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.

Back to my #1 go to app!!!!!!

I have been a fan of this app since 2012, but was disappointed when the diagnostic tab was lost in the facelift. But you listened, and corrected the issue, almost overnight! Great job, and thanks for being so responsive. I highly recommend this, and all this developer's apps. They stand behind their products, and great customer service. Well worth the price.
