Zach was very friendly despite the after hours call and the furnace being located outside. It didn't take him long to concur with my suspicion of a faulty motor which was replaced 4 years ago. He called the next morning to let me know when he'd arrive and it didn't take him long to replace the motor. The initial callback was less than 2 minutes after I talked to their answering service. Excellent experience despite our disappointment with the short life of the previous motor. Thanks!
