I arrived at our client home for a heat maintenance inspection. Our clients filter had recently been replaced and did not need to be changed today. I began at the outdoor unit by checking and testing the electrical components. Everything passed.i spoke to our client regarding a surge protector for her equipment and will send her information to look at. I proceeded inside and tested the electric strip heat and blower motor to ensure everything was running properly. The blower motor fan has early signs of dust accumulated on it and I spoke to our client briefly regarding air purification. Everything passed inspection today and unit is running properly on departure.
