Why Does My Furnace Sound Like a Washing Machine or Other Unusual Sounds?

December 1, 2023

Is your furnace making strange noises that remind you of a washing machine? This is a normal occurrence as your HVAC system will often make a whirring noise that sounds like a washing machine.

This is no reason to be concerned. However, there are other sounds to listen for that could indicate that you need to replace your furnace.

Sounds That Indicate Your Furnace Needs to be Repaired

There are a range of noises to listen for when it comes to your furnace, including:

Scraping sounds: If your furnace is making metallic scraping noises, this means that metal components of the machinery are rubbing against each other. This could mean that the blower is out of alignment and is rubbing the housing. The blower will keep loosening, which will lead to it hitting or rubbing against other components. This will cause more friction and wear and will also lead to more damage to the unit. If you hear this type of noise, turn off the unit and contact a technician for repairs.

Thumping/Vibrating: If your furnace is making loud, thumping or vibrating noises, this could indicate that the blower wheel is out of balance or has come loose. This can be a serious issue and should be immediately addressed by a professional HVAC technician.

Rattling: Rattling noises are often caused by something obstructing the blower fan. First, check for any debris or objects caught inside the furnace. If there are none, then it could mean that a component has come loose and is vibrating when the unit is running. This can lead to further damage if not addressed quickly. Shut off the unit and contact a technician to evaluate your furnace.

Squeaking: If you hear a high-pitched squeaking sound, it could mean that the blower motor is malfunctioning and needs to be replaced. This can also indicate that there is an issue with the belt or bearings in the system. It’s best to have a professional inspect and repair your furnace as soon as possible.

Thwapping: This noise likely means that something is caught in the fan blades located inside of the motor. You will hear this noise come and go, and it will not typically affect the operation of the furnace. It can increase the wear and tear on your furnace, so it is important to have the obstruction removed as soon as possible.

Booms/Bangs: Loud noises like this can mean that your furnace has dirty burners that are delaying the ignition. It can also mean that the sheet metal duct is flexing due to the changes in pressure.

Whistling/Humming: Whistling may indicate a leak in the high-pressure system, ductwork, or refrigerant, whereas a humming can mean that the transformer is going bad.

Additional Signs Your Furnace Needs to be Repaired or Replaced

In addition to unusual noises, there are other signs that indicate you may need a furnace replacement in Pittsburgh. These include:

  • Increase in energy bills
  • Inconsistent or inadequate heating throughout your home
  • Frequent breakdowns and repairs

These are all signs that something is not functioning properly. Leaving your furnace in poor condition can lead to a breakdown, leaving you in the cold this winter.

When Should You Consider Furnace Replacement?

If your furnace is making any of the above noises, it’s a sign that you must have it repaired or possibly even replaced. This is especially true if your furnace has been in use for 10-15 years, as most units have a lifespan of around 15-20 years.

It’s important to not ignore these unusual sounds and address them promptly to prevent further damage and potential safety hazards. The expert technicians at Jacob Heating & Cooling can evaluate your furnace and make recommendations for repair or replacement based on our findings.

We can complete the repairs as needed or install a new furnace to keep you warm this winter.

What Can I Do If My Fuance Stops Working While It’s Cold Outside?

If your furnace stops working during the winter, it’s crucial to have it fixed or replaced as soon as possible. The last thing you want is for your home to be without heat when temperatures are freezing outside.

While waiting to have it fixed or replaced, you can keep your home comfortable by dressing in warm layers, using space heaters, and closing off rooms that aren’t being used.

If you find that your furnace isn’t functioning in the middle of winter, call Jacob Heating & Cooling for our 24/7 Emergency services.

How do I Choose a New Furnace?

When it’s time to replace your furnace, there are a few factors to consider. These include the type of fuel you want to use (natural gas, propane, or electric), the size of the furnace needed for your home, and energy efficiency ratings.

Choosing a reputable HVAC company like Jacob Heating & Cooling for installation services is also important, as improper installation can lead to future issues and inefficiency. We can evaluate your needs and help you find the right furnace to suit your home and your budget.
