Where HVAC Technicians Work

HVAC Service Technicians work in and on every kind of building imaginable.  Large buildings have equipment rooms that contain HVAC equipment. Other buildings have equipment on the roof, in the basement or you might be working in or on a walk-in cooler or freezer.  Small or residential equipment might be located in a closet, basement or in the attic.

The H in HVAC

Heating in cold climates is the driving segment of the business.  Heating equipment you might work on includes gas furnaces, gas boilers, electric resistance coils, heat pumps or even geothermal heat pumps.

Heat transfer mediums include air, water, and steam.  These mediums move the heat from the source to the location needed.  Heat distribution systems consist of pipes and ducts to move the air, water or steam to the different parts of the building.

V is Ventilation

Ventilation changes the indoor air and fresh outdoor air.  Ventilation can be used to remove stale air, moisture, odors, smoke, heat, bacteria or airborne contaminates.  A simple system utilizing an open window is defined as Natural Ventilation.  In many buildings natural ventilation is not practical and forced ventilation is utilized.  Forced ventilation air can be filtered and treated.  The amount of fresh air required for ventilation is mandated by building codes.

AC, Air Conditioning

An Air Conditioning system refers to the equipment providing cooling, heating, ventilation and humidity control.  This term not only defines the cooling but includes the total conditioning of the building.  The cooling system removes interior heat and humidity from areas called zones and disposes of the heat on the exterior of the building.  Air conditioning units can be defined as room units and central or whole building units.

R is for Refrigeration

Refrigeration is used to cool products.  Food and perishable items are cooled to prevent bacteria, yeasts and molds from growing.  The refrigeration specialty may include working on freezers, refrigerators, ice skating rinks and industrial processes.
