Guide for HVAC Commercial Installation

Whether the building is owned by the business owner, managed by a facility manager, or leased to a tenant, each has a slew of responsibilities. Besides managing staff and providing services to customers. They also have an obligation to the building structure and all component parts. They need to guarantee that they are in good condition. In other words, if your commercial HVAC system is not properly maintained and identified. You are likely to suffer a loss of income. And in some cases, you might lose customers too.

Let’s face it, HVAC systems for commercial buildings are quite complex. Those of you who thought residential HVAC systems were complicated are about to experience a less than pleasant surprise. That is why we have compiled this wonderful guide on residential and commercial HVAC systems. We hope this article will be helpful to you in maintaining the AC in your building. So that you can keep the costs and repair costs of the AC system low and therefore keep your commercial HVAC utility costs low as well.

The next time you are in need of commercial HVAC help and you are a Pittsburgh business owner or facility manager. Look no further than ART Industries Inc for HVAC for all your needs. We have technicians with extensive experience in commercial HVAC. We promise you a minimally disruptive, charmingly educational experience whether you need extensive repairs and replacements or if you simply have questions. Now let’s get started.

What is Commercial HVAC?

In the commercial sphere, HVAC (heating, ventilation, and air conditioning) systems have the same goal as residential systems. To provide high-quality, comfortable indoor air in an environmental temperature range of 72 degrees Fahrenheit and a relative humidity range of 40 to 60% during the day.

The heat that is released from burning fuel (such as oil, gas, or electricity) is often achieved through the burning of fuel. Obviously, cooling the air is the opposite of heat removal (naturally). As it involves extracting the hot air from the interior and cooling it down using refrigerant or water-cooled systems. Also eliminating any humidity at the same time. In a typical ventilation system, fans are used to introduce outside air to a building, pass the outside and re-used indoor air through filters, and expel the contaminated air from within the building. As a result, the CO2 concentration stays under 1000 molecules per million.

It is important to have an efficient ventilation system to reduce odors, dilute gases (like carbon dioxide), and prevent respiratory diseases from spreading. Without it, unwanted particles would cause stale air and increase mold and mildew growth.

The question is, how does your commercial HVAC system accomplish all of this? Let’s explore.

How Does a Commercial HVAC System Work?

Keeping a commercial building at a comfortable temperature requires three components: warm or cool air, a distribution system, and controls. Cool air from the building passes through the same ducts as heated air, and it is controlled by the same thermostat. However, the source will differ. 

Warm or Cool Air

In commercial HVAC, when the heating is turned on. The burners create combustion gas that passes through a heat exchanger. The hot air is then passed through the exchanger. Where it warms the air that is being passed through. In some cases, heat pumps transfer the warmth from outside to inside. Similarly to heat pumps. we can also use air conditioners to transfer indoor heat outside through a reverse process.

In some commercial buildings, a boiler system is used to heat the water which is then transported through pipes installed into the walls, floors or ceilings. Despite the fact that you may not notice the structure itself warming. You are likely to notice the air being warmed. 


It is true that the mechanical system circulates the air in a building by way of ventilation and the principle that warm air rises and cool air falls will help you. Air is continually pumped in and out, sometimes after it has been thermally altered.


Commercial buildings can use simple programmable thermostats, like those used in residential HVAC systems, to regulate all of this. The thermostats can be programmed to send various heating or cooling queues throughout the day.

It is also possible for commercial HVAC systems to be controlled directly with direct digital control (DDC), which is a bit more complicated. With more sophisticated commercial control systems. Building owners achieve increased energy efficiency and reliability from their HVAC systems. With the help of sensors, the central computer can monitor and respond to temperature schedules and even light schedules from a centrally located computer.

From the main workstation. Staff can manually adjust settings, giving users access to performance updates, troubleshooting, and maintenance tasks. Considering its capability and versatility. DDC is a more expensive option due to its sophistication and flexibility.

Users of both simple controls and DDC can implement temperature setbacks to significantly reduce their energy consumption. The setbacks can be reduced anywhere from 5% to 20%. In the context of a thermostat. A temperature setback is a period where heating and cooling are not needed, such as the time after work and when an empty building is in use.

Let’s go! Hopefully, now you have a better understanding of how an HVAC system works.
