Hello I'm looking for an oil furnace in a couple of years and I'm not sure what to buy. I like oil so maybe a hi-efficent to try, my last furnace was a mid oil. I thought about looking at direct vent thats the one that has a cold air vented out isn't it. I put a stainless liner but my chimney
needs to be repaired. I heard that with direct vent that there is no where to clean them.
