Don't know how many people remember how much it cost to change a light bulb a few months back, 150.oo when you call the electric company. well i called the same one again yesterday cuase i knew my heater was louder and sounded like it was grinding, no one said they thought anything was strange or grinding. well i was feeling very sick and dizzy yesterday and i didn't hear it blowing in the room i was in. very weak blowing. so i took smokey pattys to stay the night and went to get a carbon monoxide reader. it has been at zero so i then new it was just me not feeling well. they came out today and he said it sounded like it was grinding also. he took the cover off outside and there were 2 LEAVES being pulled against the motor. 88dollars to take 2 leaves out. that company is going to love me calling them cuase it is always for nothing. the light bulb if you dont know is after an electrical storm my fuse tripped and i couldn't get it on and klye couldn;'t get it on so i called them and after a while they changed the lightbulb and the fuse tripped back on. this was a new technology they year my house was built it is a saftey device. i will put the leaves on my surprising home owner experience. love you all take care 11-29-07
