HVAC Buddy® App 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!!!!!!

    By Jst4funn
    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.
  • No longer useful

    By StevenThatcher72
    Without the diagnosis tab to give recommendations of what's wrong, I have no use for this app. My digital gauge set does all the things this current version of the app does. Please bring back the diagnostics. The help section is just an advertisement for another app and is not telling me anything about how to use this app. Disappointed
  • No more Great app!

    New update 👎🏼. Complicated. Sencilla eficaz y fácil de usar, solo necesita mas refrigerantes.
  • HVAC Buddy R-4

    By Car-rel
    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

    By Smokingdodge
    Just tried the new version and miss the old style.
  • Old one had red to green good/bad indicators it was much more helpfull to techs and customers

    By Sfcahr
    Also no diagnose advice in new one no instructions for the silly graphs Red green idiot lights to signal a go nogo status are better
  • It was good

    By Mp4545
    The most recent update has a fancier look but is less useful than the old version and seems half finished
  • Read the reviews!!

    By Hvac provider
    App really disappointed me with the lack of refrigerants. At least state a list of them on the description details. Missing a lot of refrigerants like 407c,422 and many more. I mean I really wanted it for the refrigerants I don't normally come across and need a idea of the pressure.
