This article series describes how to inspect and repair all types of residential air conditioning systems (A/C systems). Information for home buyers, owners, and home inspectors about A/C or heat pump system problems. Page top image provided courtesy Carson Dunlop Associates. A somewhat simpler schematic of an air conditioning-only system is provided just below. Srpski prevod nad današji stranica [Serbian translation of air conditioning diagnosis and repair articles] This article series describes the basic components of an air conditioning system

and then we discuss how to estimate the rated cooling capacity of an air conditioning system by examining various data tags and components. The limitations of visual inspection of A/C systems are described. We continue to add to and update this text as new details are provided. Detailed information about air conditioning purchase, installation, troubleshooting & repair is provided here - CONTACT us if you can't find something. If your air conditioner or heat pump system is not working, start at LOST COOLING CAPACITY for help in diagnosing and repairing the trouble. Let's introduce the most basic concepts of air conditioning first: Here is a simple explanation of how an air conditioning system works, with enough detail so that it isn't simply magic (the schematic of an air conditioner shown at left is compliments of Carson Dunlop) A detailed list and photos of air conditioner components can be seen at AIR CONDITIONER COMPONENT PARTS.
