Upon arrival, I found that majority of the grills are covered in a growth. Home owner was on site during this visit. I removed 2 grills and found that the supply boots are not sealed. Also, I found that the home has high humidity. I told the customer, we need these units to run for longer periods of time and to leave the fan on auto. I measured all of the grills (review pictures for sizes), and I discussed sealing the supply boots during grill replacement. The estimate that will be provided will include sealing the supply boots. I noticed that the downstairs thermostat may be getting teased by the living room supply vent, also. All of the vents are 3 way vents.
