When our unit was New,1st trip out the A/C blew Oil out and over the roof.Called our dealer,he called F/R,F/R called us and told where the nearest F/R repair was.We called and took the unit to them,returned in (10) days and picked up the unit.They replaced the entire A/C unit. Like always the Battery was Dead,they never seem to remember to disconnect the Battery! Youroo!!
