I live in the southeast, and truth be told, I spend way more currency on my air conditioner than I do on my heating. Even so, I do understand the fact that millions of people are looking for ways to save currency once it is time to turn the furnace on. In my neck of the woods, everyone has electric heating systems that are part of the central heating and cooling system. All that is involved for people around here is to simply change the switch on their control unit, and moving the control unit switch from cooling to heating is absolutely all the people have to do once freezing weather arrives. Other people have much more efficient types of furnaces and often the air conditioner and the heating are not a part of one central HVAC unit. Although these types of furnaces are generally more efficient than central heating, because of the severe freezing and the long time that winter time is upon us, we are all still looking for ways to save cash when it comes to the heating bill each winter. The first thing you should do is seal any leaks you might have. Get some caulking and just go around the windows and the doors. This will help keep the freezing air out and your gas furnace will not have to work as hard. Another thing you should do is let there be light. Open your curtains and let the sunlight shine naturally like a gas furnace so that your air is already as heated as it can be when the gas furnace engages. The third thing you should do is try to wear comfy warm clothes even around the condo and put an extra blanket on the bed. This may seem obvious, however lots of folks prefer to walk around in shorts or just a t-shirt, which is just putting extra pressure on your gas furnace.
