Safety concerns and proper ventilation
Because gas-powered furnaces generate warmth by burning fuel, they have safety controls that require regular inspections for their proper operation and your peace of mind. One of the most important things we check is whether your furnace has proper ventilation. This ensures that carbon monoxide (CO) and other byproducts of combustion cannot build up in the home. Carbon monoxide, an odorless gas produced when fuel is burned, can cause carbon monoxide poisoning, if it accumulates in large amounts in your home. It can be fatal.
The risk of your furnace overheating A furnace that is not operating properly or that has a clogged air intake can overheat. Over time, a furnace that is working harder to heat will run longer, causing the furnace to run hotter than it should. If this is not addressed, it can become dangerous and cause your heating system to malfunction, stop, or cause a fire. Identification of older, inefficient furnaces If your home’s furnace is 15 years or older, you might have what is called a natural draft or gravity furnace instead of a forced-air furnace that is common today. This type of gas-powered furnace was commonly installed in the early 1990s and earlier. It was an economical choice and heat was distributed naturally as hot air rises. These units were phased out because they were inefficient (80%), requiring the furnace to burn much more fuel to heat a room. Catching problems while they are easy to fix Scheduling a heater check for regular inspection and maintenance of your gas-fired furnace is an investment in the longevity of your HVAC system. Well-maintained heaters can last 20 years or more, especially if you take care of them year after year.
