After two service on my central a/c service tech determined that the leaks in my 12 year old unit could not be repaired. sales Mgr. Bob Shamy came to my house and wrote a proposal for a replacement unit.. Installation date was agreed on and the service techs arrived on time. They put drop cloths on the carpet where they had to walk. Their work was done in a timely and efficient manner. I would recommend the Lennox unit and Wojo's to anyone .
