Short for heating, ventilation, and air conditioning, HVAC systems comprise an integral part of our everyday life, from homes to offices. And whether you believe in climate change or not, it’s near impossible to live without an air conditioner in the New Jersey heat. So, dedicated to this somewhat necessity of our daily life, in this article, we’ll be going over all the basic information about these systems, from HVAC heating solutions to HVAC maintenance in NJ; everything.

A Detailed View of HVAC Systems

As their unabbreviated name suggests, HVAC systems are not individual units themselves, but they’re composed of three separate systems. Essentially, these systems are designed to give users complete control over the air quality of the desired space. However, most air quality functionality is installed within only one component, the ventilators. All the rest of the two systems manage is air temperature: one unit for cooling and one unit for heating. The exact breakdown of HVAC components is as follows:

  • The Heating Unit (also known as furnace or boiler).
  • The Ventilation Unit (responsible for maintaining air quality).
  • The Cooling Unit (commonly known as an air conditioner).

The Components of the HVAC System


As a climate control device, HVAC systems must be able to raise the temperature of a place. This seemingly simple task is performed by one of the bulkiest and sturdiest machines in a home or office i.e., the furnace. The furnace is responsible for heating to a specified temperature the water from a reservoir and circulating it into the radiator system. The radiator system then functions to warm up the entire space (home or office) through a process called convectional heat exchange.

These days, furnaces come in three basic types: traditional gas burners, electrical systems, and solar-powered ones. Out of all these systems, the gas ones are the cheapest but most expensive to run, while the solar-powered ones are the most expensive but have the lowest running cost. For HVAC maintenance NJ, gas ones take the most time.


Due to generally favorable domestic air quality, ventilation units are treated as secondary features of HVAC systems. The true shining place of these systems is in the industry sector, where a specific quality of air is required to maintain production standards. This isn’t to say that domestic HVAC systems don’t have ventilation; it is, in fact, integrated into the cooling components.

HVAC Cooling Systems

Air conditioners, as they’re known, are the second component of HVAC systems that are responsible for thermal control. Air conditioners function by lowering the temperature of the cooling pipes, passing air over them, and then circulating the air throughout the room. Modern-day air conditioners come in two types: the exterior compressor and the interior ventilator. The compressor is responsible for cooling the pipes and suctioning in the air, while the ventilator is responsible for circulating it throughout the room.

HVAC Maintenance

Last but not least is system maintenance. The recommended maintenance period for domestic systems is every 4 to 6 months – as for the industrial units, it’s every month or as needed. And that concludes our article on what are HVAC systems.
