Equipment Types Explained

The Valley runs on a wider mix of equipment than most cities: split systems in the side yard, packaged units on the roof, heat pumps doing double duty, ductless heads in the casita, and the occasional evaporative cooler still earning its keep in May. Each type fails in its own way and is serviced in its own way.

These pages explain each one plainly: what the parts are, how the system moves heat, where it is typically installed in Phoenix homes, what tends to break, and how long it realistically lasts in a climate that runs equipment three thousand hours a summer. Read the page for your system before you read the page for your problem.
