Top-Rated Energy-Efficient HVAC Solutions - Designed for Comfort, Built for Sustainability.

Greentech replaced air handler for us. There were noise from the motor at the very beginning. I called them and they sent technician at first place. The noise problem got resolved. I am happy with their professional service, especially their professional way to work with their customers to get problem resolved. I have peaceful mind when working with them.

I've been a repeat customer for years. I also referred them to my parents' home to fully replace their A/C system and their quote saved them thousands. We're so grateful that their technicians are honest, straight forward, and provide transparent and ethical pricing. Any time our heating or AC has gone out, they've been able to fix it the same day that they come to investigate.

I highly recommend Lucas for any HVAC needs. His combination of excellent customer service, skilled technicians, and fair pricing makes him a top choice. My compressor is now working flawlessly, and I couldn’t be more satisfied with the whole experience.

They’re very professional could not fix my unit because I did not have the part so hopefully they will be back tomorrow to fix it. Gosh, I hope so. Cause it is one hot house right now.

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.

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.

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

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

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.

Just want to thank this company today for coming out fixing my AC Unit.  It went out yesterday put in a request yesterday, out the next day and fixed! Truly appreciate the quick response and the quick time the maintenance man did while here. AC unit back up and running right before summer hit soon enough!
