HVAC Buddy®

HVAC Buddy®

Make your job easier with our handy
refrigerant charging and diagnostic HVAC app

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.

FOR EVERYONE

Evaluating a field service problem can be challenging but with FLEETGRID the equation becomes simple. First, we've taken a devide and concor approach by splitting our user base into 3 different senarios (outlined below: for companies, for pros, for homes) and providing a downloadable on-premise app for each group. Second, we provide an off-site cloud based application that is available for everyone to take advantage of (cloud.fleetgrid.com). Lastly, we tie all of this together by syncing data between applications, the cloud, and other third party services in a seamless way.
There a couple key differences between our on-premise downloadable apps and our internet based cloud app. Our downloadable apps function offline first so that means you can get the job done off-grid. The data on them is stored encrypted so not even we can see your data. They are also real-time and peer-to-peer so there is no central authority to get in your way. Our cloud based application, while it does require an internet connection, takes advantage of big data, machine learning, and other areas where a mobile phone or other device can't handle by itself.
