Performed single system cooling maintenance. The system is a comfort maker(carrier) heat pump from 2021. I investigated an air flow issue that was brought to my attention. The master bedroom is not cooling as well as the rest of the home. The system does not currently have dampers in place. Dampers would allow us to control the flow of air to more specific areas. The air handler is forming growth inside of the unit. If this is left unaddressed, the growth will get worse, stain the inside of the unit, and cause smells inside of the home. I provided pricing for a u/v stick to sterilize the inside of the unit. The capacitor on the outdoor unit is out of range per manufacture specifications. It is rated +/-6% on a 45 rating. It is currently pulling 42.2 and that is slightly under the rated reading. I provided options for a generic and upgraded capacitor. The customer mentioned excessive dust inside of the home. I presented the air scrubber audio book and pricing.
