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

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

The same is true for your Saint Charles home. Starting your gas furnace makes your house feel warmer but can also dry out the indoor air. Dry air can transport a whole host of ailments, like dry skin, cracked lips and make you more exposed to getting sick.

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

Your Furnace’s Combustion Process is Part of the Problem

The fuel your furnace needs isn’t the culprit responsible for making your residence’s air seem dry. Rather, it’s the combustion process.

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 working. A newer, high-efficiency furnace is entirely sealed.

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

High-efficiency furnaces, also known as a sealed combustion furnace, are ideal for keeping your humidity even. They pull all their combustion air from your home’s exterior, but it stays contained inside the sealed furnace. As another perk, they keep your home more comfy 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 house during colder weather. Lower humidity means the air will snatch moisture quickly from your skin, lips, nose and throat. It also causes static electricity.

How to Balance 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 transport that comfort throughout your residence.

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

Better Health During Cold and Flu Season

It’s no surprise cooler weather 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 right humidity level might also slow the spread of some viruses. Additionally, it can reduce year-round allergy symptoms.

Soothes Dry Skin

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

Enhanced Sleep

Preserving your bedroom at the ideal 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.

Protects the Wood in Your Home

Cabinets, flooring, furniture and just about anything in your house that’s wood suffers when humidity is too low. This is because of the fact dry air draws moisture from the wood and causes it to split. Having your house’s humidity at the proper level will keep your residence’s furnishings looking their best.

Little Maintenance Needed

Between consistent filter changes and constant refilling, portable humidifiers depend on a lot of upkeep. A whole-house humidifier only needs a tune-up about once a year, which can be completed in tandem with your furnace tune-up.

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