Inspections are critical in HVAC work because they ensure that systems are constructed properly and that safety regulations have been met.
Inspectors search for leakage in the system, especially around connections that require several pieces of tape. Air leakage can result in high utility bills and system failure down the line that may require contractors to rework the system, costing them time and money, and potentially damaging their reputation.
During the inspection, the HVAC tape is checked for UL compliance. HVAC tapes that are UL listed have been put through a series of rigorous tests to ensure they meet the requirements for safety and performance, and are designed to resist burn, mold, and humidity.
Ultimately, HVAC work is inspected to keep all of us safe.
