Getting an accurate System Performance Profile starts long before you check any live data — it starts with proper probe placement. In this clip, narrated by Roman Baugh, he and Adriel break down the setup mistakes that quietly wreck your readings when using the NAVAC SK4TPHM1 Smart Refrigerant & Air Side Diagnostics Pro Kit, from oxidation and rust interfering with pipe contact to air leaks around duct grommets throwing off your humidity measurements.
Sanding off oxidation, paint, and rust before clamping your temperature probes for solid pipe contact
Why five degrees of superheat versus twenty degrees comes down to proper sensor location and contact
Sealing test holes tightly around the probe stem to stop air leaks from skewing humidity readings
Avoiding contamination from attic air, crawlspace air, or air outside the building envelope during setup
How small setup errors can shift your wet bulb temperature and target superheat calculations by several degrees
Getting your Smart Probe Kit dialed in correctly on the front end is what makes the rest of your System Performance Profile trustworthy. Skip these steps and you're just guessing with expensive equipment.
