Advanced Furnace came to clean the vents in my home. I went with them even though the price they quoted to me was higher than another company I found in a mailer. They were very professional on the phone and it sounded like they had a lot of experience. They came to my house with a big red truck that looked like it could have sucked in my whole house. I was very impressed with the equipment. The job was done more quickly than I expected but everything looks and smells much cleaner. I would recommend them to my friends.
