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.

Will my new furnace work differently than my old one?

When replacing the outdoor unit, should the indoor unit also be replaced?

How can I confirm the model and serial numbers for my heating system?
