A professional HVAC system makes all the difference in ensuring your heating, ventilation and air conditioning is up to code and running at optimal comfort levels, as well as minimizing the chance of system failure that can lead to serious injury.

What is HVAC?

HVAC stands for Heating, Ventilation and Air Conditioning.
It is a combination of systems used to move air between indoors and outdoors, as well as the heating and cooling functions. This is the system that will keep your employees and customers warm and cozy in the winter, and keep them cool and refreshed in the summer. It is also crucial to the filtration of indoor air for optimal health and humidity levels.

But how does it work and do you really need it?

HVAC: more than a temperature control system
While the main function of an HVAC system is to warm or cool, it also serves to improve the indoor air quality of a space for the comfort and health of the occupants.

How does HVAC work?

The most common HVAC system is a combination of central heating and air conditioning systems that utilize a single blower to circulate air either via ducts or a ductless system for different rooms and zones. It is also possible that each component is separate, in the case of a radiant system combined with window air conditioning units.

All HVAC systems are comprised of the same basic elements:

Ventilation: a source of fresh air intake (either outdoors or within the building). This can happen in two ways.

  1. Natural Ventilation is most common and refers to the way air typically moves in and out through windows, doors, vents and other openings. This exchange of air is necessary to replenish oxygen, as well as to remove odors, carbon dioxide, unpleasant odors, and excessive moisture.
  2. Mechanical Ventilation uses a mechanical system to move air in and out. Modern construction is creating increasingly tighter seals, so ventilation is becoming an increasingly important component in HVAC systems. The unit draws air in through filters to remove dirt, dust, allergens and other particles. The new, “fresh” air is then either sent to be heated or cooled for optimal comfort levels and have excess humidity removed. For central systems, this means moving through a network of ducts and registers to different rooms. For other systems, this usually means being directed right into the space.
