Shai (pronounced "Shy", just in case U wanna ask for him by name) was great & did a SERIOUS job snaking my dryer vent for excess, leftover, caked-on lint. After he cleaned it out and ran the (electric) dryer, it got considerably hotter much quicker. You could definitely sense a difference.
He's very professional and friendly and I would totally recommend him to anyone. He went above and beyond even going so far as to check my other vents & mk recommendations on the cleaning of those vents and offered a recommendation for the changing of my filters, since I had just moved in to this rental (that was built in 1985).
