## What is TunePro HVAC/R?

Turn HVAC/R readings into clear diagnostic direction with TunePro. See live gauges, grade superheat and subcooling for the system in front of you, review likely causes, and move directly to the next useful check.

BUILT FOR THE SERVICE CALL

• View live pressure, temperature, superheat, subcooling, saturation, and air-side readings in one organized workspace.
• Apply system-specific charging guidance for TXV and fixed-orifice equipment, including target superheat calculated from return-air temperature, humidity, and outdoor temperature.
• Follow ranked diagnostic findings with the supporting readings, field context, and practical checks behind each result.
• Compare multiple evaporators on one suction line with Multi-Superheat mode.
• Track evacuation progress with live micron readings, pulldown trends, and standing vacuum decay analysis.
• Use a fast pressure-temperature calculator covering 30 refrigerants, including R-410A, R-32, R-454B, R-22, R-404A, R-448A, R-449A, R-134a, R-290, and R-744.

CONNECT YOUR FIELD TOOLS

Connect supported Fieldpiece, Testo, Parker Sporlan, Yellow Jacket, and NAVAC instruments over Bluetooth. Mix supported brands on the same call and bring every reading into one view. Manual entry keeps familiar gauges and instruments in the same streamlined workflow.

READY WHERE THE WORK IS

Core measuring, charging, diagnostic, PT chart, vacuum, and history tools run directly on the phone. Keep the call moving in mechanical rooms, basements, rooftops, and other low-connectivity locations, then continue with the same saved work when coverage returns.

FROM JOBSITE TO CUSTOMER

Organize sites, equipment, readings, and photos for the whole crew. Each saved reading carries its technician and time, giving the office and every truck a consistent equipment history. Create clear customer reports and send them by link or email from the completed call.

TunePro keeps the readings, reasoning, records, and customer handoff together from the first measurement to the finished job.
