HVAC technicians struggle to read model and serial number tags on outdoor units because they are weathered and sun-faded, making identification difficult.

TagGuard Inside

TagGuard Inside is a durable, adhesive-backed metal or weatherproof plastic tag that mounts on an interior surface of HVAC units. It contains a laser-etched QR code and human-readable model/serial number. When installed at the factory or retrofitted during service, it provides a permanent, fade-proof backup that scans with a smartphone or is easily read. This eliminates the need to climb ladders, clean grime, or decipher faded plates.
