Choate's Air Conditioning, Heating, & Plumbing cleaned out all 15 duct work units and resealed the joints in the attic for I was loosing a lot of air. The prices for this service didn't hurt me - so I think their prices are good. Real good. They sent out two workers who were courteous, on time - and in fact they arrived a couple of hours before their scheduled time, so instead of showing up at noon, they arrived at 9AM! I really appreciated this. Mr. Linn is a very good person, very professional and enjoyable to have around.
