Bird Nest in vent pipe

Dear FIT
Q.I tried to turn on my gas furnace yesterday for the first time this season, and the hot surface igniter did not ignite, even though it looks fine. I checked the pressure switch, and it read 26 volts at one terminal and 0 volts at the other. I pulled the tube from the leading pressure switch that comes from the draft inducer and felt no suction with the inducer running. I got an "error code 31."

This morning I checked the vents, which are located on the house sidewall, and I found bird nesting material packed in one of the vents. The vent makes a 90 degree turn. Any tips for cleaning nesting material from the vent? Is the pressure switch remaining in the wrong position because the nesting material is restricting air flow?

High Wind

Hello FIT,
Q: I am having problems with the intake vent of my new furnace, it is a PVC inlet. When high winds come along it will make the furnace cycle on and off. Right now I have a 90 degree elbow on the end of the intake pipe pointing down. Will the e-cap prevent this from happening?
Thanks, Tim

I can't find my AC Filter

Dear FIT,

I just recently bought a 2300sf home and the heating a cooling unit was replaced less than two years prior to my purchase. I know this sounds strange, but for the life of me, I cannot figure out where the filter to my furnace is. I know it needs changed. The unit runs constantly. My gas bill is sky high and hardly any air is blowing out of my floor vents. The house I just sold, the filters were in the hallway, two of them, but not the case here. I have also looked right above the unit in the garage, but no filter to be found. The unit is a Lennox high-efficiency. I am stressed out. I need help.
