I just moved into a new house where the gas furnace and water heater are located in an unfinished dirt basement. I just noticed my gas furnace sounds as if a 747 was landing in my living room when it turns on. I called the gas company guy and he said the equipment is fine but because this house didn't have a chimney a motor was installed on the furnace to vent the (fumes, air?) out of the house and the motor is noisy. Plus he thought the two plastic pipes doing the venting were vibrating against the plywood encasement. He suggested insulating my floors and moving the pipes a bit. Has anybody had a similar experience? Is there an alternative way to vent one of these beasts? Do these things really have to be so noisy or do I have a cheap motor. Who else might I ring to solve this problem. My other house didn't have insulated floors and it was pretty quiet. Of course those were wooden floors and this house has pergo. Any advice--especially who to call would be great.
