Are Mini Split Heat Pumps Noisy? (A Comprehensive Guide 2024)

Are you considering investing in a mini split heat pump, but wondering whether they will be too noisy? You're not alone. Many homeowners are skeptical of the noise level that their new heating and cooling system will produce. In this guide, we'll address the question of whether mini split heat pumps are noisy and provide you with all the information you need to make an informed decision.

What is a Mini Split Heat Pump?

First, let's start with the basics. A mini split heat pump is a type of heating and cooling system. It is designed to provide zoned heating and cooling to individual rooms or spaces in a home. Unlike traditional HVAC systems, which use ductwork to distribute air throughout a building, mini split heat pumps use individual units installed directly in the rooms they serve.

Mini split heat pumps consist of an outdoor condenser unit and one or more indoor air handlers. The indoor units are connected to the outdoor unit through a small conduit that contains refrigerant lines, a power cable, and a condensate drain line. This allows the system to distribute heating or cooling throughout a home without the need for ductwork.

Are Mini Split Heat Pumps Noisy?

The short answer is no. Mini split heat pumps are not noisy. In fact, they are one of the quietest heating and cooling systems available today. The noise level produced by a mini split heat pump is typically around 20-25 decibels (dB), which is about the same level as a whisper.

To put this in perspective, a normal conversation produces about 60 dB of noise, while a vacuum cleaner produces 70-80 dB. Even a library is typically around 40 dB, making mini split heat pumps significantly quieter than most indoor environments.

 What Causes Noise in Mini Split Heat Pumps?

While mini split heat pumps are generally quiet, there are a few factors that can affect noise level :

  1. Outdoor Unit Noise: While the indoor units of mini split heat pumps are typically very quiet, the outdoor unit can produce some noise. This is because the outdoor unit contains a compressor and fan that can create some sound. However, most models available today are designed to operate at a low noise level, typically around 50 dB, which is still significantly quieter than traditional HVAC systems.
  1. Placement of Indoor Unit: The placement of the indoor unit can also affect noise level. If the unit is installed too close to a wall or ceiling, it can create an echo effect that amplifies sound. Additionally, if the unit is installed in a room with high ceilings or hard surfaces, it can create more echo and make the unit seem louder.
  1. Type of Indoor Unit: There are different types of indoor units available for mini split heat pumps, including wall-mounted, ceiling-mounted, and floor-mounted units. Wall-mounted units are typically the quietest of the three, while ceiling-mounted units can produce a bit more noise due to their location near the ceiling.

How to Choose a Quiet Mini Split Heat Pump

If you're looking for the quietest mini split heat pump possible, there are a few things you can do :

  1. Choose a Quiet Model: When shopping for a mini split heat pump, look for models that are designed to operate at a low noise level. Many manufacturers will provide noise level ratings for their systems, so be sure to check these ratings when making your decision. We highly recommend the models from Sharp, Haxxair and Gree, which are some of the most silent on the market!
  1. Consider Placement: When installing your mini split heat pump, be sure to consider the placement of both the indoor and outdoor units. Avoid installing the indoor unit too close to walls or ceilings, and choose a location for the outdoor unit that won't be directly next to a bedroom or living space.
  1. Purchase a Sound Barrier: If you're still concerned about noise level, consider purchasing a sound barrier. Sound barriers are designed to absorb and reduce sound, and can be installed around the indoor or outdoor unit to further reduce noise.

Final Thoughts

In conclusion, mini split heat pumps are generally very quiet and should not cause any significant noise issues in your home. With proper installation and placement, you should be able to enjoy comfortable heating and cooling without even noticing that the system is running. If you're concerned about the noise level of your mini split heat pump, be sure to choose a quiet model and consider additional sound-reducing measures. Do not hesitate to contact us for any question, advice or 100% free on-site estimate!
