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

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

The same is true within your the U.S. home. Using 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 vulnerable to getting sick. 

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

Your Furnace’s Combustion Steps are a Portion of the Problem 

The fuel your furnace consumes isn’t the culprit 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 tightly sealed. 

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

High-efficiency furnaces, also referred to as a sealed combustion furnace, are used for keeping your humidity even. They pull all their combustion air from outside, but it stays trapped within the sealed furnace. As an added advantage, they keep your residence more comfy 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®. 

Besides combustion, cold air also naturally seeps into your residence during colder weather. Reduced humidity means the air will rob moisture quickly from your skin, lips, nose and throat. It also contributes to static electricity. 

How to Even Out 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 house. 

These are just a small number of humidifier benefits you’ll acquire when you switch to a whole-home system. 

Improved Health During Cold and Flu Season 

It’s common that winter is the worst time for colds, flu and other illnesses. That’s due to the fact you’re more likely to get sick when your nose and throat are dry. Under specific airflow conditions, air at the specific humidity level may also restrict the spread of some viruses. In addition, it can reduce year-round allergy symptoms. 

Relief from Dry Skin 

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

Enhanced Sleep 

Maintaining 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. 

Guards the Wood in Your Home 

Cabinets, flooring, furniture and generally anything in your residence 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 residence’s humidity at the correct level will keep your home’s furnishings looking their best. 

Little Maintenance Needed 

Between frequent filter changes and constant refilling, portable humidifiers rely on a lot of upkeep. A whole-house humidifier only needs servicing about once a year, which can be done alongside your furnace tune-up. 

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