TRAINING HEATING VENTILATION & AIR CONDITIONING

TRAINING HEATING VENTILATION

TRAINING AIR CONDITIONING

DESCRIPTION

Heating, ventilation, and air Conditioning (HVAC) is based on the principles of thermodynamics, fluid mechanics, and heat transfer. The invention of the components of HVAC systems went hand-in-hand with the industrial revolution, and new methods of modernization, higher efficiency, and system control are constantly introduced by companies and inventors all over the world.

One of the most important features in any home is the air conditioning and heating system, also called the HVAC system. People do not usually think about their furnace or air conditioner until that equipment stops working. Then, fixing them become the most important thing on the “to do” list.

An HVAC estimator handles the instillation of heating, air conditioning, refrigeration and ventilation units in homes and businesses. HVAC estimators make sure the units will fit into designated areas — or even designate the area where the units will go themselves — and ensure technicians are provided with the proper tools and direction to install the units. Most HVAC estimators must be trained and work as technicians first.
