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

There’s a reason why air seems drier during colder months than when it’s hotter. That’s because warmer air retains additional moisture, or humidity, than colder air. 

The same is true within your the U.S. residence. Turning on 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 residence’s air and what you can do to resolve it. 

Your Furnace’s Combustion Process is a share the Issue 

The fuel your furnace consumes isn’t the source responsible for making your residence’s air feel dry. Rather, it’s the combustion procedures. 

There are two different kinds 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 tightly sealed. 

A standard furnace, also called an atmosphere furnace, takes air from inside your house to work. Because the furnace constantly uses air to burn, it will also draw in cold, dry air from outdoors, which in turn affects your residence’s humidity. 

High-efficiency furnaces, also referred to as a sealed combustion furnace, are better at keeping your humidity even. They pull all their combustion air from outdoors, but it stays contained in the sealed furnace. As an extra perk, they keep your residence more comfy while needing less energy. Switching to an ENERGY STAR® furnace from an old furnace may 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. Decreased humidity means the air will snatch moisture rapidly from your skin, lips, nose and throat. It’s also to blame for static electricity. 

How to Stabilize 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 throughout your house. 

These are just a few humidifier benefits you’ll receive when you install 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 become sick when your nose and throat are dry. Under particular airflow conditions, air at the specific humidity level might also restrict the spread of some viruses. Additionally, it can combat year-round allergy symptoms. 

Soothes Dry Skin 

If you have consistently dry skin or eczema, you understand just how aggravating those conditions are during winter. Getting a whole-house humidifier will help your skin retain more moisture. 

Improved Sleep 

Preserving your bedroom at the ideal temperature and humidity level will keep you cozy 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 just about anything in your residence that’s wood suffers when humidity is too low. This is a result of the fact dry air absorbs moisture from the wood and causes it to crack. Having your residence’s humidity at the right level will keep your home’s furnishings looking their best. 

Little Maintenance Necessary 

Between frequent filter changes and continual refilling, portable humidifiers expect a lot of upkeep. A whole-house humidifier only needs maintenance about once a year, which can be done at the same time as 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 transported through your ductwork. As it’s independently powered, it can run when the furnace is off.
