How Commercial HVAC Systems Work in Buildings and Structures

Ever wondered how commercial HVAC systems work in large buildings and structures? Get your answer, and how they're maintained, in this article.

You headed out for work this morning and started sweating the moment you walked outside. If you cracked an egg on the sidewalk, it would cook in seconds!

There's no denying that the global temperature is getting hotter. In fact, for the last 6 years, global temperatures were the hottest ever recorded!

Chances are that you have air conditioning in your home to help keep it at a comfortable temperature. But what about warehouses? How to HVAC systems work to cool down such a large area?

Before you melt in the summer heat, read on to learn how commercial HVAC systems work and how to keep them in tip-top shape.

What Are Commercial HVAC Systems?

First of all, what does HVAC stand for? The acronym HVAC stands for heating, ventilation, and air conditioning.

As the name indicates, a commercial HVAC system controls the heating and cooling of an indoor area like an office building or warehouse. These are some of the major pieces in the system:

  • Ductwork
  • Furnace
  • Heat exchanger
  • Refrigerant lines
  • Thermostat
  • Vents

A qualified HVAC specialist can install a top-quality system for you starting at $4000. Larger commercial spaces need larger, more expensive HVAC systems.

How Do HVAC Systems Maintain a Reasonable Temperature in Commercial Spaces?

Since HVAC systems handle 3 different functions, we should look at how it accomplishes each of these jobs. As we mentioned before, these three functions are ventilation, heating, and air conditioning.

Ventilation

The ventilation aspect of the system controls the flow of air in and out of the building. This helps prevent mold and build-up of harmful fumes.

Heating

On cold days, the thermostat signals the gas valve to pop open and ignite the gas burner in the furnace. Then, the burner heats the heat exchanger and warms the air as it flows through the exchanger. Finally, the warm air runs through a fan attached to the furnace and forced through the ductwork around the building.

Air Conditioning

To cool the air, an HVAC system uses refrigerants or substances that absorb heat. After the compressor pressurizes the refrigerant, it moves into a condensation coil, which transforms the gas into a liquid. Finally, a blower pulls in warm air and forces it over an evaporator and the liquid refrigerant becomes a gas again as it absorbs the heat from the air, making the air cooler.

Taking Care of Your HVAC System

Since your HVAC system takes care of you and your business all year round, you should take the time to take care of the HVAC system! Making regular annual appointments for an HVAC expert to come to maintain your system ensures your HVAC system stays functional for as long as possible.

The most important part of the system to keep up with is the furnace. Things like a cracked heat exchanger or excess carbon monoxide can cause detrimental problems in your system.

While not all commercial spaces need to have industrial-sized HVAC systems, having one will make entering and working in those spaces much easier in the sweltering heat. Not only that, but materials stored in warehouses fare better for longer periods in climate-controlled environments.

We hope you loved reading this article and that you learned a few things about how commercial HVAC systems work in large spaces like warehouses. If you're looking to add an HVAC unit to your commercial property, we can help you get it done. Contact us today to get started!
