I HAD A PROBLEM WITH MY OILFURNACE THAT WAS IN STALLED BY RM THORNTON IN MARCH OF 2015 WHEN I CALLED IN DECEMBER IWAS TOLD THAT THER WOULD BE A SERVICE CHARGE JUST TO LOOK AT IT AND WAS ALSO TOLD IF THIS WAS A LACK OF MAINTENANCE ISSUE I WOULD BE CHARGED FOR THE COMPLETE REPAIR. REALLY!!!!!!!!!!!!!!!!! YOU MEAN TO TELL ME THAT I SHOULD BE MAINTAINING THIS UNIT WITH LES THEN 20 HRS. OF OPERATION??????? I OWN A SERVICE STATION AND WHEN A CUSTOMER CALLS ME AFTER A REPAIR OF ANY KIND THAT WEVE DONE WITH AN ISSUE I WILL TELL THEM BRING IT IN AND THER WILL BE N/C FOR CHECK OUT OF SAID PROBLEMS THEN WE GO FROM THERE I FIND IT VERY HARD TO BELIEVE THAT THIS IS EVAN CLOSE TO ADDI QUITE CUSTOMER SERVICE..GOOD LUCK. BUT TO BE FAIR THE TECHS INSTALLING THE FURNACE WERE GREAT
