Membership is due for renewal. Customer is selling the home. Customer was concerned about a loud noise from the outdoor unit. Unit was sounding normal. Checked all electrical components, Freon levels, and delta t. Cleared and flushed the drain line. System is working well and within normal range. Summary: customer mentioned small gap in supply. We can use a foam spray to seal the top of the supply duct. I suggest a UVC germicidal unit for inside the cabinet to help keep it clean and improve indoor air quality. I collected signatures and payment. This job has been completed. Thank you for choosing Total Air!
