Who Would I Call For Creature In Furnace or Flu?

[GeoGeo]

Sometimes when I go into my garage I hear something making a noise either in my furnace or in the flu pipe. I am hoping it is just an anole. The sound stops before I can get to the unit to see if I can figure out where it is coming from. But it is definitely a creature and not a normal sound. Been going on for about a week. Worried it might be a bird building a nest in the flu pipe. Who do you call to check on something like this?

It maybe a frog. We just had one removed when the service tech came out for the annual clean out

I'd start with a phone call to Chuck Farrell.. if it is something he doesn't deal with he ma be able to suggest. Good luck
