About OnPoint HVAC: Licensed HVAC Contractor Delivering Engineering-Grade Comfort for Metro Detroit Homeowners

ABOUT US

WE DON’T JUST INSTALL SYSTEMS. WE ENGINEER THEM.

When you invite an HVAC company into your home, you're not just buying equipment... you're trusting someone with your family's comfort, safety, and peace of mind. That trust is exactly why OnPoint HVAC exists.


Our founder, George Petrentzev, is a mechanical engineer by trade who spent nearly 20 years in the automotive industry before realizing that his true passion was in construction. In 2016, he launched OnPoint Construction, which quickly became known for its quality work and unwavering attention to detail. But as George spent more time in the field, he kept noticing the same problems play out across Livonia and Metro Detroit: mechanical contractors cutting corners, doing quick equipment swaps, and calling it a day. Systems were installed fast and "repaired" forever.


Equipment passed inspection on paper but never actually performed. Ductwork was slapped together with foil tape instead of built with the craftsmanship homeowners deserve. The same story played out with plumbing and electrical work... expedited installations that looked fine on the surface but left homeowners dealing with leaky connections, faulty wiring, and systems that never quite worked how they should. It was clear that corners were being cut across the board, not just with HVAC.


By the time he was called in to evaluate these situations, homeowners were already frustrated, stuck with brand new systems that still left the master bedroom freezing and the living room stuffy. With his engineering background and years of hands on experience in everything from tricky residential retrofits to complex mechanical builds, George knew homeowners deserved better. Not just equipment that ran, but systems that were designed, calculated, and installed with real precision. Systems that quietly and reliably do what they are meant to do, season after season.


So he founded OnPoint HVAC with one clear mission: to bring engineering level accuracy and integrity to everyday homes, and to treat every project like we're installing it in our own house. In just two years, that mission has shaped everything we do. From the brands we choose, to the way we plan and build mechanical rooms, OnPoint HVAC exists for homeowners who are done settling for shortcuts and ready for comfort that's actually engineered to perform. Reliable by design. Exceptional by choice.

HVAC Project Management & Engineering-Grade Installation
In the HVAC construction industry, the roles of aConstruction Manager,Project Manager, andSite Manageroften overlap but have distinct focuses. Project management primarily emphasizes planning, scheduling, budgeting, and overall project coordination, ensuring the design, procurement, and compliance aspects align with project goals. Site management, on the other hand, focuses on on-site activities, including workforce supervision, safety enforcement, quality control, and daily task execution. The overlap occurs as both roles require collaboration to address installation challenges, maintain timelines, and ensure the system is installed per design specifications, creating a need for close coordination between planning and on-site operations.
