Arrived to system off, turned system in cool and checked refrigerant pressures found system is low 1-2lbs of R410A, indoor blower and coils are dirty, return duct has a restriction, condensate safety is not wired in, outdoor coils are dirty. If homeowner opted for leak searching and replacing indoor coil there is a possibility that this coil is out of stock due to the change in refrigerants. Spoke with Jerry he decided to have a comfort advisor come out and give quote on upgrading comfort system. System is 5 years old, checked warranty through weather king (brand) and found that system does not have a warranty. Recommend leaving system off to prevent indoor coils from freezing. OD temp 78
