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.

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.
