Under normal working conditions, your HVAC unit in Excelsior Springs, MO should not produce annoying sounds. Loud sounds signal there could be an issue with your system. However, older units tend to create more noise even when they’re working well, in which case you might want to consider soundproofing your air conditioner.

Choose a Quieter Model

First and foremost, if you have an older air conditioner, the best way to reduce the amount of noise is by replacing it outright. If your unit breaks down often, it can also help save you some money in the long run. In the case that it’s newer, it might actually be too big for your home, which can lead to increased noise. You can also contact a professional, like us at Valley Mechanical LLC, to inspect your air conditioner and give you advice on what steps to take toward finding a quieter one.

Use Acoustic AC Blanket

Of course, replacing an air conditioner entirely isn’t in everyone’s budget. Don’t worry, though — you still have options! Some manufacturers actually create soundproofing blankets that are meant specifically for use with air conditioners. These often go inside of the main air conditioning unit and can help insulate it, preventing a good 30-50% of the noise from making its way into your home. Moreover, the insulation helps maintain consistent temperatures and deter condensation on the coils.

Install Duct Liners

Sometimes, air conditioners themselves aren’t the source of distracting sounds; it might be your home’s ductwork. In that case, have a professional make sure that your ducts are in good condition and fastened properly. You might also want to consider investing in duct liners. These materials help reduce unnecessary noises throughout your home’s ductwork, hinder microbial growth, and can even reduce energy losses in your system. In turn, you can get better indoor air quality, more consistent indoor temperatures, and lower energy bills.

Seek Out Professionals

Most HVAC units use sound-dampening technology to minimize the amount of noise from the equipment. However, if your unit is producing more noise than necessary, there are a variety of possible causes, including:

  • Dirty condenser, ducts, or air filters
  • Damaged or broken refrigerant
  • Frozen coils
  • Blower motor failure
  • Low lubricant levels
  • Electrical failure

It can be hard to determine the cause of an HVAC noise unless you are a professional. Different sounds signal varied issues and causes of the noise. Therefore, before investing too much in soundproofing, seek expert advice for accurate diagnosis and correction of the problem.


Like any other equipment, your HVAC unit produces some sound during operation. However, the noise should not disturb your peace or interfere with your focus on your daily routine.
