Upon arrival customer stated they had whole home remodel and there was a lot of construction dust from it. Wanted to have hvac system inspected to see if it needed cleaning. Looked at system blower wheel was dirty, inside return plenum was dirty, duct system runs were dirty, system filter was very clogged and dirty. Overall equipment was in good shape. Recommended duct cleaning, cleaning blower wheel and inside furnace, advanced Uv light /air purifier and iwave ionizer. Customer approved to have media filter replaced today, duct cleaning and blower wheel cleaned. Will have duct system cleaned first and then blower wheel. System is working in both heating and cooling with no issues at this time.
