Cold Air From Your Furnace? Here are 4 Reasons

February 25, 2021 Uncategorized

A furnace is a home appliance that’s powered by either gas, oil, or electricity, which gives you comfortable temperatures in the midst of cold weather. Your thermostat settings indicate your desired temperature, telling your furnace what to do. Your furnace’s control board then ensures that your system’s safety features are all working. Then, the furnace ignites, heats the air, which is delivered via a network of ducts. This, in a nutshell, is how a furnace works.

However, there are times when your heating system fails to deliver heat and transports cold air instead. In this article, we will give you four reasons why such a thing happens.
