I called upon Sears Duct Cleaning of Memphis to come clean out our clogged dryer vent in November of 2016.
They came out while my wife was home, and could not locate the vent exit on the exterior of our house (it is on the roof).
So, they stuck a vacuum into the wall at the dryer end of the vent, fiddled around for a few minutes, and called it a day.
Lo and behold, my dryer is still overheating, and still has the "Vent Sensor" warning flashing.
Frustrated, I had a friend come over with a ladder and we checked the roof end of the vent. It was packed completely full of dust and lint still. It had not been cleaned AT ALL.
I inquired about a refund, waited weeks for a response, only to discover that Sears Services "guarantee" is null and void if any subsequent cleaning has been performed. They honestly expected us to not dry any clothes for weeks while we waited for them to get around to returning our call.
I am out $150. Consumer beware of these lazy con artists.
