Ductwork Diagnostics, Sealing, and Repair in Oakland and Macomb County
Leaky or poorly designed ductwork wastes energy and creates comfort problems. Sandison diagnoses, seals, and repairs duct systems for better performance.
Ductwork Diagnostics and Repair
Studies suggest that the average home loses 20–30% of conditioned air through duct leaks. That means your HVAC system is working significantly harder than it needs to — and some rooms may never reach the right temperature regardless of how long the system runs.
Sandison's mechanical engineering background makes us well-suited for ductwork diagnostics. We use pressure testing and airflow measurement to identify leaks and design problems, then recommend targeted repairs.
