Chapter 8:                      Heating and Cooling Systems

This chapter discusses safety and energy-efficiency improve­ments to heating and cooling systems. It is divided into these main sections.

1.      Essential combustion-safety testing

2.      Heating-system replacement:

3.      Servicing gas and oil heating systems

4.      Combustion venting

5.      Heating distribution systems

6.      Air-conditioning systems

The SWS requires that weatherization agencies perform a com­bustion-safety evaluation as part of each weatherization work scope. This evaluation is the chapter’s first topic. The chapters other topics are procedures and requirements related to cost-effective ECMs, such as tune-ups and equipment replacement.
