Make your job easier with our handy refrigerant charging and diagnostic HVAC app - HVAC BuddyÂ®. If you are servicing equipment the best way to begin diagnosis and determine the proper refrigerant charge is to use HVAC BuddyÂ®, a set of gauges, and a thermometer. - Superheat for fixed capillary or Subcool forTXV/EXV systems - Calculates targeted vs. actual Subcooling - 4 refrigerants including R-22 (Freon), R-410A (Puron), R-404A, R-134A - Airflow / Delta-T / TEET Calculation - Diagnosis tab for leaks, overcharge, contaminants, etc. - Email System Status Report - Imperial (IP) or Metric (SI) - Use Target Superheat and Subcool tables or enter manually - Update all values with realtime output - User friendly with step by step instructions if the early outdoor temperature is 75F and you charge the system to a â€œbeer can coldâ€ suction line your system is likely improperly charged. Later in the afternoon high temperatures will increase head pressure and the resulting overcharge means a lower than desired superheat and wasted energy. Not good! Overall Process: - Enter refrigerant, temps, and pressures - The math is done for you to display Superheat, Subcool and Airflow Target, Actual, and Difference - Email all readings (detail) Other Features: - Flexible units - psi, kPa, Fahrenheit, Celsius, etc. - Calculates Superheat and Subcool targets - Airflow - For cooling, compares a targeted difference across the coil vs. actual. Also called Delta-T or Target Evaporator Exit Temperature (TEET). - Diagnosis - shows common causes for high and low superheat, subcooling. - Instructions - Detailed step by step instructions and knowledge base at powertrade.com/support. - System Status Report - Use the email tab to create defaults for email addresses, subject, and System Status Report introductory text. Tap the email button and these values are incorporated into a formatted page including all the parameters recorded in HVAC Buddy. Edit the email and / or add contacts from your contact list. Then on each service call it's just a couple taps to send a personalized report.
