Lint buildup can develop slowly enough that many homeowners do not realise the dryer is working harder than it should. I noticed this when our appliance started needing two full cycles to dry towels and the laundry room felt unusually warm after every load. At first, I thought the dryer itself was wearing out, but the issue turned out to be a restricted vent. To resolve it, I booked a cleaning through https://dryerventcleaningtoday.ca/dryer-vent-cleaning-in-markham/ so the entire duct could be inspected and cleared professionally. The technician removed a surprisingly dense accumulation of lint from the vent line. After the service, drying times improved right away and the dryer no longer seemed to overheat. Since then, having the vent cleaned about once a year has helped keep the appliance running more efficiently and with fewer safety concerns.
