noise in furnace/ hi and low
We have noticed that after we run our heat, there is a fairly low but audible sound coming from the area below our kitchen counter (we have a 3400RL) as if steam is escaping. Does anybody know if this is considered normal? Also, we can only run one speed, apparently high, for heat. There is a high/low switch but it only affects the ac. Anyone chime in on that?
