Your furnace plays a key role with ensuring your home is warm during colder weather. However, you can't depend on your furnace to be dependable forever. There may come a time where it needs to be repaired simply due to wear and tear on the many parts that it utilizes. Here are a few signs that your furnace is struggling and should be repaired by a professional.
Irregular Heating
Have you noticed that some rooms are hotter than others in your house, and you're not sure why? It's possible that your furnace has a problem with irregular heating, where it cannot produce enough heat that your entire home needs to stay warm. If the furnace is struggling to keep up with demand, you could end up with a situation where heat is not able to travel to the furthest vents in your home. You'll definitely want to bring in a professional to repair the problem for you.
Odd Noises
Have odd rattling, squealing, or banging sounds coming from your furnace? These are not normal, and are an indication that something is wrong and needs to be fixed. You could have a blower motor that is on its last legs, bearings that are worn down, belts that are about to crack, and other internal components of your furnace that are in the process of failing. Fix these problems now before the damage the parts cause will lead to a more expensive repair.
Short Cycling
Does the furnace turn on and then shut down quickly? This is a problem that is known as short cycling, and the furnace is shutting down to prevent damage from being caused to the system. For example, there may be a problem detected that will cause the furnace to overheat, and the furnace will turn off to prevent the temperature from getting too high. Have this problem investigated, because the short cycling process will not resolve itself for very long. You may get short bursts of furnace use at times, but the short cycling will happen again.
Odd Odors
Natural gas has a specific odor to it that is similar to rotting eggs, which is intentional due to the gas normally being odorless. If you sense that odor in your home while the furnace is running, then it likely means a problem with the gas furnace. There could be gas that is not being burned properly, which is causing it to leak into your home and get into the air. This is a serious problem that should be addressed immediately.
