Residential HVAC Superheat & Subcooling Charge Verification Card

A field-ready, one-page-per-call job card that walks residential HVAC techs through superheat and subcooling calculations for fixed-orifice and TXV/EEV systems, logs refrigerant added or recovered by weight, and captures final sign-off conditions — all in one printable form. Print a stack for your service van and hand a completed copy to the customer or attach it to your invoice to document proper charge every time. Designed for R-22, R-410A, and R-454B systems; includes quick-reference target ranges and built-in PT calculation fields so techs do the math on the form, not in their head.
