Our Services

At H&M Mechanical Group, we pride ourselves on our expertise in various services, including Heating, Ventilating, and Air Conditioning (HVAC) design, Plumbing design, Energy Analysis, and Fire Protection systems. We understand the importance of considering factors such as budget, type of occupancy, and energy usage when designing a system. Our team is well-versed in the latest design technologies, including Leadership in Energy and Environmental Design (LEED), Collaborative for High Performance Schools (CHPS), Green Point Rating, and CalGreen.

Innovative Approach

We are committed to staying at the forefront of design technology, ensuring that our services are always up-to-date and relevant. We replaced our traditional hand-drafting methods with AutoCAD and later integrated Building Information Modeling (BIM) using the Revit BIM platform. This allows us to provide our clients with the most effective and efficient solutions.

Our team is dedicated to providing prompt and professional communication, responding to all inquiries, submittals, and questions in a timely manner.
