HVAC reviews in Charlotte, North Carolina

What a wonderful experience!! Reny came to our home, analyzed the problem, explained to us the cause of the problem, and fixed the problem. Super professional and knowledgeable!!

Reny was awesome! He did a wonderful job with replacing the motor in the HVAC system and went out of his way to help me clean my vents. When he first came out, he did not have the motor but kept me up to date on when it was arriving and when he'd be able to install it; superb communication.

Awesome customer service, fast and friendly very knowledgeable even assisted with replacing my air filters for me due to me not having a ladder to reach it. Provided education on what was going on. Helped me last year with another issue I had with the ac unit as well. We need more people like him and the company he works for that love their job. And has great customer service

Rene and his team are very quick, professional and knowledgeable! You can trust you are getting incredible service and they care about their customers. Support local and use Rene and his team for any of your HVAC needs!

Reny was fantastic! He was so responsive, professional and knowledgeable. Reny is probably the best service technician we’ve dealt with in any service over the years! The system required 2 trips to fix because of parts ordering and diagnosis but we never wondered when scheduled appointments would occur - he kept us informed and updated during the entire process and even contacted us to check that everything was working ok.

We have had several problems over the years with our AC unit. Technicians were always coming here and getting it to work fora little while and then it would stop. It was a blessing to meet Remy, he replaced our 1st floor unit and it has worked wonderful from day one. This year our second floor unit went out and he came again and ended up replacing that unit as well. Now our home is like walking into a freezer and we’re loving it. Call them for your repairs/replacement you won’t be sorry. And Remy deserves more than a 5 star, he’s an awesome person too!

The HVAC Tech sent by Delta T, Reny, was incredible efficient and personable. He was able to identify and repair the issues with my HVAC system in no time at all. Highly recommend.

Thanks to Reney as he was very professional in providing excellent service repairs to my AC/HVAC. Was on time and very responsive to answering questions and fixing the issue. Highly recommend!!

I had the opportunity to have technician René in my house to accommodate my air and the truth is that I could not be more satisfied with his work, excellent service, excellent attention, excellent work and really grateful!!!! I will always keep Mr. René and this company in mind for future problems. 5 stars

Reny was very thorough and made sure our air conditioner was working properly before he left…very nice person as well!

Great service! Remy did a safety check on our system and did a wonderful job. He did a complete check and thoroughly explained the process. We needed a couple of repairs and he took care of all of it on the spot! Would highly recommend!

I had a challenging set up as the indoor unit was over 25 feet from the outdoor unit.
Reny did excellent work. He installed my system in a timely manor and explained how the unit worked.

He went above and beyond installing a special drain for me and filled out the form for my warranty. I would highly recommend their services.

I’m very impressed with Delta T Mechanical Systems! We called them for an urgent HVAC inspection after noticing a gas smell, and they responded quickly. The technician was not only thorough and professional but also incredibly personable, making sure we understood everything along the way. Their efficiency in handling the situation put our minds at ease. If you need HVAC services, inspections, or repairs, I highly recommend them—reliable, knowledgeable, and truly dedicated to great service!

Excellent customer service, excellent communication of what’s going on and what time they’re gonna be here. Stayed way past normal hours to get the job done greatly appreciate it. Good job Reny.

Thank you so much!! Reny my HVAC technician arrived quickly to diagnose my AC! It was found to be leaking old Freon and let me know the state of the unit. Within a few days I had a new AC! He and everyone else involved was professional and quick! I highly recommend this company to anyone that needs repairs or is looking to replace their unit. I myself used to do HVAC work and was very impressed with him, the company and the overall install.

Reny was quick, professional, and a pleasure to work with. Great communication and he had our AC back up and running in no time. 10/10 would recommend!
