Should I fun my gas furnace fan 24/7 all year or put fan on Auto?

Depends on you if you are OK with the noise it will defentally help keep the temp more even threw out the house. It is actually harder on a fan to stop and start so leeving it run will in no way hurt it.

Let it run, but check the filter(s). They will most likely need changing more often.
