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.\u00a0<\/p>\n\n\n\n

You may have heard that using a gas furnace will dry the air in a house. It\u2019s accepted as conventional wisdom. But is there actually any truth to this? We\u2019ll look more into this below and help you make a decision about any future heating installation in Forsyth, GA<\/a> you may need.<\/p>\n\n\n\n\n\n\n\n

Myth or Reality: Does a Gas Furnace Dry the Air?<\/strong><\/h2>\n\n\n\n

Contrary to popular belief, a gas furnace itself does not dry out the air in your home. Here\u2019s what\u2019s really happening:<\/p>\n\n\n\n

Older atmospheric furnaces<\/strong>\u2014those that pull air from inside your home for combustion\u2014can 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\u2019s actually the influx of dry, outdoor air that\u2019s to blame.<\/p>\n\n\n\n

Modern sealed combustion furnaces<\/strong>, on the other hand, solve this issue by using air from outside for combustion. These systems are tightly sealed and don\u2019t create the same air deficit. Because they don\u2019t pull air from inside your home, there\u2019s no need to replace it with outdoor air, which means your indoor humidity levels are more stable.<\/p>\n\n\n\n

The Advantages of a Sealed Combustion Furnace<\/strong><\/h2>\n\n\n\n

Beyond preventing the air deficit issue, sealed combustion furnaces offer several other benefits:<\/p>\n\n\n\n
