Why Your Gas Furnace Creates Dry Air in Your Residence and How to Solve It

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

The same is true within your Miami home. Starting your gas furnace makes your house feel warmer but can also dry out the indoor air. Dry air can bring a whole host of ailments, such as dry skin, cracked lips and make you more likely to get sick.

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

Your Furnace’s Combustion Steps are a share the Issue

The fuel your furnace needs isn’t the source responsible for making your house’s air appear 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 on. A newer, high-efficiency furnace is entirely sealed.

A standard furnace, also known as an atmosphere furnace, takes air from inside your house to combust. Because the furnace constantly needs air to burn, it will also pull cold, dry air from outdoors, which in turn reduces your house’s humidity.

High-efficiency furnaces, also referred to as a sealed combustion furnace, are better at keeping your humidity steady. They pull all their combustion air from your home’s exterior, but it stays locked within the sealed furnace. As an added perk, they keep your residence more cozy while consuming less energy. Switching to an ENERGY STAR® furnace from an old furnace might save you as much as 40% on heating costs, according to Lennox®.

In addition to combustion, cold air also naturally seeps into your residence during colder weather. Decreased humidity means the air will snatch moisture quickly from your skin, lips, nose and throat. It also causes static electricity.

How to Balance Humidity in Your Home

Using a humidifier. While a portable humidifier can only make one room comfortable at a time, a whole-house humidifier will transport that comfort throughout your house.

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

Better Health During Cold and Flu Season

It’s no surprise winter is the worst time for colds, flu and other illnesses. That’s since you’re more susceptible to end up sick when your nose and throat are dry. Under specific airflow conditions, air at the correct humidity level might also restrict the spread of some viruses. In addition, it can help with year-round allergy symptoms.

Relief from Dry Skin

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

Improved Sleep

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

Protects the Wood in Your Home

Cabinets, flooring, furniture and most 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. Having your residence’s humidity at the right level will keep your residence’s furnishings looking their best.

Little Maintenance Necessary

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

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