iPhone app HVAC Buddy®

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 its just a couple taps to send a personalized report.
