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

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

The same is true inside your Austin residence. Turning on your gas furnace makes your residence feel warmer but can also dry out the indoor air. Dry air can bring a whole host of ailments, like dry skin, cracked lips and make you more likely to get sick.

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

Your Furnace’s Combustion Steps are a share the Trouble

The fuel your furnace uses isn’t the source responsible for making your home’s air seem dry. Rather, it’s the way it combusts.

There are two different styles 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 completely sealed.

A standard furnace, also known as an atmosphere furnace, pulls air from inside your house to function. Because the furnace constantly uses air to burn, it will also pull cold, dry air from outdoors, which in turn reduces your home’s humidity.

High-efficiency furnaces, also referred to as a sealed combustion furnace, are ideal for keeping your humidity steady. They take all their combustion air from your home’s exterior, but it stays contained within the sealed furnace. As an additional advantage, they keep your house more warm while requiring less energy. Moving to an ENERGY STAR® furnace from an old furnace could save you as much as 40% on heating costs, according to Lennox®.

Other than combustion, cold air also naturally moves into your residence during cold weather. Lower humidity means the air will rob moisture fast from your skin, lips, nose and throat. It’s also to blame for static electricity.

How to Even Out Humidity in Your Residence

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

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

Better Health During Cold and Flu Season

It’s common that winter is the worst time for colds, flu and other ailments. That’s because you’re more apt to get sick when your nose and throat are dry. Under specific airflow conditions, air at the right humidity level can also resist the spread of some viruses. Additionally, it can weaken year-round allergy symptoms.

Relief from Dry Skin

If you have chronically dry skin or eczema, you realize just how aggravating those conditions are during winter. Adding a whole-house humidifier will help your skin hold onto more moisture.

Improved Sleep

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

Protects the Wood in Your Home

Cabinets, flooring, furniture and most anything in your home that’s wood doesn’t like it when humidity is too low. This is because of the fact dry air pulls moisture from the wood and causes it to split. Keeping your home’s humidity at the proper level will keep your residence’s furnishings looking their best.

Little Maintenance Needed

Between regular 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 done in tandem with your furnace tune-up.

A steam humidifier has the lowest amount of maintenance since it doesn’t use a pad. It retains water in a canister and boils it into steam that gets moved through your ductwork. Because it’s independently powered, it can be in use when the furnace isn’t on.
