5 Tips to Preventing a Noisy Wall Furnace 5 Tips to Preventing a Noisy Wall Furnace

Every family uses a furnace for heating the home and it is a common source of noise in the house, so this article lists down a few important and useful tips to preventing a noisy wall furnace. The source of noise in a wall furnace is the fan of the furnace and circulation of hot air through the duct in the home. A wall furnace is a heating device permanently mounted on the wall propelling out the hot air in the surrounding environment through the vents.

Tip 1 – Dedicated Furnace Room

This is the most common tip in the market on preventing the noise from a wall furnace. Build a dedicated furnace room where the furnace is installed and use sound proofing material on the wall to prevent the noise from scattering in other parts of the home. Apply the soundproofing material on the ceilings of furnace room too. The door of the furnace room has to be a solid core door to stop the noisy wall furnace from disturbing the household.

Tip 2 – High Quality Sound Absorbing Materials

The walls, floors and ceilings, all can be made sound proof by using high quality sound absorbing materials. Soundproofing tiles as well as carpeting work well to cut the noise inside the home. This can be custom cut sizes according to the size of rooms. However, remember to avoid the wooden flooring or hard concrete floors as they help spread the noise.

Tip 3 – Check the Duct System for Leakages

The ducts that carry the hot air inside the home carry the noise too. The movement of air inside the duct causes the generation of noise due to vibration. The breaks and leakages in the duct system of the furnace leak the noise out. Carefully check the duct systems at the joints and at lengths to check for leakage points. Use a high quality duct tape to seal the leakage points such as holes and breaks in the duct system to cut noise of air whistling.

Tip 4 – Use Flexible Duct

It is common practice to use flexible duct at the joint of the duct and the furnace. It helps in cutting out the noise created due to vibration of the blower. This vibration travels along with the solid duct, which is not the case with the flexible duct. The flexible ducts are available commercially.

Tip 5 – Padding the Duct

Check the hot air duct system for loosely hanging on the straps. If so, it transfers the noise in the form of vibration. Use a vibration absorbing material between the ducts and straps on which they are hanging on the walls or ceilings. Padding material too is a very good choice to reduce noise from wall furnace. The padding material can be applied around the ducts from outside to prevent the noise. The noise in the ducts is mainly in the form of vibration. Make sure to use a high quality padding material.
