I’ve been using Greentech for tune-ups since last year, and they’ve consistently been excellent. Kendrix serviced my heating system today and was very professional, taking the time to answer all of my questions. Great company!

I purchased this house in July of this year, and shortly after, my system started leaking refrigerant. I contacted several contractors for quotes and possible solutions. After doing my research, I decided to go with Greentech Engineering Heating & Air Conditioning.
I chose them for several reasons:
Transparent Pricing: Their pricing and proposed solution were very reasonable. There were no hidden charges and no hassles throughout the process.
Right Solution, No Upselling: The solution they provided met our exact needs without any unnecessary upselling. Thank you to Shen Chi and the team.
Excellent Communication: Their communication was much better than other local businesses, and they even offer weekend support.
Punctuality: They arrived on time for both the quotation day and the installation day, which I really appreciated.
Attention to Detail: Some contractors walked on my floors without shoe covers, but Shen always arrived prepared with shoe covers and was consistently polite and professional. During the HVAC installation, the team used mats to protect the floors.
Overall, I am very happy with their service.
