This dryer had an accordon vent connecting the dryer to the wall. At 16.3 miles per hour, this is the point where you will notice dryer preformance issues. This vent didn’t show a lot of lint at the top of the vent indicating that the lint is not making it to the top of the vent. It had also been over 5 years since the vent was last cleaned.
Because the air velocity is above 20 miles per hour and it had been several years since it needed servicing, we educated the client about the situation but did not make a reccomendation. We suggested calling us back in 4 years to take follow-up measurements and reassess the situation.
