Well, that's good news. I was hoping the furnace was more of a problem rather than the fridge... I think my husband disconnected the CO2 detector, which makes me a bit nervous.
I am using a deep cycle battery, but I keep seeing posts about two 6V batteries run in series being a better option. I wish I didn't just buy a brand new 12V!
