Preformed dryer vent cleaning presented before and after photos of work completed. Preformed single system heat maintenance on a 2022 gas. I tested all electrical and safeties. All tested within manufacturer specifications. I noticed the blower wheel to have some dust build up on it which can cause the motor to fail prematurely. The client did not need the filter changed at this time. I proceeded to the outside unit to visually inspect and I notice the unit does not have surge protection on it. I provided estimates for installing a surge protector and blower wheel cleaning. Unit was cooling upon departure.
