What is that switch above my thermostat?

Well the forecast for later on this week is going to be a bit frightful and as the temperature drops a bit lower and your home will feel that temperature change and may act a bit different. Here are a few TIPS to help you , and to help your home…
Lets first address the switch by your thermostat that is labelled “ventilation switch”. The switch to activate the ventilation fan is in the hallway, near your furnace thermostat. This fan is wired to your furnace fan, so when the switch is turned on, it activates your furnace to circulate air which then brings fresh air into your home through your fresh air intake (a duct from the outside that goes directly into your ductwork). When activated it will also turn one bathroom fan on in your home, and that in most cases is the bathroom fan closest to the switch, this fan is now used to pull the air out of your home . When this system is running, it could feel like your furnace is blowing cold air – this is normal.
So why is this important? When temperatures drop and you are nestled nicely in you’re home the internal & external temperatures will vary greatly which may cause moisture to form on the base of your windows, if left unchecked it could turn into ice, and as it warms up it will melt and could do damage to your walls or window casings. So use this switch when cooking, if you are doing any entertaining, or just to give your home a treat and circulate some important fresh air into your home.
Second – if you have window coverings (blinds) remember it is very important to have those window coverings up at least one inch from the bottom, the warm air against the glass will help prevent moisture from accumulating against the glass window during these colder nights.
Remember the window glass will become the coldest point in your home.
