Description

Make your job easier with our 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 Subcooling forTXV/EXV systems
• Calculates targeted vs. actual Subcooling
• Over 100 refrigerants including newer azeotropic blends
• Airflow / Delta-T / TEET Calculation
• Email System Status Report
• Imperial (IP) or Metric (SI)
• Use Target Superheat and Subcooling tables or enter manually
• Update all values with realtime output
• Line Chart displays historical values based on input changes or elapsed time

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, Subcooling and Airflow Target, Actual, and Difference
• Email all readings (detail)

Other Features:

• Flexible units - psi, kPa, Fahrenheit, Celsius, etc.
• Calculates Superheat and Subcooling targets
• Airflow - For cooling, compares a targeted difference across the coil vs. actual. Also called Delta-T or Target Evaporator Exit Temperature (TEET).
• 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.

HVAC Buddy R-4

The new version of HVAC Buddy R-4 has a screen capture issue. While the capture shows up in photo's, if you try to import it into "Invoice 2 Go " all you get is a black screen. Screen capture can be texted however.
Anyway to roll back to old version?
Also all contact options on web don't work.

Miss the old interface
