Predictive diagnostics are arriving in the service trade the way remote monitoring did, as a dashboard flag that says something may be drifting. ACHR News covered Resideo's unveiling of an AI tool for HVAC diagnostics and maintenance. The product, Pro-IQ Predict, is described as "informed by millions of interactions with connected devices" and as an expansion of Resideo's Pro-IT services platform.
What the flag can and cannot tell you
A prediction is a comparison. A tool like this looks at a large population of connected equipment and flags a unit whose behavior is moving toward patterns it has seen before. That is useful for a company managing many systems. It does not describe how your air handler, your duct run, and your attic behave on a warm October afternoon. The summary does not explain how the scoring works, so treat any alert as a question for the technician, not a verdict on the compressor.
Build your own baseline before the alert arrives
The best answer to an unexplained flag is a reference you made yourself. On a mild day, after the house has held a steady setpoint and the system has run for at least fifteen minutes, take a few readings and keep them in one notebook or spreadsheet. Record the date, the outdoor air temperature from a shaded thermometer, the indoor setpoint, and the supply and return air temperatures at the air handler using a probe thermometer. Then clamp the condenser's running current with the clamp meter that many homeowners add to a multimeter kit, and write it next to the rated load amps on the condenser nameplate. Note whether the filter was clean that day.
Repeat the same routine monthly, and keep the conditions as close to the first set as you can. The point is consistency, not perfect numbers. When a flag shows up, pull the log and check whether your readings moved or only the tool's score did. A shift in the supply-return split with steady current points one way. A current that climbs while the split holds points another. Either way, you arrive at the service call with evidence instead of a vague alert.
Who reads the flag matters as much as the flag
ACHR News also reported on SMART Sheet Metal Workers Local Union 49, whose new training center in Lubbock is "drawing strong interest" while expanding apprenticeship opportunities for the local workforce. The Local 49 training center story is a reminder that the people who act on a diagnostic flag come out of a pipeline that takes time to build. A tool can raise a question faster than a shop can answer it.
When a company offers a predictive flag, ask who reviews it, whether a trained technician checks the unit in person, and what they will write down. Ask whether they will leave you the readings they took, not just a checkmark on the invoice. If the answer is vague, your own log becomes the only record that shows what changed and when.
Check the building before you approve the box
Many flags that look like equipment faults are really building problems. A hot attic pushes up return air temperatures, and a roof penetration or a damp corner of insulation can change how the house sheds heat. If your baseline shows the supply-return split drifting while the current holds steady, look at the attic before you accept a compressor diagnosis. Ask a roofing contractor such as Keys Roofing to check the roof and attic side of the house, and bring your log so they can see the same timeline you do.
Keep the nameplate photo, the monthly readings, the filter dates, and any alert the tool sends. A prediction can tell you where to look. Your notebook tells you whether the house agrees.
