This what I follow and it works for me only a recommendation One common question we get asked by all you snow birds and winter vacationers is what temperature should your thermostat be set to while you’re away? Our expert service technicians strongly recommend you do not set your thermostat below 60 degrees. By placing your thermostat settings below 60 degrees, it causes the furnace to cycle for shorter periods of time, not allowing the condensate to escape the exhaust pipe, causing ice build-up. When the ice build-up occurs, it won’t allow your furnace to run causing a “no heat” situation which can result in some pretty costly repairs to not only your furnace, but if the house gets cold enough, it could cause your pipes to burst.
