How to Reduce Noise Levels Before, During, and After AC Installation

One of the most overlooked factors when selecting a unit for your AC installation project is the noise levels of the air conditioner. Check on this level, which is readily available on the unit's specifications sheet. The noise levels should be clearly stated on the specification sheets for both the indoor and outdoor units.

Where Is the Noise Coming From?

Noise will typically come from the outdoor condenser unit and the indoor evaporator. The condenser consists of a compressor that releases most of the sound pressure. Over time, the noise may worsen due to the wearing off of the vibration pads used for mounting the compressor to your unit's metal casing. 

Wearing off the motor and other components will have the same effect. Again, any imbalances in the fan, be it worn out fan motor bearings or leaves and other materials blocking the fan blades, can lead to it rotating noisily. 

Similarly, so much of the noise in the evaporator comes from the fan. Dirt, dust, and other material may collect on the fan blades over time and block their movement, causing noisy operation. Damaged fan motor bearings can also cause the same problem.

Minimizing Noise Levels Before AC Installation

Some AC units are less noisy than others. Check against the specification sheet of your options to find a quiet air conditioner. 

However, one thing to keep in mind is that air conditioners with a higher cooling capacity tend to be noisier. If your AC installation delivers a lower cooling capacity, you can realistically expect it to be quieter.

Minimizing Sound During AC Installation

In addition to the AC installation itself, you can talk to the HVAC experts about putting in place a few measures to reduce noise. Installing a sound blanket around the condenser unit is always highly effective. The blanket will deliver excellent sound-canceling without compromising your unit's performance. 

Choosing a good location for the AC installation will also help reduce noise. Keep the outdoor unit further away from your home. For the indoor unit, you want it away from the hallway and other spaces that would otherwise reverberate the sound.

Minimizing Noise After AC Installation

As already highlighted, blockages and wear and tear can cause your air conditioner to operate noisily. Regular maintenance, including cleaning the evaporator coils and vents and replacing the air filters, will ensure your system runs smoothly and quietly. 

Noise of any form is always undesirable. Choose the right unit, and with the best practices before and after your AC installation, you won't have to worry about a noisy air conditioner. For more information, reach out to a service such as Mid Atlantic Mechanical and Repair, LLC.

About Me
what services can an HVAC technician do for you

What can your HVAC technician do for you? Some HVAC contractors perform tasks beyond the heating and cooling system work that they do for you. In fact, my HVAC technician does plumbing and even some electrical work in my home. I had no idea that the company offered this type of service until he made a few suggestions about improving the plumbing system in my home as he inspected my HVAC system to get it ready for winter. Find out what your HVAC contractor can do for your home here on my blog. When you've reached the end, you will know very well what you can ask of your technician and avoid contacting a second contractor.
