Caution is always advised around mechanical and electrical equipment including the air handler. Turn the power off before removing any panels.
Air Handlers - An air handler is usually located in the garage, a closet, or in the attic (unless you have a package unit then the air handler is incorporated into one system). It is essential to any AC unit and heating forced air system. All AC units need an air handler or way to move air. It can be a part of your furnace and houses the evaporator coils, the blower motor, and some HVAC controls. It can be an up-flow, downflow, or horizontal flow AHU (air handling unit). (more…)

Trane Air Source Heat Pump Condenser
Heat Pump Types - There are different types of heat pumps available on the market today. A heat pump is an air conditioning unit that cools when the temperature is hot and heats when it is cold. There are many different types of these heat pump systems available. There is the geothermal heat pump. It can either utilize a series of closed-loop water pipes buried in the ground or other methods of heat exchange. This process removes or absorbs heat for heating and cooling.
Air source heat pumps can be configured differently. One type of air source heating will utilize electric heating for backup heating while another may use a gas furnace for backup heating. These types of systems can also be split systems or package units and nearly all share a similar heat pump sequence of operation. A description of the various types of systems and how they work is below in this article on heat pump types. These systems utilize similar heat pump components but differ in how the heat pump works.
