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

There’s a reason why air feels drier in the winter than in the summer. That’s since warmer air holds additional moisture, or humidity, than colder air.

The same is true for your Toronto residence. Using your gas furnace makes your home 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 Steps are a share the Trouble

The fuel your furnace needs isn’t the culprit responsible for making your home’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 see light from the burners when it’s running. A newer, high-efficiency furnace is completely sealed.

A standard furnace, also termed an atmosphere furnace, pulls air from inside your home to work. Because the furnace consistently requires air to burn, it will also draw in cold, dry air from outdoors, which in turn reduces your home’s humidity.

High-efficiency furnaces, also known as a sealed combustion furnace, are better at keeping your humidity balanced. They draw all their combustion air from outdoors, but it stays contained in the sealed furnace. As another perk, they keep your residence more comfortable while consuming less energy. Moving 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 house during the winter. Decreased humidity means the air will rob moisture rapidly from your skin, lips, nose and throat. It’s also to blame for static electricity.

How to Even Out 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 around your residence.

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

Improved Health During Cold and Flu Season

It’s typical that cold weather is the worst time for colds, flu and other ailments. That’s due to the fact you’re more likely to end up sick when your nose and throat are dry. Under specific airflow conditions, air at the right humidity level might also hamper the spread of some viruses. Additionally, it can help with year-round allergy symptoms.

Soothes Dry Skin

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

Enhanced Sleep

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

Guards the Wood in Your House

Cabinets, flooring, furniture and basically anything in your house that’s wood suffers when humidity is too low. This is a result of the fact dry air moves moisture from the wood and causes it to crack. Having your home’s humidity at the correct level will keep your residence’s furnishings looking their best.

Little Maintenance Required

Between steady filter changes and constant refilling, portable humidifiers require a lot of upkeep. A whole-house humidifier only needs servicing about once a year, which can be performed at the same time as your furnace tune-up.

A steam humidifier has the smallest amount of maintenance since it doesn’t use a pad. It holds water in a canister and boils it into steam that gets transported through your ductwork. Because it’s independently powered, it can work when the furnace is off.
