The company arrived 20 minutes late (9:20 am), apologized profusely and started to work, the new furnace was running at 2:55 pm. They finished up the air intake piping and cleaned up and was out the door, at 3:30 pm. They were professional and extremely neat, they left no evidence of the fact, they had even been here. We have good safe heat, the wallet is a little lighter, but there may be a $400 rebate from the gas company, which would be great.
