Furnace and AC running at same time.
Hi guys. Bought a Montana 2016 3791RD in May, it was used with very little use. Question is tried the furnace for the first time to check it,s operation for the up coming cold, ill be using it only for the month of October or so. When furnace kicked on so did the AC in the living area but it didn't feel like it was cold air coming out maybe just the fan. Any suggestions on what's happening and how to resolve this issue. Thanks, Chuck.
