Gas Furnaces

If you are in the market for a natural gas or propane furnace, don't overlook residential furnaces. Even though these products are designed for a different market, they have a lot to offer commercial buildings. For example:

  • Residential furnaces are manufactured in much larger quantities than commercial furnaces. That makes them relatively inexpensive and readily available with a wide variety of options.
  • Because they are available in relatively small sizes, they can accommodate nearly any zoning scheme.
  • The most efficient residential furnaces are far more efficient than their commercial market counterparts.

For these reasons, residential furnaces (Figure 1) are frequently superior to commercial furnaces for many commercial building applications.
