When I needed help with ventilation, I didn't think twice and called a company that specializes in dryer vent cleaning Richmond Hill, and they did a fantastic job. They inspected the entire vent, removed a huge amount of lint, and even gave me tips on ongoing maintenance. It really made a difference to drying times and energy efficiency. If you live in this area, be sure to look for companies that advertise local expertise—they often know the ins and outs of older homes' venting systems.
