When Changing The Filter, Which Way Should The Arrow Point?
The arrow is always pointing the direction of air flow and should always point toward the furnace. This is the air returning from your house carrying dust and other potential allergens. The filter is used to keep these from getting into the furnace and also to clean the air you breathe. Inexpensive filters mainly help to protect the blower from dust, and the more expensive ones can help you control particles that could be harmful for your health.

Should I Have The Fan Switch On “Auto” Or “On”?
That is a good question and the primary answer is dependent on your preference. The high efficiency systems have a blower motor designed to be running all the time to filter the air in the home and mix the air to even out hot/cold spots in the home. We recommend leaving the fan switch on “ON” all year but especially in the summer months since it is more efficient for your air conditioner.
How Low Should I Set My Thermostat While Away on a Winter Vacation?
Typically our customers set their thermostats at 60-65° F. You should keep the thermostat set high enough so that the basement is well above freezing. Pipes are in the basement, so keeping a warm temperature will help prevent pipes from freezing, then bursting. To be safe, you should expect the basement to be about 10 degrees lower than the main level. You should also consider the location of your refrigerator. According to the Association of Home Appliance Manufacturers, refrigerators and freezers with automatic defrost systems (most current models) are sensitive to the surrounding air temperature. Temperatures below 60 degrees can affect the amount of time the compressor runs, thereby affecting your food. If you are considering setting your home temperature below 60 degrees, check the refrigerator/freezer manufacturer’s use and care manual, to make sure you maintain a temperature that will keep your food from spoiling. Also consider having someone check on your house while you are away. If they are only checking once a week, you may want to set the thermostat higher than if they are checking twice a week.
How Much Humidity Should I Have In My Home During The Winter?
This varies according to the outside temperature. The average humidity level is about 35%. When it is really cold, your windows may have condensation or frost build up on them so the automatic humidistats will bring that number down to prevent that from happening.
Aprilaire has a chart based on the outside temperature showing what the humidity level should be:
