HVAC source, composition and distribution system

---

The components of most heating and air-conditioning systems in California have a design-life ranging from ten to twenty years, depending on the climate zone and the extent of their use, but can fail prematurely with poor maintenance. Inspectors test and evaluate them in accordance with the standards of practice, which means that they do NOT dismantle any of the following concealed components: heat exchangers, also known as the fireboxes or combustion chambers, electronic air-cleaners, humidifiers, and in-line duct motors or dampers. Similarly, they do not pressure-test components, and will not reverse the cycle on a heat pump if doing so might damage a coil. However, from the point of view of safety, you need to be aware that even the most modern fossil-fuel-burning systems can produce carbon monoxide, which in a sealed or poorly ventilated room can result in sickness, debilitating injury, and even death. Therefore, it is essential that any recommendation that is made for service or a second opinion be performed by a specialist, who might reveal additional defects or recommend some upgrades that could affect your evaluation of the system(s)

Heating.

 The inspector shall inspect:

the heating system, using normal operating controls. 

 The inspector shall describe:

the location of the thermostat for the heating system; 

the energy source; and

the heating method. 

 The inspector shall report as in need of correction:

any heating system that did not operate; and

if the heating system was deemed inaccessible.

Cooling 

 The inspector shall inspect:

the cooling system using normal operating controls 

 The inspector shall describe:

the location of the thermostat for the cooling system; and 

the cooling method.

 The inspector shall report as in need of correction:

any cooling system that did not operate; and

if the cooling system was deemed inaccessible.
