2 guys came in and made a mess of our house. Tells me on the phone is $99 for the duct cleaning than comes after telling me that it only includes the air ducts not the furnace or the air return.. than tells me it an additional $300. Why would I only want the main ducts without the return or the furnace.. and after I agreed to the ridiculous amount. I was sitting in my living room and all kinds of dust and lint started blowing all over my house and they didn't even clean up after there mess. They shouldnt be allowed to do business at all.. please don't use them ever.
