It would be easy to ignore some of the noises coming out of your furnace, right? But that doesn’t always mean we should ignore them. The thing is, it’s too easy to ignore them and deny that something could be wrong with our heaters because fixing it is an expensive hassle.
But the fact of the matter is, there are some noises that just shouldn’t be ignored. A loud rattling, for instance, may just be a sign that a component is loose and needs to be tightened. Or, it could be something way more serious that could threaten the functionality of your heater and even your home safety. Read on to learn some of the furnace noises you should never ignore, and why.
A loud screech coming within your furnace is most likely an indication that the blower motor component isn’t working as it should. A malfunctioning blower motor means that the heat generated by the system won’t be able to actually circulate through your ventilation system and into your home.
This may just mean that your blower motor is in need of lubrication. The good news is, this is a natural result of wear and tear and something that our technicians can easily resolve for you. But in order to diagnose this issue, you have to call us to begin with!
If you hear something that resembles metal-on-metal, then you probably are hearing metal-on-metal. This is probably a sign of a problem with the blower wheel of your furnace. If this is the case, then a professional needs to be called right away! But you won’t know for sure that this is the problem until you call us.
So, when you hear clanking, turn your furnace off first and foremost. Then, dial our number!
Banging or Booming
Generally speaking, the boom or bang that you hear coming from your furnace, if it’s upon startup, is a sign of a dirty burner. This can be a dangerous problem to have. The noise you’re hearing can be caused by a delay in ignition due to dirt and grime buildup. What happens is that the gas builds up under it, it has to burn through it and a small explosion occurs inside the system.
Accessing the burners yourself is not safe—you could end up doing more harm than good, and you don’t want to end up spending more money in the long run. It’s always a better idea to call in a pro, especially when working with any type of gas-powered appliance.
A slight rattling is an okay sound to hear, generally speaking. It may be your ductwork fluctuating with the temperature changes. But if you hear a heavy rattling coming from the system, you should never just assume this. Heavy rattling can cause the furnace itself to rattle and can lead to a cracked heat exchanger.
Heat exchangers are the components responsible for actually heating the air that enters your home. Combustion gas enters their chambers, and the air blows over it. If there’s a crack in a heat exchanger, however, it can lead to carbon monoxide (CO) exposure in your home, which can be very harmful.
