Dealing With the Cold: HVAC Tips

Let your ceiling fan help heat your home. When looking up at the ceiling fan, it should rotate clockwise in order to move warm air downward.

It is common for a heat pump to freeze over with a thin layer of frost this time of year. Normally, it will be taken care of by the unit’s built-in defrost cycle. However, if the pump is covered in ice inside and out, this is a problem that will prevent it from running efficiently.

Tarps are valuable in protecting a lot of items that stay out in the cold. Your HVAC outdoor unit is not one of them though! A tarp can cause condensation which will damage the unit. If you are worried about large amounts of snow covering the top of the unit, you can however use a vented cover or even a piece of plywood.

If a furnace is your primary source of indoor heat, generally most of the unit is also indoors but you still have a condensation drain line that can freeze in extreme temperatures. If the line freezes, the furnace will not work properly until it is thawed.

Even when it is extremely cold outside, the sun provides natural heat on a clear day. If you have windows facing south, open your curtains during the day to allow sunlight to enter your home.

Your HVAC unit should have a built-in safety feature called a freeze stat. A freeze stat, also referred to as a low temperature cutout, keeps the HVAC unit’s coils from freezing by monitoring the temperature of air flowing across the coils. If the coils are receiving too much cold air, the freeze stat will shut down the system to prevent freezing.

A clean filter will always help heat your home better and improve the indoor air quality as well.

If your HVAC unit is located on top of your building, make sure your drainage system flows away from the unit and not into the indoor ceiling. Ice and snow can still melt on a cold day and can provide an excess of unwanted water.

Take a look at your doors and windows to make sure heat isn’t leaving and unwanted cold air is coming in. A common occurrence area is the gap between the bottom of the door and the floor. While you are investigating the windows, make sure there isn’t extra moisture on the inside.

If you are using a space heater to help get by in the cold winter, make sure the heater is clear of any combustible or flammable items.
