Frequently Asked Question

HVAC Systems include furnaces, air conditioners, heat pumps, ducting, thermostats, and other home comfort controls. These system components are responsible for heating and cooling your home.
HVAC Systems are divided into four main types: heating and cooling split systems, hybrid split systems, duct free (mini-slit), and packaged heating and air conditioning systems. These main types come in different sizes and details to fit into your house or place of business.
The primary function of an AC unit is to keep the air cool while an HVAC unit is designed to heat the air and push moisture out through the vents.
HVAC Systems move air. Generally, the HVAC system takes in air, cools or warms it, and then blows it inside your home.
