If your home's gas furnace has been in your home for more than a decade or so, you may be wondering whether or not it is still doing its job of heating your house as well as whether or not it is time to get a new one. If so, look for the signs discussed below that your old furnace may be on its last leg and should be replaced.
1. Furnace No Longer Distributes Heat Evenly Throughout Your House
One sign that your gas furnace is reaching the end of its lifespan is when you start noticing that it can no longer evenly distribute heat throughout your house. In one room, especially one that is closest to the furnace, you may find that you get so hot you can hardly breathe.
In a room far away from the heating unit, however, you may find that it can barely keep the space warm. You may also find rooms in between these extremes that may feel cold one day then too hot the next.
If the furnace is wearing down, the motor and/or blower may not have the ability to consistently heat the air and blow it through your home. If this is the case, the cost of repairing these parts may not be worth it, especially if others start breaking down because of age. It may be better to just go ahead and replace the entire unit.
2. Furnace Makes Loud Booming Noise When It First Kicks On
Another sign that it is time to replace your home's old gas furnace is when you start noticing a loud booming noise almost every time it kicks on. This sound is most likely caused by a delay in the initial flow of gas that feeds the pilot and burner.
Because of the delay, the gas will start to gather in the line before it forces its way through. As the accumulated gas ignites, the excess gas causes a mini-explosion, which creates the sound and can also cause vibrations through the furnace.
If you suspect that your furnace has gas emission issues and/or it no longer heats your house evenly, it may be time to think about getting a new one. If you believe that this is the case, contact an HVAC contractor who offers heating replacement services for personalized assistance with choosing a new furnace as well as discuss your options for having it installed in your home.
