Diamond HVAC

Diamond HVAC operates as a licensed mechanical contractor and builder serving Grant, Newaygo, and surrounding Michigan communities. The contractor holds State of Michigan mechanical licenses across five distinct areas of HVAC, a residential builders license, and maintains six certifications from the Michigan Propane Gas Association. With a 5.0-star rating from 16 verified reviews, the business has built its reputation on responding to homeowner needs across heating, cooling, water heating, and water treatment systems.

What distinguishes Diamond HVAC from neighboring contractors is the breadth of credentials held by its team. The business owner carries both a certified home inspector designation and multiple propane gas certifications, enabling the company to handle complex installations involving LP gas, natural gas, and electric systems. Beyond standard heating and cooling work, the company installs water softeners, water pumps, and on-demand water heaters that homeowners can consult about to potentially reduce utility expenses.

Reviewers consistently highlight specific scenarios demonstrating the contractor's commitment to resolution. When one customer's glass door panel was accidentally damaged during AC installation, the technician returned to repair it at no charge. Homeowners report same-day responses to inquiry messages, with installation timelines as fast as three days from quote approval. One reviewer noted their equipment has performed without problems for seven years following installation.
