Our renters called them to have our hot water tank checked the tech came gave us a diagnosis and and estimate to replace it. We called them the next day to discuss the estimate & book an install and the lady who answers the phone is not able to do this (after a very long spiel about their happy today guarantee just upon answering the phone ) and has to have the GM call us back (that afternoon)... Umm ok. We wait, no call. We call again, oh he's not in he'll call us back, that afternoon, but the woman says well while I have you on the phone lets get your credit card # on file, WHAT? NO WAY I haven't agreed to anything yet let's wait till we actually get this booked at least..... Again No call.back. We ended up checking out a couple extra places and got something booked and installed (cheaper than their estimated "DEAL" ) before ACE ever called us back this time we weren't available to get the call unfortunately because I would have given them this same review. Their customer service is BRUTAL
