Today I had the pleasure of conducting maintenance on a 12 year old Amana systems. Upon arrival, the homeowner stated that they had just replaced the filter but haven’t turned on the ac yet this season. I started by verifying system cleanliness and found the blower assembly and ducts dirty and in need of cleaning. I then verified all amps temps and pressures. I found the system operating within manufacturer specifications. I discussed my findings with the homeowner who would like to discuss with her husband. All conditions otherwise normal at this time.
