Polar Vortex Signals Early Winter
Winter got off to an early start this year. Much of the nation has seen temperatures plunge as frigid arctic air dips south. Early predictions by AccuWeather suggest the polar vortex will provide multiple blasts of cold air this winter. The one bit of good news is that the mass of arctic air should march in and then retreat, as opposed to lingering for several months.
However, in mid-November record lows were shattered across the country and nearly 50 percent of the contiguous U.S. was covered in snow – the highest percentage since NOAA began tracking the figure, according to The Weather Channel.
Protecting Loved Ones from the polar vortex
While the polar vortex will make heading outside a miserable experience, it will make sitting inside less fun too. Families should prepare now for what will be another long winter. Homeowners who have not had their furnace system checked and cleaned need to do so. Also consider how you will deal with low humidity levels. Humidity refers to the amount of moisture that is in the air. As the relative humidity (RH) drops, the air begins to pull moisture out of anything that it can – including people.
When cold outdoor air is brought into the home and heated, indoor relative humidity drops significantly. Because the furnace runs non-stop during a polar vortex, homes get very dry. Dry air causes a host of health and comfort issues, including:
- Itchy, dry eyes
- Cracked and itchy skin
- Static shocks
- Dry, itchy noses
- Sore throat
Don’t Hang Your House Out To Dry
Humidity control is also integral to protecting a house and keeping heating bills down. Adding humidity when heating allows people to feel comfortable at lower temperatures. Energy.gov states that turning a thermostat back 10 – 15 degrees for eight hours can reduce heating bills by 5 – 15 percent a year. During a polar vortex, keeping the thermostat down a few degrees could quickly add up to big savings.
Just like people, a house also “feels” the pressures of a polar vortex. Dry air can cause expensive electronic devices to fail, create cracks in wood floors and damage instruments and furniture. Ensuring that dry air doesn’t suck the life out of a house requires adding moisture throughout the heating season. A family’s daily routines, such as cooking, bathing and doing laundry add some moisture to the home each day – but not enough to maintain optimal levels.
How to Control the Humidity in Your Home
Humidifiers are designed to efficiently and effectively control indoor RH during the winter months. Some people sleep with a small humidifier by their bed to prevent a dry throat in the morning, or purchase larger units to raise the RH in an entire room.
Many homeowners can also benefit from whole-house humidification solutions. A whole-home humidifier adds moisture to every room by using the duct system of the furnace. Installed by an HVAC contractor, whole-house humidification products can also automatically change the amount of moisture being added depending on variables such as indoor and outdoor temperature. By continually monitoring and controlling how much humidity is added, automatic humidifiers raise RH without causing condensation to form on windows or walls.
