had a repair on furnace from my gas provider after he fixed part he said my ducts are lined wrong or as he said "insuffucient" the duct from the water heater because it so tall and my basement is so low runs tilting down slightly then almost straight into main duct. he said it needs to go from down to up.
from the furnace the duct goes up slightly and then slightly dip down(i probably could pull it up) and then is about parrell as the water hear into the wall or main duct(cannot remember)
how much of this is all true and he also said the ducts need to be strapped, none are strapped. he threatened to shut the furnance off immediately but then said i give u 30 days. i have had main of there tech's in plus others(all licensed) guys for tune ups, repairs etc and plus they installed the water heater as i rent it, never a word of this, plus on x-mass eve i a sensor issue, frunance fired on off repeatly so i called in told them i smelt gas guy comes says all if fine, i cleaned the sensor starts working no problem. so why wouldn't that emergency guy tell me i may have gas build up in my "insufficient" ducts then. so confused.
