A good furnace should provide heat while staying out of sight, out of mind. Therefore, if your furnace is making noises, there is a problem. Read on for Andersen’s common causes and solutions for a noisy furnace.

Rattling noises

If you notice what sounds like rattling or shaking coming from your furnace, chances are there are some loose components. Fortunately, this is a relatively simple fix. Schedule furnace maintenance to make sure all screws and fasteners are properly tightened so your equipment doesn’t rattle.

Scraping, banging sounds in Charlotte

Some homeowners report hearing loud scraping or banging noises coming from their furnace or ductwork. If this happens to you, it’s time to schedule furnace repair from Andersen Heating & Cooling. These noises can indicate that you have a loose or broken blower wheel. This can cause significant damage to your HVAC system. Turn off your furnace and call Andersen if you hear scraping noises.

Noisy furnace whistling

We also commonly hear complaints of whistling or high-pitched squealing noises from the furnace. This usually can be attributed to poor airflow throughout the ductwork. The first step here is to change your air filter. Fresh air filters provide countless benefits for HVAC systems, including quieter operation. If this doesn’t help, you may have some small cracks or holes in your ductwork. These need to be sealed by a professional.

Popping or tapping noises

Finally, our heat pump customers often report a constant popping or tapping noise during fall and winter. What they’re hearing is actually the sound of leaking refrigerant. Refrigerant leaks can be costly and decrease your heat pump’s efficiency. Refrigerant must be recharged, and the leak itself must be sealed and repaired.

No matter what kinds of sounds your furnace or heat pump makes, there is a solution. If you have a noisy furnace, call Andersen Heating & Cooling today! Our HVAC experts will make sure your heat is as silent as it is comfortable this fall and winter.
