Have maintenance agreement covering all work and labor. No hot water so serviceman replaced motor-found fuse also blown. Didn't have spare fuse so went to local Home Depot 2 miles away and purchased for $13. Informed me that fuse was not included in contract but never told installation of it was not included since they were already here replacing the motor, which was done AFTER installation of fuse so they weren't held up at all. Took no more than 25-30 seconds. Rec'd bill for $125 service fee for replacing $13 fuse when serviceman already here working. Never advised of this or I would have installed fuse myself! Owner a piece-of-work - refused to work with us or Atty General. Heat USA, the contract holder, was no help but informed me that owner was "crazy." Taking us to collections! DO NOT TRUST THEM! Cancelled contract. Oh, also sent 2 servicemen, one in training, and had the nerve to charge us an additional $69 service fee for 2nd man! When I questioned it, they removed that charge and said that it was a courtesy on their part! DO NOT TAKE THEIR WORD FOR ANYTHING! Get it all in writing.
