I've got an Airco AH-130 in the house I recently bought in Edmonton, AB. The furnace tech I had do the inspection says the heat exchanger is rusting(though no apparent holes) and we should replace the furnace. Now it is old, and probably dates back to construction in 1975. But personally I'd prefer to keep this thing, as I don't trust the new high efficiency models to last more that 10 years, and with problems at that. I've asked a couple places for a quote to replace the heat exchanger, and am told that parts aren't available. What I'm wondering is if that's legitimately true, or if they just want to sell me a new furnace. Anyone able to tell me if there is a place to get parts for these things?
