Installation & Repair

Your A/C & heating experts

Anyone who has lived in Arizona knows how important it is to have a properly working cooling system in place. No one likes to suffer through a sweltering hot summer with an inefficient unit, or with uneven cooling throughout the home. At Donley, we are in the comfort business, and will provide you with options when it comes to a repair or a unit replacement.

Since 1976, thousands have relied on our A/C & heating services. Your comfort is our focus, and that includes proper equipment sizing, optimal air distribution, and energy savings. Our experienced technicians and installers specialize in all makes of both rooftop package and split systems.

Package units: A package unit combines an air conditioner and a heater into one single unit on the roof. Many Valley homes were built with rooftop package units. Package units use ductwork to transport air throughout the home.

Split systems: A split system includes an indoor heating unit and an outdoor cooling unit. Split systems use ductwork to transport air throughout the home.

Mini-split systems: A mini-split system doesn’t require ductwork, making it a great solution for rooms that had not been previously cooled or have been added on. They are also useful for home offices, multimedia rooms, and wine cellars.

Heat pumps: A heat pump system provides both heating and cooling. In the summer, it removes heat from the indoor air and releases it outside. In the winter, the process is reversed.

Dual and hybrid systems: A dual and hybrid system combines a heat pump with a backup heating system that utilizes a separate source of fuel. These systems work in all seasons to cool and heat efficiently.

Variable speed compressor cooling systems: A variable speed compressor cooling system continuously circulates air at a lower capacity, rather than cycling on and off. The compressor only runs at the higher speed in extreme times of need.
