to be done. (Just ended up needing Freon) And the company sent a text with a photo of Rance so we knew who they were sending before they they arrived. I fully recommend them to everyone. Thank you so much Rance and Cayden!

Review 22 (2023-08-10 - Rating: 5)
Called to set up an appointment to have unit looked at due to the amount of excessive days with temps in the 100s. Quick appointment turnaround! The technician was VERY friendly and informative. Explained each step that he and his associate would take to service my unit and make sure it was operating properly. The best part? They came with booties on their feet to protect my flooring without my requesting it! That meant they not only cared about their customers units, but their homes as well. Highly recommend Diamond Air!

We had to replace a 30+ year old gas HVAC system. Not an easy task as the old unit was located in a small closet space They did their magic and it turned out perfect. They were on time and were well prepared. Very professional, paid attention to detail, and very polite. Explained work in detail and answered all our questions. We are cool and happy! Thanks so much!

Review 26 (2023-06-21 - Rating: 5)
Can’t recommend Diamond Air highly enough! We came home from a vacation to our house temperature in the 80s. In a panic, we called a different company (won’t make that mistake again!) who told us we needed a full system replacement and that it would be between $13,000 and $14,000. We called Diamond Air the next day and they sent their tech, Blaine, out to look at our unit. He spent a ton of time throughly diagnosing the problem. The ultimate fix? Dirty coils, a new capacitor, and topping off our refrigerant. It’s been about an hour since he left and the house is already comfortable again. He also took the time to explain each issue, what steps he took to fix the problem, and why those fixes were needed. He gave us steps for preventative maintenance and double checked his work before he left. Thank you, Blaine and the whole Diamond Air team, for your kind professionalism, honesty, and integrity! I will never call another company for any heat/AC issue.

Review 27 (2024-05-20 - Rating: 5)

Review 35 (2021-05-24 - Rating: 5)
Ben Moreno at Diamond Air was top notch. I got quotes from 5 different HVAC contractors, 3 local and 2 national. Diamond Air not only had the best price, but also the best service.Ben was very responsive and honest and quickly answered all of my questions. He was also the only contractor to notice that there was an addition with a window unit and recommended bumping the unit up a half ton to push more air to that area. It showed that he cared and was paying attention to our needs.Once booked with Diamond Air they gave us a date and time and they were there like clockwork. The guys were extremely efficient and clean. They covered the floors and wore masks and could not be more polite. They also left some filters and have checked in to make sure everything was good.We started to notice a slight rattle, so we called and they sent someone right away. It ended up just being a couple of loose screws so they fixed it up and its working great.I would highly recommend Ben Moreno and Diamond Air.

Review 36 (2022-06-12 - Rating: 5)
One of the hottest days of the year so far and my AC system went down. Diamond Air sent out Rance and he got it back up and cooling lightning fast! Rance was very honest and answered all my questions. He even told me about their Club membership, a great savings since Diamond Air will be the only company that I use for my HVAC services. If you need a company you can trust, with great employees that take the time to do the job right, give Diamond Air a call!

Review 37 (2023-07-27 - Rating: 5)
Chelsey took care of our scheduling needs and very prompt! Blaine took his time to explain our problem, what would happen and what needed to be done to fix it. I also really like how they will call you to let you know theyre on the way. I will continue to refer my friends and family to Diamond Air over and over.

When I called to make an appointment, the technicians were able to come out the very next day. They were on time, very knowledgeable and professional. I had to replace a few parts on two units and pay for the service call. One of the technicians, Rance, told me about their Diamond Club plan and how much money it would save me even on this visit. The plan basically pays for itself. I was able to sign up immediately. The technicians were very honest and left everything very clean.It is refreshing to find genuine, hardworking, people that offer good customer service! I’m glad to be a Diamond Club Member!

Review 41 (2018-03-01 - Rating: 5)
Since using Diamond Air I have had no problems with my service. I would not even CONSIDER using anybody else! Ben is always so thoughtful and caring about any questions or concerns. Rance is extremely great at his job,and has the most patience you can imagine! They are extremely polite and professional and are quick to be sure that I am comfortable with everything before they leave. Kudos...Kudos...Kudos to them and all they do!!! Great work...keep in doing what you do so well!

When another companys technician told me I needed to spend $1000 to repair my unit and then recommended replacement, I contacted Diamond Air for a second opinion. Rance and Blaine evaluated my system and determined it could be repaired for less than $400. They were knowledgeable, professional, efficient and friendly. I am now a Diamond Air customer.

Review 43 (2021-04-12 - Rating: 5)
Within an our of calling, Rance and Blaine were at our house checking out our ac unit. After diagnosing the problem they gave us the game plan and started working to fix the problem. This was seriously the most pain free experience we have had, when it comes to fixing issues with our house. We are happy with the work and grateful they fixed it so quickly. Both Rance and Blaine were professional and courteous. They explained everything to us and told us what to expect. We can’t say enough good things about the two of them. They were great!! Thanks for helping us out when we needed you!! They also mentioned the owners of the company were good people and they(Rance and Blaine)enjoy what they do. That made us feel comfortable signing up for the Diamond club membership.

