Humidity in House & How to Manage your Home’s Humidity

The Importance of Your Furnace And Humidifier In Managing Home’s Humidity Levels

Winter weather means the furnace starts up and outside and inside humidity levels start to have a greater impact on your health. The cold air forces your furnace to turn on, which leads to more dry air inside your home. Humidity levels definitely affect your home’s comfort, so managing indoor humidity can make the time you spend there much more enjoyable. 

If you’re like most people, listening to your furnace turn on and off can create anxiety about your heating costs.  What you may not realize is the same weather that makes your furnace turn on can also reduce humidity and cause your sinuses to dry out.  The low humidity can also decrease the efficiency of your furnace and air conditioning units.

What is Humidity, and How Does It Impact Your Furnace Efficiency and Health?

Relative humidity refers to the percentage of water vapour present in the air at a given temperature. For example, when the relative humidity is 50%, the air is holding half the moisture it’s capable of holding. The air’s ability to hold water decreases as the temperature goes down and increases as the temperature goes up.

The right humidity levels help your home feel cool in the summer and warm in the winter.

When Your Furnace Turns On, You’ll Experience Low Humidity in Action

On a winter day, the outside temperature might be -12° F with 70% humidity.

When the cold outside air gets into your home, and your furnace heats it to 21° C, the air expands. While the moisture in the air remains the same, the relative humidity is significantly reduced. This means that the outside cold air with 70 percent humidity has an indoor relative humidity of only 6 percent. That’s more than four times drier than the Sahara Desert.

The dry interior air will steal moisture from wherever it can find it, including your body. As moisture evaporates off your skin, you feel cooler. When you feel cooler, you tend to turn up your thermostat and the cycle continues, which can become expensive.

What Should Home Humidity Levels Be?

A range of 45% – 55% humidity is recommended to manage indoor comfort levels.

        Comfortable: 30% – 60%

        Recommended: 45%- 55%

        High: 55% – 80%  

To keep your home feeling comfortable during the winter, keep your furnace set at around 68 degrees F, with relative humidity at the recommended level of 45% – 55%.

Problems of Low Indoor Humidity

As the heat travels through your HVAC system, it sends out dry air to warm your home. This dry air creates some problems, but having a whole house humidifier will improve, prevent, or eliminate the following:

        Static electricity

        Dry, itchy skin and hair, chapped lips

        Susceptibility to colds, respiratory illness and sinus infections

        Viruses and germs thrive, spreading colds and flu

        Damage to wood furniture and floors, trim and framing around windows and doors

        Worsened asthma and allergy symptoms.

        Wood, furniture, flooring, moulding, trim and framing around doors and windows can become cracked and damaged

How Your Furnace And Your Humidity Work To Keep You Healthier Indoors

To combat the problem of low humidity in your home during winter, relative humidity levels should be maintained at the recommended 45% – 55% range to reduces the air’s need to replenish moisture by taking it from your skin.

As a result, you can actually turn down your thermostat a few degrees and still maintain your comfort and warmth. Your furnace can use less energy, you will remain comfortable, and you will have lower energy bills.

To humidify the air in your home, JD Swallow recommends installing a whole home humidifier that coordinates directly with your furnace or boiler system. These humidifiers work automatically to ensure the air in your home is at optimum humidity levels to keep you comfortable.

Typically, these whole home systems cost several hundred dollars, but the energy savings make it a wise investment. They provide other benefits, as well.
