The eternal furnace
Posted: Sun Jan 15, 2012 1:58 pm
We have a high efficiency forced air gas furnace. I have it regularly maintained.
With the current cold snap, the furnace has been running constantly during the day, yet the temperature never gets above 68 or 69 (its programmed for 70 during the day; it stops at night when it is programmed for 63).
This isn't the first time we have had cold weather, but it is the first time the furnace has exhibited this behaviour. Naturally, this happens on a holiday weekend when service is at a premium. There doesn't appear to be anything wrong with the furnace; I thought perhaps the filter we blocked, but the behaviour continued even with the filter removed.
I'm starting to wonder whether the gas company is adulterating the gas?
