Whenever we bought this house, there was no heating system in the home at all other than an old fashioned wood burning stove, the people who lived here before us always used the wood burning stove as their main source of heating and so they never ended up installing any other heating source, however I don’t know how they did it, however they lived without another heating source for years for some reason. I believe that if it had been me, after that I would have definitely had another heating source installed during the time that I was living there. I don’t believe that I would have been able to live there for actually long without another gas furnace, but anyway, when we first moved in, we talked about maybe installing another Heating and A/C method altogether, however then we decided to wait for a little while. I wanted to save up some extra money before we started making too many changes to the house, and my spouse was okay with using an electric space heating system for a while until we were able to get another heating method for the house. It turned out to be okay for us because we didn’t have a cold winter that year. That was a good thing, too, because we didn’t save up enough money to get the new furnace put in until the next Springtime! By the time the weather started heating up, we had enough money to buy a new heating system for the house. Now, we have a great Heating and A/C unit and the indoor air levels in the home are great, however we’ve come a long way.
