Quiet Operation

Is there really a difference between air conditioner and heat pump sound levels?

Most heating and cooling systems manufactured today are quieter than those produced in past years. But there is still significant variance in sound rating ratings among these products.

Lennox designs each air conditioner and heat pump to be as quiet as possible. Through extensive testing, Lennox has come up with many features that, either alone or in combination, make our air conditioners and heat pumps some of the quietest available.

Insulated compressor compartments, discharge mufflers and patented fan designs work to soften the sound of a hard-working, high-efficiency compressor. Top-panel orifices, compressor wrappers and indoor blowers are all designed to further promote smooth, quiet airflow.
