Why Your Gas Furnace Develops Dry Air in Your Home and How to Solve It

There’s a reason why air feels drier in the winter than when it’s hotter. That’s because warmer air retains more moisture, or humidity, than colder air.

The same is true inside your Hurricane home. Starting your gas furnace makes your home feel warmer but can also dry out the indoor air. Dry air can carry a whole host of ailments, including dry skin, cracked lips and make you more susceptible to getting sick.

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

Your Furnace’s Combustion Steps are a share the Problem

The fuel your furnace needs isn’t the source responsible for making your house’s air appear dry. Rather, it’s the combustion process.

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

A standard furnace, also called an atmosphere furnace, pulls air from inside your home to combust. Because the furnace constantly requires air to burn, it will also pull cold, dry air from outdoors, which in turn lowers your house’s humidity.

High-efficiency furnaces, also referred to as a sealed combustion furnace, are best for keeping your humidity balanced. They pull all their combustion air from your home’s exterior, but it stays trapped in the sealed furnace. As an extra advantage, they keep your house more comfortable while consuming less energy. Switching to an ENERGY STAR® furnace from an old furnace might save you as much as 40% on heating costs, according to Lennox®.

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

How to Stabilize 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 spread that comfort across your home.

These are just a few humidifier benefits you’ll get when you upgrade to a whole-home system.

Enhanced Health During Cold and Flu Season

It’s typical that cooler weather is the worst time for colds, flu and other sicknesses. That’s because you’re more apt to get sick when your nose and throat are dry. Under particular airflow conditions, air at the correct humidity level might also restrict the spread of some viruses. In addition, it can weaken year-round allergy symptoms.

Eases Dry Skin

If you have consistent dry skin or eczema, you recognize just how irritating those conditions can be during winter. Adding a whole-house humidifier will help your skin hold onto more moisture.

Improved Sleep

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

Protects the Wood in Your Residence

Cabinets, flooring, furniture and generally anything in your house that’s wood is affected when humidity is too low. This is a result of the fact dry air pulls moisture from the wood and causes it to split. Having your residence’s humidity at the right level will keep your home’s furnishings looking their best.

Little Maintenance Needed

Between regular filter changes and continuous refilling, portable humidifiers require a lot of upkeep. A whole-house humidifier only needs maintenance about once a year, which can be completed along with your furnace tune-up.

A steam humidifier has the lowest amount of maintenance since it doesn’t need a pad. It stores water in a canister and boils it into steam that gets transported through your ductwork. Because it’s independently powered, it can run when the furnace is off.
