HVAC Contractor more HVAC definitions. HVAC is an abbreviation for Heating, Ventilation and Air Conditioning. HVAC Contractors specialize in the installation and maintenance of furnaces, boilers, heat pumps and central air conditioners. However, in addition to installing and maintaining HVAC equipment, HVAC contractors typically help consumers decide which equipment to purchase. This makes the HVAC market somewhat different from the market for other expensive consumer products.

HVAC Duct, A Homeowners Guide... Your hvac duct system is the heart of your home's heating and cooling system. Without a healthy system you could be wasting a lot of money. Like the human body, if the heart isn't healthy you are in trouble. A duct system provides a controlled path for air flow throughout the home.he two main types of supply systems are extended plenum and central plenum. A central plenum system is a system where all of the branch ducts start at the same location called a plenum. The extended plenum system consists of a supply air plenum which is connected to the outlet of the hvac equipment.
