A short story about us
Our Founder, having worked at large Engineering consultancies for over 20 years, saw how profit-driven cultures compromised quality, leading to costly mistakes or overdesign. This inspired the creation of HVAC Consultants, which is part of Green Engineering Services.
”Every day, they strive to improve their service to the clients by developing the right blend of technology and creativity to make sure every job done is done as efficiently as possible.”
