Came out for a prepaid msc ac tune up. Found the ac is a 2004 carrier. Found the fan motor has signs of oil. Found contactor has burning on it. I also found the blower need to be cleaned. Gave options for all of these repairs today. Options were declined. Found our temp split is a little higher due to not having a heat load on home. Found no other issues with ac today. System was working properly when I left the call.
