Why is My Furnace Making That Weird Sound?

Your furnace operates at a relatively low noise level. The few sounds it does make are not disruptive and usually go unnoticed as the winter drags on. That’s why a sudden change can indicate your furnace is suffering from a malfunction. The type of noise your furnace is emitting can help you pinpoint the cause behind the sound. If your system is making an unusual noise, and you’re concerned, keep reading to find out what the sound means for the health of your furnace.

Rattling…

A rattling or banging sound can indicate a component in your furnace has come loose. Unfortunately, without inspecting the unit there is no way to tell which part is no longer secure. Ignoring the sound can lead to the malfunction getting worse, meaning the rattling will grow louder, and the loose component will completely disconnect. If this happens, turn your furnace off immediately, and contact a HVAC specialist. Having your system inspected before the rattling or banging increases in volume is crucial when it comes to saving your furnace from a serious breakdown, and keeping your repair cost manageable!

Squealing…

A furnace that squeals points to a blower motor that lacks proper lubricant between its moving parts. The friction created as the components in the motor rub together produces the unfortunate noise. During a yearly inspection, a HVAC technician examines the blower motor to ensure it has enough oil, and if it doesn’t, they add the needed amount. If you didn’t get your furnace serviced before the heating season started, and your unit is squealing, it’s time to give us a call.

Clicking…

Clicking sounds coming from your furnace can signal an issue with your unit’s igniter. If the sound lasts for only a minute or two, the igniter is likely dirty and needs to be cleaned. A problem with the flame sensor is also a possibility. The flame sensor acts as a safety mechanism, which ensures there’s a flame present when the gas valve opens. Without a flame sensor, gas would be released with no flame to ignite it. If the sensor is malfunctioning, it may not sense a flame even when a flame is present. If this happens, the gas valve will close prematurely. Problems with your furnace igniter should be addressed immediately by a highly trained HVAC technician.

When your furnace works to warm your home, the only sounds you should hear are a quiet hum and a rush of air flowing through your vents. If those noises are replaced by a sound you’re not familiar with, please contact our team here at Cunningham Associates to schedule an appointment.

Avoid Serious Health Problems by Working with a Heating Contractor

Many problems can arise with heating in your home and it is not one of those things you can choose to ignore. At best, not having sufficient heat will make you and your family uncomfortable. Then again, in the worst-case scenario, it can lead to serious health problems.

Problems That Arise with a Lack of Heating

Not having sufficient heat can lead to someone getting sick. When you catch a chill due to a lack of heating in the home, it can lead into a long-term illness.

Plus, not having sufficient heat also means that you might end up buying a number of space heaters which will run up your electricity bill.

People have also been known to do senseless things like turning on the oven and leaving it open in order to make the house warmer. This is very dangerous as the gas can spread throughout the house and cause an explosion. Even if there is no explosion, you and your loved ones might inhale a lot of gas which is terrible for your health.

Therefore it’s very important to have your heating working properly. This will protect you and your loved ones in the long run.

Advantages of Working with the Same Heating Contractor

The best thing is to have a heating contractor on speed dial so that you can request service for your heating problems and get everything take care of as soon as possible. It’s a good idea to use the same person no matter what problems you might have. Once you’ve worked with a heating contractor and you know that they do a good job, you can keep working with them.

The advantage of this is that the contractor will understand your heating system inside and out. So when you call them with a problem, they’ll probably already have the solution. This saves time and money in the long run.
