Description

Make your job easier with our handy refrigerant charging and diagnostic HVAC app - HVAC Buddy. If you are servicing equipment the best way to begin diagnosis and determine the proper refrigerant charge is to use HVAC Buddy, 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 beer can cold 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.
