The problem
You’re on a wet rooftop, torch in one hand, and you hope the joint you just made won’t send the customer a bill months later. That tiny black scale you can’t see can break a compressor or clog a valve weeks after installation and force an expensive return trip. Small contractors and lead installers lose hours, parts, and reputation — ACHR News and HVAC trade forums show brazing without nitrogen purges still happens and can cost a four‑hour callback plus a $1,200–$2,500 compressor or part replacement (ACHR News; HVAC forums). Training or post-job flushing doesn’t guarantee removal of baked-on scale, and existing tools are mostly flow meters or visual indicators with no time-stamped job proof to show a manufacturer or homeowner. WHY NOW — heat pump shipments and installations have surged and manufacturers are stricter about install proof, so the risk of warranty fights and smaller internal passages clogging is growing (Air-Conditioning, Heating, & Refrigeration Institute shipments and RMI/ACHR News coverage).
