HVAC Services – Do You Hear Noises
Noisy heating ducts can start out as a minor irritation and quickly grow to be a major nuisance, and this is a common problem. For those who are hearing rattling and other noises and are wondering how to fix a noisy HVAC return grille, there are a few items that can be checked and fixed for quieter operation.

Check Both the Internal and External
Heating, air, and ventilation ducts not only carry heated and cooled air throughout the house, but they also carry an abundant amount of noise. These noises often take the form of a whining, buzzing, or vibrating sound, in addition to a howling noise. Some units also produce a distinctive banging or rattling sound. When this happens, it could be due to how the internal and external parts are connected. When determining how to fix a noisy HVAC return grill, ensure the internal ducts are connected independently to the external system.
Add Padding and Insulation
Any noise that travels through the heating ducts frequently originates in the air handler. This metal air box contains parts that often will vibrate noisily from normal motor operation. Using thick insulation and some padding around the air handlers will not only muffle the noise created by the internal parts but will also reduce the amount of reverberation sent into the duct vents. When considering how to fix a noisy HVAC return grille, remember that this insulation will also help control any external noises that may be heard by neighbors and others nearby.
Install Acoustic Insulation
Other sound-absorbing materials can also help to answer the question of how to fix a noisy HVAC return grille, as they can contribute significantly to decreasing the level of noise. Acoustic insulation is specifically designed to soak up noises that emanate from the system, and this sound absorption applied at the source will have the effect of diminishing noises as they travel through the system, making them almost silent by the time they reach the vents. An HVAC tech can ensure this insulation is specially fitted along the lengths of the ducts.
Schedule Regular Cleanings and Maintenance
When most people want to know how to fix a noisy HVAC return grille, they often do not realize that those unpleasant noises coming from their system may be due to a lack of maintenance. Scheduling regular cleanings and maintenance with a certified, professional HVAC technician can keep their system running and performing at peak efficiency. Your HVAC technician will keep all the components in good condition, and ensure none are loose or not fitted together properly, facilitating smooth and quiet operation.
Check the Fan
The fan on the unit attracts a large amount of dirt and dust and can attract even more if you have pets, live in an older house, or during those times of the year when various types of pollen are at high levels. The HVAC system fan must also be scheduled for regular cleaning and maintenance, as a dirty fan can be the source of much of the unit’s noise. Additionally, the fan should be checked to ensure it is the correct size for the system, as a small fan will underperform.
Other tips that have been successfully used to reduce operating noise are to adjust the louvers on the return grille, and to experiment with different types of filters. Overall, the above tips should result in a reduction of noise during the unit’s operation. However, if the problem persists, it could be that your unit is not the proper size for the house, and is running inefficiently. This results in high energy costs, and increased wear and tear on the system. In this case, a certified HVAC tech should be consulted.
