Frequently asked questions.

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.

Is sound an issue?

The amount of sound generated by a heating or cooling system can have a significant impact on comfort. Inside the home, a low sound level means no sudden blast of air at startup and smooth, vibration-free operation. Outside the home, low sound levels help you keep the peace with your neighbors. This is particularly important, given that many communities have noise ordinances.

What is SilentComfort technology?

Lennox continues to make significant strides in quiet engineering with advances in SilentComfort technology, which includes the most innovative and reliable features available.

Among the latest products of this evolution is the new Dave Lennox Signature Collection XC21 air conditioner and XP19 heat pump. A patent-pending fan design and compressor with vibration isolators, along with a passive sound-dampening fan grill and Hushtone cabinet, make the XC21 and XP19 the most quiet and efficient central air conditioner and heat pump you can buy. 1

Another SilentComfort innovation is the Dave Lennox Signature Collection G71MPP variable-capacity gas furnace - the quietest furnace you can buy2. The G71MPP gas burners are contained within patent-pending sound enclosures, and the cabinet is reinforced with special sound-absorbing insulation to further reduce operating sound.

Thanks to SilentComfort technology, sound is no longer a barrier to home comfort. To learn more about this revolutionary technology, contact Complete Comfort

Why should I zone my house?

A zoning system is designed for the many ways you use your home. Maybe you're caught up in family "thermostat wars?" Or perhaps you have unoccupied areas that do not need conditioning? A Lennox zoning system allows you to divide your home into separate areas, giving you the comfort and control you've always wanted.

The main benefits of residential zoning are:
Comfort

Zoning meets the specific temperature and airflow requirements of one area, without affecting other areas.
Efficiency

A properly designed zoning system can save you hundreds of dollars in energy costs each year.
Control

Zoning divides the home into different areas and comfort into different levels, giving you more choices and control than ever before.
Quiet Performance

When integrated with variable speed and/or two-stage HVAC systems, zoning allows your heating and cooling equipment to deliver peak performance and efficiency without continually operating at peak capacity. Lower speeds mean lower sound levels.
