Why a Gas Furnace Dries Out Your Homes Air and How to Solve It

There’s a reason why air appears drier during cold weather than in the summer. That’s since warmer air carries additional moisture, or humidity, than colder air.

The same is true within your the U.S. home. Starting your gas furnace makes your residence feel warmer but can also dry out the indoor air. Dry air can transport a whole host of ailments, including dry skin, cracked lips and make you more vulnerable to getting sick.

Here’s why your gas furnace dries out your home’s air and what you can do to combat it.

Your Furnace’s Combustion Procedures are a Portion of the Trouble

The fuel your furnace consumes isn’t the culprit responsible for making your residence’s air feel dry. Rather, it’s the way it combusts.

There are two different types of gas furnaces, standard and high efficiency. With an older standard furnace, you can see light from the burners when it’s running. A newer, high-efficiency furnace is tightly sealed.

A standard furnace, also termed an atmosphere furnace, pulls air from inside your home to function. Because the furnace continuously uses air to burn, it will also draw in cold, dry air from outdoors, which in turn lowers your residence’s humidity.

High-efficiency furnaces, also referred to as a sealed combustion furnace, are used for keeping your humidity steady. They draw all their combustion air from your home’s exterior, but it stays locked in the sealed furnace. As an extra perk, they keep your house more cozy while requiring less energy. Switching to an ENERGY STAR® furnace from an old furnace could save you as much as 40% on heating costs, according to Lennox®.

In addition to combustion, cold air also naturally seeps into your home during the winter. Lower humidity means the air will snatch moisture quickly from your skin, lips, nose and throat. It also contributes to static electricity.

How to Even Out Humidity in Your Home

Using a humidifier. While a portable humidifier can only make one room comfy at a time, a whole-house humidifier will transport that comfort across your house.

These are just a few humidifier benefits you’ll receive when you install a whole-home system.

Enhanced Health During Cold and Flu Season

It’s no surprise cold weather is the worst time for colds, flu and other sicknesses. That’s due to the fact you’re more susceptible to become sick when your nose and throat are dry. Under certain airflow conditions, air at the right humidity level may also restrict the spread of some viruses. In addition, it can reduce year-round allergy symptoms.

Soothes Dry Skin

If you have constantly dry skin or eczema, you know just how irritating those conditions can be during winter. Installing a whole-house humidifier will help your skin keep more moisture.

Better Sleep

Preserving your bedroom at the preferred temperature and humidity level will keep you comfortable at night. It can also alleviate loud snoring, since your throat and nose will be better hydrated.

Guards the Wood in Your Home

Cabinets, flooring, furniture and basically anything in your home that’s wood is affected when humidity is too low. This is due to the fact dry air moves moisture from the wood and causes it to split. Having your house’s humidity at the correct level will keep your home’s furnishings looking their best.

Little Maintenance Needed

Between steady filter changes and continual refilling, portable humidifiers rely on a lot of upkeep. A whole-house humidifier only needs servicing about once a year, which can be completed along with your furnace tune-up.

A steam humidifier has the smallest amount of maintenance since it doesn’t require a pad. It holds water in a canister and boils it into steam that gets moved through your ductwork. Because it’s independently powered, it can run when the furnace isn’t running.
