A Guide On Commercial HVAC Fundamentals: Key Considerations Before Installation

Posted on

HVACs are important to the commercial sector, this equipment is used to control airflow temperature and quality in buildings. In turn, they guarantee the comfortable accommodation of the premise's occupants. The main components of a functional conditioning system encompass:

How a Commercial HVAC Works

This system primarily facilitates heating, air conditioning, and ventilation in a building. Each of these processes has an independent unit that makes up the HVAC as a whole.


Compressors pressurize refrigerants, which cool down in the condensation coil as a liquid. A blower allows the entry of warm air and releases it over evaporators which changes the liquid refrigerant to a cool gas. The gas refrigerant absorbs heat from the air, thus cooling it effectively.


After adjusting the thermostat, a signal reaches the furnace to begin heating in the burner. The resultant heat in the system heats up the air as it moves through the heat exchanger. Finally, fans attached to the furnace distribute the air via the ductwork throughout the building.


Sufficient aeration in the building averts mold and unpleasant odors. Air handlers and vent pipes make this possible by allowing fresh air from the exterior into the building. Ductwork then administers the new air throughout the premises.

Pointers on Selecting a Commercial HVAC

Planning and designing before installation are a prerequisite for selecting the suitable commercial HVAC for your building. Here are crucial considerations to aid you in the selection of a commercial unit.

The Size of Your Building

The right size of HVAC unit ensures adequate comfort in the building. The larger the structure, the larger the commercial unit you will need. You require an HVAC contractor with experience to design a unit that fits your space. They will quickly determine the suitable size to guarantee low energy costs and consistent thermal activity in the building through load calculations.

The Price

Going for the cheaper option is not always wise choice. Cheaper equipment means lower efficiency and a shorter lifespan for your HVAC. However, this does not mean expensive machinery is always the best alternative. It is prudent to check quotes from different HVAC contractors and choose the efficiency, performance, and lifespan that you see fit. 


Commercial systems are the units you need for temperature regulation and air circulation in your building. Consult an HVAC contractor to guide you when picking out an HVAC unit. Find one who works specifically with commercial HVAC units.
