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

There’s a reason why air appears drier during cold weather than when it’s hotter. That’s because warmer air retains extra moisture, or humidity, than colder air.

The same is true inside your Alliance house. Using 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, such as dry skin, cracked lips and make you more exposed to getting sick.

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

Your Furnace’s Combustion Procedures are a share the Trouble

The fuel your furnace uses isn’t the source responsible for making your home’s air feel dry. Rather, it’s the combustion process.

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

A standard furnace, also termed an atmosphere furnace, takes air from inside your home to function. Because the furnace consistently needs air to burn, it will also draw in cold, dry air from outdoors, which in turn affects your home’s humidity.

High-efficiency furnaces, also known as a sealed combustion furnace, are best for keeping your humidity even. They draw all their combustion air from outdoors, but it stays contained in the sealed furnace. As an added perk, they keep your house more cozy while needing less energy. Moving to an ENERGY STAR® furnace from an old furnace can save you as much as 40% on heating costs, according to Lennox®.

Other than combustion, cold air also naturally flows into your home during the winter. Decreased humidity means the air will snatch moisture fast 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 pleasant at a time, a whole-house humidifier will generate that comfort around your residence.

These are just a small number of humidifier benefits you’ll receive when you put in a whole-home system.

Better Health During Cold and Flu Season

It’s typical that winter is the worst time for colds, flu and other sicknesses. That’s due to the fact you’re more susceptible to end up sick when your nose and throat are dry. Under particular airflow conditions, air at the specific humidity level can also resist the spread of some viruses. Additionally, it can combat year-round allergy symptoms.

Eases Dry Skin

If you have consistently dry skin or eczema, you know just how uncomfortable those conditions make you during winter. Installing a whole-house humidifier will help your skin hold onto more moisture.

Improved Sleep

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

Protects the Wood in Your Residence

Cabinets, flooring, furniture and most anything in your residence that’s wood suffers when humidity is too low. This is a result of 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 Necessary

Between frequent filter changes and continuous refilling, portable humidifiers expect a lot of upkeep. A whole-house humidifier only needs servicing about once a year, which can be performed in tandem with your furnace tune-up.

A steam humidifier has the least amount of maintenance since it doesn’t require a pad. It stores water in a canister and boils it into steam that gets distributed through your ductwork. Since it’s independently powered, it can be in use when the furnace isn’t running.
