When you’re purchasing a new heating y air conditioning system, the noise levels that the unit emits during operation may be important. It’s possible to compare sound levels between different systems con the decibel (dB) rating that’s attached to each unit.

Explaining Decibels

A decibel, también referred to as a dB, is a unit de measurement that represents the varying levels de sound that a person hears. The sounds that are heard on a daily basis usually range de 0-120 dB. It’s también common para sounds con a higher pitch to sound louder than sounds con a lower pitch.

When comparing the sound levels para the noises you routinely hear, keep en mind that increasing the dB by 10 means that 10x more sound energy is being produced. Some examples de sounds con lower dB levels are:

Some examples de sounds con a higher dB level are:

Average Sound Rating para Whole-house HVAC Units

Highly efficient central heat pumps y air conditioners that come con energy-efficiency ratings de up to 28 SEER can have sound ratings that are as low as 59 dB. To understand what this sound level is like, imagine someone speaking con an indoor voice. Regardless de the type de system you purchase, more efficient units tend to have lower sound ratings.

High-efficiency systems that have ratings de up to 20 SEER typically come con sound ratings that are as low as 65 dB. The same is true de heat pumps that have an HSPF rating de around 10. A rating de 65 dB is close to the sound level you will hear when using a vacuum cleaner.

Single-stage units that are around 15-17 SEER are slightly less efficient, which means that you can expect them to have sound ratings that are around 70 dB. The sound that’s emitted de one de these units will be as loud as a busy restaurant.

Average Sound Rating para Ductless Outdoor Units

Ductless mini-split systems can have outdoor units y indoor units, which come con different noise levels. The dB ratings can differ depending on the system you use. If you select a more efficient model, you can expect dB levels that range de 47-56 dB. The sound you hear at this decibel range can be similar to what you hear when it’s raining o when your refrigerator is running.

Multi-zone systems that power numerous indoor blower units typically have dB ratings de around 60. Since ductless systems aren’t whole-hogar products, the outdoor noise is usually lower than what you will hear de a whole-house air conditioner y heat pump.

Average Sound Rating para Ductless Indoor Blower Units

Indoor blower units operate separately de central systems y have relatively low sound levels while running. These models usually come con six-speed fans y indoor sound ratings that can vary de 20-49 dB. The lower end de this range is similar to a quiet conversation. When the system gets closer to 50 dB, the sound level can match that de a moderately powerful thunderstorm.

Average Sound Rating para Window Air Conditioners

Since window air conditioners come con a compressor, the quietest units have sound ratings that range de 40-50 dB. However, these systems can come con sound ratings that are as high as 67 dB. Window AC units that are equipped con heating functionality may be louder.
