A thermal camera can "see" HVAC air flow - you and I can't!
This was an inspection of a new property, prior to the buyer's final walk through.
Months ago I did the pre-drywall inspection.
A final walk through inspection typically follows that, and comes near to the settlement but with enough time to get any inspected things done prior to settlement.
One important thing is to determine if the HVAC system is blowing sufficient air through each register.
That can be done by hand, feeling the air flow. If it feels weak I have an anemometer to measure the air flow. But, if it feels good I move on to the next register.
The day was raining and about 55F. So the heat was tested. How was it working?
This register is in the kitchen eating space, beside the end of a long counter top and cabinets.
How hard is the air blowing? Very well! You can see the air pattern extend all the way to the ceiling!
That little red dot in the upper left is the security system motion sensor, which always carries a small electric charge and therefore is slightly warm.
When I am doing a Mighty Mo sweep of the house I can investigate the HVAC registers in this way, in addition to the feel test!
My recommendation: even though a house is brand new, never discount the idea that it should be inspected. This house had a number of things questioned or pointed out on the inspection report. So when my client walks through with the supervisor he will have a list from my report to discuss or add to the supervisor's final walk through list of things to be done. And when a thermal camera finds insulation issues, as it did here, it never hurts! Thermal images of poorly-insulated spots are definitive!
