I talked to the sales person and the installers about the BTU’s that the furnace would produce. They installed an 80000btu furnace. They assured me it would do the job. But we were cold this winter. The furnace never heated up the house unless it was very mild. This furnace never stopped running. My propane bill was far too high. I am not saving any money. They might as well come and remove the furnace. I am not happy.
