thankfully i didn't have to call someone to our house to get it fixed, our furnace unit is a Carrier, and they made the switchout process relatively painfree, and thankfully there was a retail store around that actually carried the part that i needed. Funny enough, the furnace acted up again this winter, but thankfully all i needed to do was cut the power for a while to reset it, and now is back up and running - whew!
