OC: Introduction to Inspecting Cooling Systems

Keeping a house cool during hot summer days is vital to the comfort of a house’s occupants. This may be accomplished by using one of the many types of available cooling systems, each of which uses a refrigerant or water to transfer the heat from the indoor air to the outdoors. A cooling system may be combined with a heating system or may be a separate system. These systems may be mounted in attics, closets, windows, or through exterior walls.
This Unit focuses on the systems that are used most frequently in today’s homes. These include central air conditioning systems, heat pumps, window and through-wall units, and evaporative coolers.
