Summers And Smith Cooling & Heating Ltd

Summers and Smith have serviced our church furnaces for several years. When we requested one furnace be rewired so that the fan would run continuously to improve ventilation service techs came and were unable to complete the work. Suddenly we are advised we need to replace both furnaces. One furnace has been tagged as not meeting manufacturers specifications. It was installed by licensed professionals and serviced for several years by Summers and Smith themselves and suddenly it's unsafe??? I am disgusted.
