HeatingTipsIs there something wrong with my furnace?

January 5, 2023by Dev

A high-quality heater should remain out of the way, out of sight, and out of mind. If you have noticed that your furnace is producing noise, here are a few probable causes and solutions.

Scraping noises

Some people hear thumping or scraping noises coming from their furnace or ductwork. If you think you might experience this problem, then that’s the right moment to schedule your furnace repair with Andersen Heating & Cooling. These noises can indicate that you have a loose blower wheel, which might damage your HVAC. Turn off the furnace and call Andersen if you hear these noises regularly.

If you hear rattling or shaking coming from your furnace, it’s probably due to loose parts. Although this is usually an easy fix, schedule furnace maintenance to inspect all screws and fasteners to ensure they’re properly tightened so there is no rattling.


We also commonly hear reports of whistling or high-pitched squealing noises emanating from the furnace system. This usually is due to the ducts having an issue. The first step is to change your air filter. Changing your air filter will have countless benefits for HVAC systems, including quieter operation. If this doesn’t make a difference, you could have some small splits in your system.

Popping and Tapping

Lastly some people usually hear a popping or tapping sound from the heat pump during the fall and winter. What they’re hearing is refrigerant leaking out of it. Action is needed to fix the refrigerant leak, and repairs must be made to the leaking component. If left unchecked then the costs can increase due to the expensive price of most refrigerants.

If you suspect your system is not working properly contact the local professionals at Andersen Heating & Cooling
