HVAC reviews in Carrollton, Texas

Great work and very fast reactions. Strongly recommend.

This is a rental property, therefore my Landlord paid for the repairs. The service and technician was great!

Great Company! Courtesy! Knowledgeable about AC in and out! I had a weird AC problem. First, i hired a popular company , named some#1. They sent 3 techs and couldn't figure it out, and sold me unnecessary repair. Then i decided to try this company. From the 1st phone call to the follow-up, they were very professional! and did not trick customers with unnecessary repair orders. They explained the repair very well and did an excellent job at a reasonable price. I would recommend this company to anyone who wants a professional attitude and honest service! Thumbs up!

We recently had an issue where our second floor wasn’t cooling and no air was coming out of the vents. A friend recommended Greentech Engineering, and I’m so glad we called them!
Their technician arrived quickly and diagnosed the problem as a bad compressor and a stuck zone damper motor. They fixed everything efficiently and got our system running again.
What really stood out was how professional, honest, and straightforward they were—no upselling, just clear explanations and great service. If you’re looking for reliable HVAC help, I definitely recommend them!

Problem fixed!!! Thank you so much for listening and understanding what I’ve been dealing with. The system is now working fine and not going up to 82!! You also taught me some things in the thermostat I did not know . Very thorough and I won’t be bothering anyone again. Much thanks

Joshua was great on time and honest upfront got my heat up and running asap

I have been very pleased with the Techs and the service they provided in evaluating the problem, restoring the unit enough so we were comfortable until all parts needed came in to replace . I received text letting me know they were in route and all techs arrived on time, kept the work area clean and gave me step by step what to expect as they worked. It was a great experience.

One of.my unites stop working, contacted Greentech Engineering, they sent Kendirx Jennings who has been so helpful, with diagnostic, explaining the issue proposing the solution and improving it. This issue required multiple task to complete and Greetech was able to provide discounts for me on all three of jobs.
Now I am enjoying the cold air in my home

Just have my HVAC system replaced by Greentech Engineering. I’m surprised by their professionalism work and amazing customer service! Very satisfied and will definitely recommend!

This is a well run business. Extremely knowledgeable, thorough, polite, and on time. Had 2 units replaced - everything is working perfectly.

Excellent customer service. It was difficult process. However green tech beyond what they needed to do to make it doable as we waited for a part. I would highly recommend them

They earned 5 stars for communication, promptness, professionalism, and courtesy. I can recommend them with confidence and i will use them in the future when the time comes.

Super fast response. Diagnosed the problem quickly and solved within minutes. Saved the day on this super hot Dallas afternoon. So thankful for Joshua and his professional service.

Kai and Josh were awesome! Kai was able to come out the same day, explained the options and that they would be able to have the technician come out the next day. Joshua was friendly and knowledgeable. I definitely felt that they had my best interest in mind, and would recommend them to anyone needing help with HVAC.

I had a great experience with the technician who came to inspect my A/C today. He was very professional, knowledgeable, and friendly. He patiently answered all of my questions and helped me understand the issues with my system. I’m looking forward to having them back on Wednesday for the installation. Thank you for the excellent service!

Very professionally! Truly appreciated their service provided during and after the installation. Any concerns will be answered clearly. In particular, the co-founder Mr. Shen, he has super nice service.

My Air Conditioner is use by commercial Place , in passed few years all different kinds AC company come over replace or repair, they chance a lot also not good experience untill I find out Greentech Engineering company been use them for two years now and I decided to leave a review because sometimes you just get going with the company the first time the experience is great and the second one is not as good or the third one but every time they’ve came out, I’ve had a great experience. Everyone well communicative from the front office down to the technician. They’re very honest and they help me understand my air conditioner along the way great company and I highly recommend.

Lucas Chen was super helpful and knowledgeable and friendly and professional spectacular customer service.

I’ve been using Green Tech for years, and they’ve always been reliable, honest, and professional. Whether it’s routine maintenance or emergency repairs, their team consistently delivers great service. They’re knowledgeable, show up on time, and take the time to explain everything clearly. It’s hard to find companies you can trust long-term, so we’re grateful to have them. Highly recommend!

Joshua is great. He did the job clean and professional. I would definitely use Greentech again.

We've been working with Greentech Engineering Heating & Air Conditioning for quite some time now, and they have consistently provided excellent service for our rental properties. Whether it’s installing new AC units or handling repairs, their team is always prompt, professional, and reliable.

They’ve helped us with several installations and repairs over the years, and each time the job was done efficiently and with great attention to detail. Their technicians are knowledgeable and courteous, and they take the time to explain the issues and solutions clearly.

As a property owner, it’s a huge relief to have an HVAC company we can trust. Highly recommend them to anyone looking for dependable air conditioning services.
