It shouldn’t come as a surprise that furnaces are indeed a great piece of invention. They help in heating our homes efficiently and thereby make us feel comfortable. But, just like any other machinery or appliance, there can be times when something will go wrong with them, thereby making them extremely dangerous.
So, if you’re planning to inspect a home that comes with a combustion furnace along with a professional home inspector, then multiple factors should be considered during the inspection to ensure that it is working safely. Therefore, in this guide, we’ll help you learn the process through which a combustion furnace can be ideally inspected.
How Does A Combustion Furnace Work?
Combustion can be defined as the process of burning something. A combustion furnace usually burns gas so that heat can be produced to warm-up the house. It should be understood that fire cannot burn without the presence of oxygen. That’s why some combustion furnaces have sealed combustion chambers while others have atmospheric ones.
Professional home inspection in Orlando FL services states that an atmospheric combustion furnace generally pulls air (or oxygen) from the interior atmosphere of the house. On the other hand, a sealed combustion furnace pulls air from the outside.
When we compare these two types of combustion furnaces, it’s clear that sealed ones are the better option because not only no oxygen is used from the house’s interior atmosphere of the house but also there’s no accumulation of carbon monoxide inside the home.
The Need For Fresh Air
Combustion furnaces that are atmospheric require adequate air to be able to burn. So, if they’re placed inside a small room or basement, the doors & windows must be kept open, so that enough ventilation could be provided. Without such ventilation, the overall combustion process would become incomplete and thereby negative air pressure would build up inside your home.
Furthermore, there is a massive risk of carbon-monoxide being sucked into the home, which is known as a backdraft. Home inspectors, when checking a combustion furnace, specifically look for any instances of backdraft. If moist or warm air is coming out from the furnace, then there’s a serious backdraft issue with the furnace.
Rusting Is A Bad Sign
Apart from detecting any backdraft, home inspectors also look for any instances of rust within the combustion furnace. Since condensation is a common phenomenon within the furnace (due to heating & cooling), which can lead to rusting on the hood of the furnace.
If you notice such serious issues with your combustion furnace, it’s suggested that you get your furnace inspected & fixed by a reliable furnace repairing company. And in case you want to learn more about home inspection, simply contact us today.
