Does your furnace dry out the air in your home?

Like many homeowners you probably feel the effects of winter in your home, especially when it comes to dry air. Dry air on your skin, hair, and in your breathing airways can be an irritating nuisance. There are many things you can do to prevent and alleviate dry air in your home but what actually causes it in the first place? Does your furnace dry out the air in your home or is it something else?

Does your furnace dry out the air?

Dry air inside of your home is usually caused by getting too much air in from outside. In some circumstances, it may also have to do with someone in your household running the dehumidifier without knowing.

But how does a furnace dry out the air?

Air leaks

If you haven’t properly sealed your windows, doors, attic, and basement, you’re letting in a lot of dry outside air. Not only does this air make your indoor air feel drier, it also makes your home feel cooler. Because the temperature inside is colder, you’re more apt to crank up your furnace, making it seem like the dry air issue is linked to heating.


Ventilation throughout your home is recommended but it can also mean that the dry air from outdoors has a way to find its way inside. Again leading to dry air and coldness, resulting in you turning up the heat and tricking you into thinking the problem you’re facing with dry air is linked to your furnace.

Leaky ductwork

Leaks in your air ducts, especially those in areas like your attic, basement, and garage, let cold air from outside into your living areas. Not only does this make your home chilly, it also causes your home energy efficiency to decline and your energy bills to skyrocket as your crank your heater up to try and maintain warmth throughout your home.

How to solve dry air problems

If the air is dry, don’t suffer any more than you already are by keeping the temp down low because you think the furnace is contributing to the dryness. Instead, try these solutions to help get the humidity levels higher so you can go back to breathing easy:

  • Wash your clothes and allow them to air dry inside your home
  • Boil water on the stove in an open container
  • Wash your dishes by hand and allow them to air dry
  • Leave your bathroom door open as you shower
  • Get a few houseplants
  • Invest in a whole-home humidifier (the best option)

A humidifier will help remedy your dry air issues and there are dozens of options available based on the size of your home, your budget, and your comfort preferences. Talk with an experienced HVAC professional to find the right solution and get a free quote for your home needs.
