Lennox Furnace Making Strange Noises? Here’s What to Do

Lennox Furnace Making Strange Noises? Here's What to Do

If your Lennox furnace starts making strange noises, it’s time to consider the causes and take action. Strained mechanical parts, clogged filters, and poor maintenance can all lead to strange noises coming from your furnace. For your sanity, and the comfort of your family, it’s vital to diagnose and rectify the issue. What follows is a guide to help you identify the issue and remedy the troubling sounds coming from your Lennox furnace.

What are the Causes of Strange Furnace Noises?

Most furnace noises are created by some form of mechanical friction. This can occur between moving parts, or develop within an internal component embedded within the furnace. There are a few common causes for odd noises, including:

Mechanical Parts Stress

If your furnace's air filtering system is clogged, mechanical components can become strained. As air filters get dirty and blocked, the pressure in the furnace's incoming air line increases, compressing the components. The stress on the motor can create, or amplify, a grinding noise.

Suffocating Blower Motors

Your furnace's blower motor is responsible for circulating the heated air throughout your living space. The motor is secured to the furnace's chassis, and features bearings that can become dry or overworked. This can lead to a squeaking, or squealing noise.

Ductwork Resonance

The metal of your ductwork naturally vibrates with the rushing air, and if it's loose it can amplify these sounds. People often report hearing a strange “whooshing” sound when this problem is present.

Improper Maintenance

If your furnace has been chronically neglected and hasn't had maintenance in several years, strange noises can alert you to a problem. As time passes, combustion byproducts build up in your furnace's casing. Overweighted shift motors can lead to a weird grinding sound, and sticky gas valves might sound like a tapping, or clicking sound.

How to Diagnose Strange Noises

To diagnose strange noises in your Lennox furnace, don't rely solely on your own perceptions. After all, you're unfamiliar with this type of machinery, and interpreting odd noises isn't easy.

Instead, take a step-by-step approach to determine the source of the racket. Start by going through the basics: check your thermostat, filters, and other components. Once you've completed a visual inspection, it's time to get a little deeper into the problem.

1. Run the Furnace

If all your basic checks seem okay, it's time to turn on the fan and run through a full cycle. Don't feel comfortable doing this? Don't worry, it's time to call in a professional. A certified HVAC technician will be able to quickly diagnose the issue.

2. Check the Blower Motor

Is the fan set to the proper speed? Adjusting the speed may help reduce the noise. Make sure the air handler is properly sized and sealed, that the cover panels are secure, and that the fan motor is still in good shape.

3. Look for Air Leaks

Look for any leaks or gaps in the ductwork. If there are any, it's time to seal them up. Leaks can lead to a loud whooshing noise when the fan is running, so if the repairs are necessary, get them done quickly.

4. Clean or Replace Filters

If the filters are clogged, air flow will be restricted and your components will be strained. Clean your furnace's filters every six months, or swap them out for new ones at least once a year. This will ensure that your system is functioning optimally.

How to Stop Strange Noises

Once you've identified the source of the strange noises, it's time to take action. A certified HVAC technician will be able to diagnose and repair the problem quickly, but if you're confident in your technical abilities there are some steps you can take to fix the issue yourself.

Repair Ductwork

If you notice any loose ductwork, repair or replace it. Leaky ductwork can amplify any noise coming from your furnace, so it's important to seal up any gaps or cracks.

Tighten or Replace Motors

If your blower motor is dry or aging, it could be the cause of the noise. Lubricate the motor, or have a technician replace it if needed.

Service Your Furnace

Have your furnace serviced by a qualified professional at least once a year. A routine start-up inspection and maintenance check will identify and rectify any issues before they start to cause problems.

Upgrade Your System

If your furnace is more than 10 years old and plagued with problems, it might be wise to consider an upgrade. Modern systems are far more efficient and reliable, and can provide substantial savings in the long run.

If you're hearing strange noises coming from your Lennox furnace, don't ignore the issue. Mechanical problems can get worse if they're not attended to, and proper maintenance and inspection can help detect the source early.
