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

There’s a reason why air appears drier in the winter than in the summer. That’s since warmer air carries extra moisture, or humidity, than colder air.

The same is true inside your Ravenna residence. Starting 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 likely to get sick.

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

Your Furnace’s Combustion Procedures are a share the Problem

The fuel your furnace consumes isn’t the source responsible for making your house’s air seem dry. Rather, it’s the way it combusts.

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 totally sealed.

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

High-efficiency furnaces, also known as a sealed combustion furnace, are used for keeping your humidity steady. They take all their combustion air from outside, but it stays trapped within the sealed furnace. As an extra advantage, they keep your house more comfy while needing less energy. Upgrading to an ENERGY STAR® furnace from an old furnace may save you as much as 40% on heating costs, according to Lennox®.

Besides combustion, cold air also naturally seeps into your home during colder weather. Reduced 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 Home

Using a humidifier is the better way to manage your home’s humidity in the winter. You have two choices, a portable humidifier or a whole-house humidifier. While a portable humidifier can only make one room comfy at a time, a whole-house humidifier will generate that comfort around your residence.

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

Better Health During Cold and Flu Season

It’s no surprise cold weather is the worst time for colds, flu and other sicknesses. That’s due to the fact you’re more likely to get sick when your nose and throat are dry. Under certain airflow conditions, air at the correct humidity level might also hamper the spread of some viruses. In addition, it can help with year-round allergy symptoms.

Soothes Dry Skin

If you have constantly dry skin or eczema, you realize just how uncomfortable those conditions can be during winter. Installing a whole-house humidifier will help your skin retain more moisture.

Improved Sleep

Maintaining your bedroom at the right 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.

Guards the Wood in Your House

Cabinets, flooring, furniture and most anything in your residence that’s wood doesn’t like it when humidity is too low. This is due to the fact dry air pulls moisture from the wood and causes it to crack. Balancing your house’s humidity at the right level will keep your house’s furnishings looking their best.

Little Maintenance Needed

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

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