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

There’s a reason why air appears drier during colder months than when it’s hotter. That’s due to the fact warmer air carries more moisture, or humidity, than colder air.

The same is true within your Richmond house. Turning on your gas furnace makes your house 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 exposed 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 Process is Part of the Trouble

The fuel your furnace needs isn’t the culprit responsible for making your house’s air seem 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 detect light from the burners when it’s heating. A newer, high-efficiency furnace is completely sealed.

A standard furnace, also known as an atmosphere furnace, pulls air from inside your home to work. Because the furnace continuously depends on air to burn, it will also use cold, dry air from outdoors, which in turn affects your house’s humidity.

High-efficiency furnaces, also called a sealed combustion furnace, are best for keeping your humidity steady. They take all their combustion air from outdoors, but it stays locked within the sealed furnace. As another bonus, they keep your residence more warm while requiring less energy. Upgrading 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 seeps into your home during cold weather. Lower humidity means the air will steal moisture rapidly from your skin, lips, nose and throat. It also contributes to static electricity.

How to Stabilize Humidity in Your House

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

These are just a couple humidifier benefits you’ll receive when you switch to a whole-home system.

Improved Health During Cold and Flu Season

It’s no surprise cooler weather is the worst time for colds, flu and other ailments. That’s since you’re more apt to become 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 alleviate year-round allergy symptoms.

Relief from Dry Skin

If you have constantly 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.

Enhanced Sleep

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

Protects the Wood in Your Home

Cabinets, flooring, furniture and basically 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 fracture. Balancing your house’s humidity at the proper level will keep your house’s furnishings looking their best.

Little Maintenance Required

Between steady 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 alongside your furnace tune-up.

A steam humidifier has the smallest amount of maintenance since it doesn’t use a pad. It stores water in a canister and boils it into steam that gets transported through your ductwork. As it’s independently powered, it can run when the furnace isn’t on.