Had my moms unit serviced 3 weeks ago and it was very low on freon so Diamond Air re-charged the system. I asked that they would come back and check to see if it is holding the charge. Everything passed the check out by Blaine. He as well as the owner and office manager are very kind and very knowledgeable with many different systems.

I give them a - 5 Star Plus!Ben came out; looked over what we needed and discussed what we were concerned about. Ben made the inspection a positive experience. He made us feel like we were part of a family. The Team arrived for the install and they were very professional and courteous to us and our home. They spoke well of Ben; how he ensures that they have time with their kids; which is very important. We are now COOL and comfortable, Thanks to Diamond Air. We are Happy that we now belong to the Diamond Air Family.

Ben was very honest and up front with us. He arrived when he said he would and worked in our house when it was full of kids and did not get frustrated or annoyed at all. He stayed on the jobsite while our new system was installed and made sure it was done correctly. Ben really seemed to want to help us and cared about us as a family. I would definitely recommend him to anyone out there from now on. Im glad someone recommended Diamond Air to me.

Diamond Air has been a wonderful company to work with! In addition to using them for my air conditioning maintenance, I decided to install a REME Halo whole home in duct air purification system. What a wonderful difference this has made already in the air quality of my home! I love animals and have a dog and cats living with me. I hate the thought of my house smelling like my pets and often worried that guests would be able to smell animal when they entered my home. I can honestly say that now I do not worry about this at all and Ive even noticed that my seasonal allergies are much less bothersome. I highly recommend Diamond Air and the installation of a REME Halo whole home in duct purification system.

Review 60 (2022-12-02 - Rating: 5)
We are new to the area and found these guys via a quick online search for HVAC repair. When Diamond air showed up in the results two things caught my attention, they were very highly rated and had over 20 years in business. I called them soley on those two factors alone. I was called back within about 45 mins by the technician assigned to the issue. He was extremely respectable and punctual. He showed up when he said he would. He troubleshot the system and called me with his findings and explained the issue in a manner I could understand (not knowing anything about HVAC myself). He went above and beyond what I initially asked that he look at and I was surprised when I got the invoice at then end of the call. What I expected to be several hundred bucks for a last minute call out turned out to be so reasonable (considering the times we currently live in) that I almost thought it was a joke and when I say that I mean the price they charged me was, in my opinion, completely fair and affordable. Businesses these days dont seem to follow that structure anymore. They try and nickel and dime you for everything youve got, These guys didnt do that. 100% satisfied and a customer for life. Thanks guys

I called and they set up a time that was I very happy with. They did all I asked and they set me up on a maintenance and discount program saving me money as of today. Rance also came in wearing his mask and shoe coverings and was kind while protecting my home and himself. Great Job and Thank you!

Rance and Blaine, Bens team from Diamond Air Texas came out and replaced my central a/c-heat system. they were respectful of my home(drop cloths everywhere they walked/worked), and since my install was fairly simple, there is no a/c closet due to ongoing remodel on my home, they were able to remove all the old equipment and install the new including some duct work repair under the home in less than a day. prior to the unit failure, they maintained the system for 20+ years till the unit was too old and inefficient to keep using. I have known Ben and Krista for over 20 years and the one thing that has not changed is the commitment to customer satisfaction. Give them a call and see for yourself. Derek H.

From the very first time I used Diamond Air they have been friendly, work done correctly, and respond promptly to emergencies. If they are running behind schedule they will call. I do not have one complaint.

Ben, Rance and Ray at Diamond Air in Seguin, Texas are probably the best HVAC professionals in central Texas. I live in Austin, an hour from Seguin, and they arrived earlier than their appointment and got to work immediately. They completed the new install and removal with no mistakes the same day they arrived. The professionalism they exhibited when entering the house was immediately evident with dirt free, clean shoes and safety mats for the floors. The new unit was a difficult-to-install type in a cramped attic space. The work is done so cleanly that one would think it was original to the house and not a retrofit in tight conditions. Rance and Ray are informed and friendly technicians who do not mind sharing tips and pointers that help keep your furnace alive for longer. I know I could have chosen a HVAC service in Austin but the price Ben offered was competitive and fair, really too good to pass up. If you live in San Antonio, Austin or one the surrounding cities along the I-35/I-10 nexus do not hesitate to call Ben or Krista for your HVAC needs. They really are the best.-Roland Blumberg

Rance Carroll came out to review why my unit was not cooling. Let me preface this by saying I have AHS Home Warranty and whenever I have a problem, I contact them first since I pay a deductible and they repair. This past time the problem was not fixed so I called Ben. He had his men come out and immediately they resolved my problem due to shoddy work performed by the other contractor. Diamond Air will be the FIRST call I make from now on! Thank you gentlemen for making our home cool again!

Our A/C unit stopped working and after calling 2 other companies, both saying we needed a whole unit replacement, Diamond Air came out and found it only needed a burnt out terminal replaced and a capacitor replaced. Saving me a difference of $7400. They will be my go to A/C Specialists from now on.
