Types of AC Units 

Our knowledge of air conditioning units is expansive, including systems such as:


A ductless mini-split cooling system doesn’t require ductwork because it has an A/C unit outside that connects to units in the home. These units then distribute the cooled air being pushed into them from outside. You can control the temperature of your entire home/business or just one room with the air handlers located in specific areas.  


Central air systems are the most commonly used in the U.S. This system takes cool air and circulates it through a system of supply ducts and return registers located in walls, floors, and ceilings. 

Heat Pumps 

A heat pump is a type of split system that utilizes the functions of both heating and cooling in the home.  During the summer months, it provides cool air to flow throughout your house and during the winter months, it supplies warm air to keep you comfortable in the chilly weather.
