In Jan 2011 our old dinosaur of a furnace (circa 1950) finally gave up the ghost. This happened during the coldest part and week of the year. We called a furnace repair shop and they told us it would be cheaper to just replace it with a new one than to find the parts would cost (if they could even find them) for our old furnace. So, we went ahead and replaced our old furnace with what the furnace company had in stock, which was a Gibson Furnace. The only thing that wasnt replaced was the thermostat on the wall. (which is also quite old) Anyway, we just are not happy with the heat produced by this new furnace. The blower works fine and more air comes out of the vents than ever before with the old furnace, however, its just not keeping the house as warm as the old furnace, even with the thermostat turned wayyy up. I checked the size of the furnace against the size of the house and it supposedly is to be the correct size, so I just dont know what else to do other than replace the furnace yet again, with another furnace, that sure wont be a Gibson Furnace. Im toying with the idea of replacing the thermostat before I go ahead and replace the furnace again, but im not really sure that would help. Any suggestions would be great!
