We just knocked a wall out of our house and a heat duct was exposed and my dog was walking by and dropped the ball and it dropped in the duct and rolled down i'm guessing towards the heater. Is that a fire hazard?
If it goes all the way to the heat exchanger it could melt and catch fire .If it stopped in a bend or some where it can't go any further is should be ok but , I would call a service man unless you can be sure its not at the exchange
If you have A.C. then you have nothing to worry about. Your A.C. coil is above the furnace, and the ball would just get stuck there. Now if it fell down the return air, or cold air exchange, then next time you change your furnace filter, you would find it, that or else it is stuck someplace in the pipes. YOU should have nothing to worry about, unless your system is completely abnormal.
Send the dog down after it..... But like other commenter said.. depends on how far it made it... it will probally just smell like burnt nylon for a while and stink the house up
