Why Oakland and Macomb County Customers Call Sandison
Michigan Licensed Mechanical Contractor
Sandison holds Michigan mechanical contractor licensing covering plumbing, HVAC, and related systems. When you call us, you are working with licensed professionals — not unlicensed subcontractors.
Mechanical Engineering Background
Our technical foundation goes beyond trade certification. A mechanical engineering background informs how we diagnose complex system interactions, size equipment correctly, and identify root causes rather than symptoms.
Advanced Diagnostics & Thermal Imaging
We use advanced diagnostic tools, including thermal imaging, to identify issues that visual inspection alone cannot reveal — hidden leaks, insulation failures, electrical hot spots, and heat-transfer anomalies.
Residential, Commercial & Institutional Experience
From single-family homes to commercial facilities, our team has worked across property types and system scales. That breadth of experience means we bring the right approach to every job.
