5 Top Problems With A Gas Furnace
Without question, gas furnaces can be an efficient way to heat your home. However, as efficient as a gas furnace may be, these units can still have problems. Generally, there are specific problems that spur a homeowner to call an HVAC contractor for furnace repair. Check out the top five problems below.
Pilot Light Won't Stay Lit
When the pilot light will not stay lit in your gas furnace, it is impossible for the heat exchanger to heat up and provide heat to your home. There can be several reasons why a pilot light will not stay ignited even though you see the flame initially spark to life. For example, problems with the gas supply line or simply a dirty distribution point on the line can prevent achieving a stable flame.
Blower Bearings Are Worn Out
The blower system is responsible for pushing air across the heat exchanger to spread heated air throughout your home. The blower contains a lot of parts and components, but the bearings are one of the most common components to wear out. You may hear the furnace making a lot of noise when the system kicks on. Or, you may notice the blower is not producing heated air as usual.
Damaged Heat Exchanger
The heat exchanger is a system of coils that heats up within the furnace when the system is powered on. These heated coils are directly responsible for supplying heat from a gas furnace, but they can become damaged with age. Usually, a damaged heat exchanger will render the furnace useless because it will no longer supply heat.
A non-responsive thermostat is one of the most common reasons for furnace repair calls, with or without a gas furnace. Thermostats tend to have a limited life span, which means they can suddenly stop responding to your inputs and settings. However, there can also be thermostat failure if there is an issue with the power supplied to the unit.
While gas leaks are a rarity with gas-powered furnaces, they can happen. Usually, a homeowner will smell a gaseous odor coming from around their furnace or pilot light. These issues often come from sections of the gas line that need to be replaced, but they may also come about if there is damage to the pilot light. For example, if the pilot light's flame starter is not working, the gas provided to ignite the pilot light may leak out instead of being burned.
