Quick and easy checks on indoor units (ACHPI24)

November 2011

Improving system operation - quick and easy checks on indoor units.  The competent technician will carry out cursory system checks, some by ‘sight, sound and smell’ based on their technical knowledge of the system, to make a reasonable assessment of correct system operation. This can help to evaluate whether to proceed with more detailed diagnostics on performance. This bulletin outlines some of these quick and easy checks which can be carried out focusing on the indoor unit. It provides some helpful pointers based on practical experience which could be the basis of your own checklist when considering maintenance requirements or energy inspections.
