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

There’s a reason why air feels drier in the winter than when it’s warmer. That’s because warmer air carries extra moisture, or humidity, than colder air. 

The same is true within your the U.S. home. Starting 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 residence’s air and what you can do to counter it. 

Your Furnace’s Combustion Steps are a share the Issue 

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

There are two different types 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 totally sealed. 

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

High-efficiency furnaces, also known as a sealed combustion furnace, are better at keeping your humidity balanced. They pull all their combustion air from your home’s exterior, but it stays contained inside the sealed furnace. As an additional bonus, they keep your residence more comfy while needing 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 drifts into your home during cold weather. Lower humidity means the air will snatch moisture fast from your skin, lips, nose and throat. It’s also to blame for 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 generate that comfort throughout your house. 

These are just a few humidifier benefits you’ll get when you install 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 due to the fact you’re more apt to become sick when your nose and throat are dry. Under particular airflow conditions, air at the specific humidity level can also slow the spread of some viruses. Additionally, it can alleviate year-round allergy symptoms. 

Relief from Dry Skin 

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

Improved Sleep 

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

Guards the Wood in Your House 

Cabinets, flooring, furniture and generally anything in your residence that’s wood suffers when humidity is too low. This is because of the fact dry air pulls moisture from the wood and causes it to fracture. Keeping your home’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 depend on a lot of upkeep. A whole-house humidifier only needs servicing about once a year, which can be completed 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 distributed through your ductwork. Because it’s independently powered, it can run when the furnace isn’t on.
