My furnace, due to a thermostat problem, ran continuously for over a month. The house was at about 140 degrees. Could there be any damage to the furnace from running this hot for so long?

The furnace was installed 2003. The furnace is a Ruud Achiever 90 plus. Model no.RCBA3765GG17XI serial no.TI80303923. The furnace continuously for over a month, with the house reaching approx. 135/140 degrees. This was due to a thermostat mal function.


My question could there be damage to the furnace, and air condition A coil. Should the unit be replaced?

If the furnace seems to be running fine there may be no damage, but you should still contact an HVAC professional to take a look at the unit and make sure. He or she will be able to look for unseen problems, such as a cracked heat exchanger. 

Whether or not you suspect something is wrong, in this situation having someone inspect your furnace is a good idea. If you'd like to have a contractor take a look at this, we can help you find one, here.
