Called the company in the morning after realizing the AC had gone out and by 11:30 that morning AC was working again. Very impressed, so we will have them come back for routine maintenance.

We were referred by a friend to call Relentless and thank goodness for them! They were honest and upfront and even let us know our system was probably still under warranty, which it was.
