A furnace closet houses an HVAC system, which stands for Heating, Ventilation, and Air Conditioning system. However, it can be a little bothersome because it generates noise, sometimes at a very high level.

According to a National Institute of Health research, noise is the second most prevalent environmental pollutant affecting human health. It can cause sleep disruption, cardiac difficulties, and even hearing loss.

As a result, if you live in an apartment and your furnace closet is near your bedroom or any other room where you spend the majority of your time, you should soundproof it as soon as possible.

But how do you do that? That is why you should read this post. Because I detailed 7 simple ways to soundproof a furnace closet in my article. Also included is a step-by-step procedure for doing this appropriately.

Is it going to be costly?
Because this topic is frequently asked, you must invest in soundproofing, although it is not prohibitively expensive.

We discussed some cost-effective methods, and even the materials we shared are reasonably priced, simple to install, and provide the best outcomes.

Overall, you don’t have to spend a lot of money to obtain the greatest outcomes.

Which of these 7 methods for soundproofing a furnace closet is the best?
Let us begin with the seven simplest methods for soundproofing a furnace closet that anyone can try.

1. Increase the amount of mass near the machine.
It is the fundamental principle of soundproofing. The more bulk you add, the more noise it absorbs, allowing you to create a soundproof furnace closet. Adding plywood, sheets, or any other mass will no longer work.
You’ll need a sound-absorbing substance. Heavy carpets, garments, and other inexpensive choices are available. However, I recommend that you purchase acoustic panels or soundproofing blocks.

An acoustic panel is made of foam and comes in a variety of forms and sizes. It’s simple to set up, but the sheets must be placed precisely. Stick them with a suitable glue or place them in those awkward spaces. It is the most effective.

Soundproofing blocks are a comparable material that is specifically developed to absorb noises and provide you with the finest experience possible. Sound blockers can even be placed on the floor.

These materials are inexpensive.
They provide the best experience and are simple to set up.
You can buy them at your local store or get them online.
Using this one strategy, however, does not ensure the optimum experience. Even acoustic panels are not impervious to subsequent noise. You must also take another measure from this list.

2. Cover Walls with Drywall
Drywall is an amazing substance that is ideal for soundproofing. Even professionals encourage using them, although they can be costly.
Drywall is used to build ceilings and walls. It functions as an additional layer between your machine and the closet walls, absorbing noises and providing the finest experience that other materials cannot.

You must obtain drywall sheets from the market, cut them to size, and install them on the walls near the closet.

You can either build a wooden frame to hold the drywall in place (with nails) or simply stick it in place with an adhesive. It works in both scenarios.
It is the most effective method for entirely soundproofing the closet.
It’s a little pricey, but it’s worth the investment.
You can do it yourself. There is no need for professional assistance.
There are certain drawbacks to using drywall, such as the necessity to remove the furnace, the time and work required, and the requirement to invest in hardware such as the wooden frame, adhesives, and nails.

3. Noise reduction The Grounds
Making the floor thicker aids in soundproofing, but it also aids in vibration reduction.

A sturdy floor is essential since insulating the walls will help reduce noise. But I’m sure the vibrations and grumbling sound are bothersome.

It is not expensive to make the floor thick. You must utilise as many carpets as possible. Install them properly on the floor to absorb most vibrations, and you’ll have a soundproofed environment.

Even rugs will block the bottom of the door, allowing a lot of noise in. Make certain that you get the thickest carpeting available.
If you have the extra cash, we recommend purchasing anti-vibration pads. You’ve probably seen these washing machine vibration-reducing pads. For the greatest experience, install large anti-vibration pads on your machine.
Covering the floor will complete half of the work.
Anti-vibration carpets help to reduce noise and vibrations.
These things are inexpensive but produce the best effects.
If you wish to install the anti-vibration pads, you will have to remove the machine first and then install the pads. You will require outside assistance.

4. Use Vibration Mounts
A vibration mount, like anti-vibration pads, helps to reduce vibrations, however they are utilised on walls rather than the floor.
These are rubber-covered metal items with a spring connected. You can easily mount them on the wall next to the machine.

