I know them as Dryer Vent Pros, but Champion Appliance Care did a fabulous job for me. Absolutely fabulous! My dryer vent hadn't been cleaned for at least twenty years. When I bought a new washer and dryer, the new dryer didn't work quite right. My husband thought it was just a sub-standard new appliance, but I thought it might be the dryer vent. So I called Champion and he came out and brought along his college son, home during the holidays. My dryer vent stretches halfway across the basement and it took some ingenuity on their part to get the whole thing cleared, but they did it. I'd recommend Champion Appliance Care to anyone! They did a great job and now my new dryer works just like...well, new! Five stars for a great job and a great company.
