Summer is the worst season for me because the ambient humidity is high, and the air conditioner cools the frog room too much. Even with all the basement vents closed, it's 10 degrees cooler down there. Before I covered the main HVAC stack with insulation, the frog room was getting down to 64° F in the middle of summer. Now it's only 68.
I don't need household heat or AC in the spring and fall, but I run a space heater for the frog room. I refuse to run a space heater AND central air in the summer.
Winter is my favorite. Furnace keeps the frog room warm and the air is dry enough that I don't need to worry about active ventilation for the vivs.
I should also note: I turn down my misting in the summer on account of the humidity.
My experience has been similar. My frog room is in my basement and I do similar things with humidity in my frog room.
My AC actually keeps my frog room at a perfect temperature in the summer. 73F in the vivariums with the lights on. The furnace in the winter also keeps the temperatures around the same. September and October aren't great times, too warm for the great to turn on and not hot enough for the AC to come on. Leaves it a bit warmer than I prefer in the frog room.