These mounts will absorb all vibrations, providing the greatest vibration-proof environment and preventing grumbling noise.

The more mounts you use, the better your experience will be. They are inexpensive and simple to install. To address the problem, you must attach them to the wall with iron nails and touch the machine.

The vibration mounts protect you from the rumbling noise.
The gadget greatly aids in soundproofing.
You may easily buy them in a local store or get them online for a reduced price.
Professionals advocate vibration mounts since they improve the overall experience. They received numerous advantages!
5. Increase the weight of the door
A lightweight door will undoubtedly allow a lot of noise to get through, rendering all of your soundproofing efforts futile. With all other ways, ensure that the door is heavy and effectively prevents noises.

The various methods for producing the thick door include
Install an additional sheet of plywood on the rear of your door. This will serve the purpose and will have no effect on the design or finish of your door.
Cover the back of your door with acoustic panels. They are made of foam, which is the most cost-effective material for noise reduction.
Wrap thick clothes or foam around the back of your door. It is the least expensive choice, but it may not produce the best results.
A heavier door is essential for soundproofing and plays a key role in the process. It is hard to get a soundproof furnace closet without a thicker door.

Even so, it does not necessitate a significant amount of labour or investment. You’ll need some adhesive and some nails for hardware, but you can easily DIY soundproofing your door.

6. Examine for any holes
A furnace closet is a room that houses a machine, and builders must cut holes for cables to pass through.

Sometimes they leave larger holes that you don’t see but are a substantial source of noise in the room.

You must inspect the room for those holes and any other dents. Use cement, a high-quality adhesive, or cloth to secure them. To get the greatest experience, please pack them tightly.
It may not seem like much, yet it has a significant influence.

A single hole can undo all of your soundproofing efforts.
If the hole is not correctly packed, a lot of noise will pass through.
It is fairly simple to fill in these gaps.
It may be more difficult to detect any holes in those tight areas, but you must look. These few changes make a significant difference.
7. Fill Any and All Gaps
This is our final step for soundproofing the furnace closet. Filling gaps is similar to filling holes, but not the same.

Examine the top and bottom of the door, the gap between the door flaps, and the sealing for any cracks.

Carpenters typically allow areas for smoothness at the top and bottom of the door. When the door is closed, you must ensure that it is tightly packed. Use carpet on the floor and more wood on top.
If you only have one door, that’s fantastic, but if you have two door flaps that close on each other, make sure they’re closing tightly. If not, apply rubbers to the corners to ensure adequate sealing.
To improve the entire experience, look for cracks in the wall and fill them with a harder material.
It’s easy, and sealing the room properly will offer you the best results. Make certain that you completely inspect the furnace closet room.

Other Options for Soundproofing a Furnace Closet
Before we dive into the soundproofing material, let’s look at some simple alternatives. You don’t even need to spend in soundproofing if you can take any of these steps.

1. Redesigning
Your furnace closet is a large machine with an engine, belts, numerous nuts and bolts, and many iron and steel parts.

These materials become loose over time and begin to make noise. You may control the noise to a large extent by oiling, lubricating, and tightening the loose parts.

Even minor maintenance will extend the life of your machine and keep you from hearing unpleasant noises.
Furthermore, soundproofing takes time and effort. Starting with this easy step may provide you with numerous benefits in the subsequent phase.

2. Move It to a Different Location
Most people prefer to use these large machines in their garden, where the noise is dispersed throughout the environment and you can scarcely hear anything.

If you are creating your own home, always include an HVAC system in the backyard. If you live in an apartment, though, you have no choice. You might refer to the soundproofing process explained in this article for that.

Even for maximum soundproofing, you must remove the furnace, and it would be preferable if you could relocate the HVAC equipment to your garden.

3. Employ A Mechanic
If your furnace closet is creating too much noise, even the greatest soundproofing solutions will not be effective. In such instances, we recommend that you call a mechanic to fix your furnace closet.

He’ll tie up all the loose threads so your furnace closet makes little to no noise. Don’t worry if you continue to have problems; we may take further soundproofing measures to ensure that you have a soundproof atmosphere.
We want you to take these precautions before investing time and money in soundproofing. It’s as though half of your work has already been completed.
