All reviews for Greentech Engineering Heating & Air Conditioning

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.

Very good service. Very helpful to find the root cause of the heater's issue (cannot hold the temperature which was setup on Thermostat.).

Very impressed! from Greentech estimate to installation and review were so professional, prompt, courteous, and helpful. They did a great job installing new Daikin 2 stage 90% central heating and cooling system.

Zimeng was nice, responsive, interactive, professional and quick!!!😍😍😍😍😍💐 We’re back in business…. The heat and air is back on and I love my new thermostat plus I have the manual now. It looks nice plus it’s simple to use. He also showed me how to use it before he left.

Loved working Greentech Engineering! They came out the same day I reached out to them. They scheduled the work and completed within three days. I tried to work with two other companies that had us waiting over a week, with no communication. Greentech was responsive and kept us informed the whole time. 10/10 would recommend.

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.

My AC was making a very weird noise at condenser. I had two other contractors came 4 times and couldn't figure out the problem. And I paid $700 for nothing. Kai from Greentech Engineering came and spent almost 2 hours and found the issue was from the transformer in my furnace. After repair, everything runs perfectly! I paid them only $280 for the parts replacement. Don't waste your time and money to call some random guys who doesn't know what they are doing. Greentech is the right one to call!!! 100% recommend and will call them again!

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.

Greentech engineering has been so helpful and efficient in fixing our AC units. The price is very competitive and I would definitely recommend them to anyone! They are nice and always timely.

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.
