Contacted homeowner, she asked us to park in the back alley by the garage. Client met us at the garage door. She showed us the dirty supply grill. Upon further investigation we noticed there was not any dampers to balance the airflow to that supply. We provided the client with our findings and provided estimate to reconstruct the duct run and new supply grill. Supply grill is 16”x8” (3 way). Preformed cooling maintenance checked all electrical components inside and outside. All tested within manufacturer specifications. We treated the drain line with total c and rinsed the out door coils. Unit was cooling upon departure.
