Preformed dryer vent cleaning, presented before and after photos to client. Preformed two system heating maintenance on 2019 Goodman furnaces. I tested all electrical components and safeties inside the units. All electrical and safeties tested within manufacturer specifications. I inspected the duct work and blower wheels of each unit for over all cleanliness. I found both systems could benefit from having a the ducts and plenum boxes cleaned along with both blower wheels. Temperature being supplied to the home for the downstairs unit was 115 and 72 return and the upstairs was 117 and 70 return. Both units were cooling upon departure.
