12/5/25 Dan I arrived to the customers home for a QA on a dehumidifier. Joe was here as well with me . We found there was a whistling sound type of acoustic sound coming from the first floor returns. We are recommending to replace the 10 inch metal run out from the dehumidifier to the return and replace it with 10 inch flex . This should help dampen down the sound through the returns. I also replaced a thermostat on the first floor for their daughter’s room to an ecobee Wi-Fi thermostat . The customer wanted to be able to operate the thermostat without bothering her daughter in her bedroom when she’s sleeping. I collected $446.25 for the new thermostat installation, paid by cc. The dehumidifier looks good just some noise from the 10” round metal pipe.
