Does a Gas Furnace Dry the Air in a House?

In the previous post, we looked at the effects of dry air in a house and how installing a whole-house humidifier can make an enormous difference in both comfort and energy savings. Today, we want to look at the issue of dry air again, but from a different perspective. 

You may have heard that using a gas furnace will dry the air in a house. It’s accepted as conventional wisdom. But is there actually any truth to this? We’ll look more into this below and help you make a decision about any future heating installation in Forsyth, GA you may need.

Myth or Reality: Does a Gas Furnace Dry the Air?

Contrary to popular belief, a gas furnace itself does not dry out the air in your home. Here’s what’s really happening:

Older atmospheric furnaces—those that pull air from inside your home for combustion—can create an air deficit. To compensate, the house pulls in outdoor air through small cracks and leaks in the building envelope. During winter, this outdoor air tends to be much drier than the air inside your home. As a result, it feels like the furnace is causing dryness, but it’s actually the influx of dry, outdoor air that’s to blame.

Modern sealed combustion furnaces, on the other hand, solve this issue by using air from outside for combustion. These systems are tightly sealed and don’t create the same air deficit. Because they don’t pull air from inside your home, there’s no need to replace it with outdoor air, which means your indoor humidity levels are more stable.

The Advantages of a Sealed Combustion Furnace

Beyond preventing the air deficit issue, sealed combustion furnaces offer several other benefits:

  • Improved Efficiency: By using outside air for combustion and reducing energy losses, sealed systems operate more efficiently.
  • Enhanced Safety: Sealed combustion prevents the back-drafting of combustion gases, reducing the risk of carbon monoxide leaks.
  • Reduced Noise: These systems are designed for quieter operation, making them less disruptive.
  • Better Comfort: Because they help maintain more consistent humidity levels, they contribute to a more comfortable indoor environment.

Maintaining Comfortable Humidity Levels

Even with a modern furnace, winter air tends to be naturally dry. To combat this, consider adding a whole-house humidifier to your HVAC system. A humidifier not only improves comfort but can also help you save on heating costs. Proper humidity levels make the air feel warmer, so you can lower your thermostat without sacrificing comfort.
