Charge Systems Accurately. Every Time.
The field-ready charging and recovery system for HVAC techs — superheat worksheets, subcooling quick references, R-410A tables, A2L procedure differences, recovery workflows, and ChatGPT prompts for accurate service calls.
Instant download · EPA 608-aligned · Superheat & subcooling tables · Recovery workflows · PDF + ChatGPT prompts
Overcharge a system by 2 pounds and it runs hot, wastes energy, damages the compressor. Undercharge and the evaporator freezes up — you get a warranty callback. The superheat and subcooling method is the only way to charge right, and most techs eyeball it. Stop guessing.
The Complete Charging Reference for Real Field Conditions
Complete Refrigerant Charging System
A practical field system for charging, verifying, recovering, and documenting refrigerant work without relying on guesswork or pressure alone.
- Superheat method (theory + field worksheets)
- Subcooling method (theory + quick reference cards)
- R-410A charging tables (pressure/temp at common conditions)
- A2L (R-454B) charging procedure differences
- Proper recovery & reclaim workflows
ChatGPT Prompt Templates

Built for Techs Who Need the Charge Right the First Time
The Service Technician
You handle everyday residential and light commercial systems where charging accuracy decides comfort, efficiency, and whether the job turns into a callback.
The EPA 608-Certified Tech
You already know the rules. This gives you the field method, tables, and recovery sequence to charge and recover refrigerant with precision.
The Senior Tech or Lead
You train apprentices and standardize field work. Give the team a repeatable charging method instead of a habit passed down by feel.
From Calls Where the Readings Had to Make Sense
“The superheat table changed everything.”
“I was shipping undercharged systems without knowing it. The superheat worksheet made me slow down, measure the right numbers, and charge the system correctly before leaving.”
David R.
Service Technician, Austin
“I wanted the A2L procedure before the call.”
“A2L charging is different enough that I bought this before taking my first R-454B call. The procedure differences and recovery checklist kept the whole job organized.”
Jennifer M.
EPA 608-Certified Tech, Denver
“It gave my apprentices a real charging process.”
“We use the quick charts with newer techs. They can see when to use subcooling, when to use superheat, and what readings actually point to a charge issue.”
Carlos V.
Lead Installer, Orlando
