About
greentech engineering

We are a 100% family-owned and operated company, proudly serving our clients with two distinct but equally important services: HVAC solutions and Engineering Consulting. Established in 2020, after gaining over 6 years of experience in the HVAC industry, we set out to simplify the overly complicated sales process commonly found in this sector. Our approach is straightforward and honest, focusing on being experts in air conditioning rather than salespeople, ensuring a hassle-free experience for those in need of reliable HVAC contractors.

I called Greentech for double check if I need a new furnace as another company recommended. But, after their technician checked, they said my furnace is working properly now. No need to replace a new one. They spent time, but they didn’t charge me. Their working standard is high. I trust them. If I need a new furnace, I will use Greentech! THANKS!
