Noisy AC in Peoria, IL

As a property owner, you rely on heating and cooling systems to keep your building comfortable in cold and hot weather. However, some units make a lot of noise while in operation that can disturb sensitive individuals like light sleepers. Luckily, you can minimize these disruptions by soundproofing your HVAC unit. This article will discuss the different ways to soundproof your noisy HVAC system effectively.

1. Use a Sound-Absorbing Blanket

A soundproof blanket or sound curtain comes in handy when you want to reduce the noise coming from your HVAC unit. Sound blankets are easy to install, inexpensive, and have amazing noise-reduction capabilities. Many sound curtains contain vinyl and fiberglass materials which are excellent sound absorbers. Although they won’t provide a 100% soundproof solution, you’ll notice a significant difference in noise reduction around the compressor.

Even better, the sound-absorbing blanket doesn’t interfere with the proper working of the HVAC system. These blankets encourage airflow within the unit, ensuring it doesn’t overheat. They are also not flashy, big, or bulky, so they won’t interfere with the aesthetics of your home.

2. Enclose the HVAC Unit

Another solution is providing an additional buffer against HVAC noise. You can build enclosures like a wooden fence or plants such as bushy shrubs. Other barriers like a vine lattice, aluminum slats, lawn ornaments, flower planter boxes, and vinyl are also effective in soundproofing noise around the unit. Remember to choose materials that aren’t prone to sound reverberation.

When building these enclosures, leave some room between them and the HVAC system. The extra space provides room for air circulation to prevent overheating. Also, make sure the barrier is easy to remove or move in case a technician wants to access the unit.

3. Use Flexible Ductwork Where Possible

Generally, sound travels in a straight line. Therefore, you can reduce sound transmission significantly by introducing curves and bends along its path. And because flexible ducts bend easily, they can minimize the sound leaking from the unit’s vents. Consider installing flexible ductwork in areas prone to noise activity.

However, you should only install flexible ducts where necessary. These ducts have small breaks that easily leak sound, reducing their effectiveness. Install them in quieter areas to prevent sound from traveling in them. Also, use high-quality flex ducts to reduce the chances of this problem.

4. Place the Unit on a Suitable Surface

The surface where you’ve placed your heating and cooling unit can make a significant difference in sound. Most noise originates from vibration due to an unsteady surface or unsteady contact with the ground or wall. Even a slight rattling while the HVAC unit is in operation can cause a considerable annoyance.

Eliminate these noises by positioning or attaching your unit properly on steadier ground. Use some foam to even out the surface. This will position your HVAC unit properly, which reduces vibration because it will not rock around too much.

5. Install Duct Liners

Installing duct liners on your HVAC system is another easy and cheap method of soundproofing your unit. Duct liners consist of absorbent materials that easily absorb the noise resulting from vibration in the inner walls of the vents. These liners are also double-sided to prevent the wool fibers from getting blown into the house.

An HVAC technician installs the duct liners on the air vents’ inside walls. This method also helps reduce your energy bills because it insulates the ventilation system.

6. Change Your Location

If you have the opportunity to choose a suitable location for your HVAC unit, it’s a smart way of keeping away the noise. Consult those around the house or business premises to help you pick out the ideal new location. Avoid areas that can be problematic for many people, such as near offices, bedrooms, quiet rooms, living rooms, neighbors’ households, and where people spend most of their time. Also, don’t place your unit near narrow hallways to avoid sound amplification and unwanted noise.

The back of your building can be a strategic position to install your HVAC unit. You can also ask for recommendations from an HVAC professional on the best location to set it up. This strategy can save you money because you won’t have to invest in other sound-reduction solutions.
