Know your commercial heating and cooling system: HVAC basics

Most of the commercial business owners take their HVAC or heating/cooling system for granted. Without proper maintenance, we expect the heating system to keep the space warm during winters while the air conditioning units are expected to cool down the building during summers. However, efficient functionality is almost impossible without timely and proper maintenance.

But before we get into the intricacies and benefits of regular maintenance from a service provider for commercial HVAC near me, you need to first understand your system.

How does your cooling & heating system function?

All variants of climate-control machinery come with three basic parts. These parts include the source where warming or cooling of the air takes place, followed by the means that help with the distribution of the air to places that need heating or cooling and the device that helps regulate the entire system like a thermostat.

The warm air sources such as a furnace or for cool air like the AC (Air Conditioner) in the house often tends to use the very same control and distribution systems. If the house comes with a centrally located air conditioning system, the cold air has been designed to flow through same ducts as that of the heated air. The temperature of the entire house, whether hot or cold is controlled via same thermostat. While we know more about how your system functions, it is impertinent that you hire professionals for installation, maintenance, repair, or replacement services for commercial HVAC near me.

Distribution Systems for HVAC System

Once the air has been cooled or warmed at the cold/heat source, it needs to be distributed evenly throughout the home. This particular action can easily be accomplished with the use of gravity, forced-air, or the radiant systems that have been explained below.

1-Forced Air Systems:

The forced air assembly distributes the cold air produced by the central AC or heat produced by your furnace via a fan that is electrically powered. This unit is termed as the blower that forces air through the system comprised of the metal ducts to rooms present inside your home. As warm air travels through the furnace and flows into the rooms, cold air present in the room is extracted from another duct set. This is the return system for cold air, which is reheated by your furnace. This particular system is perfectly adjustable. You have a scope of decreasing or increasing the overall amount of the air that flows through the home. You can get the same done with help from professionals for commercial HVAC near me.

The central AC systems tend to use the very same system of forced air with the use of blower to dispatch the cool air all throughout the house while extracting the warmer air towards the central unit to be dropped in temperature.

Issues that might occur with your forced-air system is the fact that it can experience blower malfunctions. Additionally, the blowers can also be a bit noisy & add to your energy consumption units. However, it is surely an effective methodology that aids in channeling the cool or heated air through the house. If you happen to notice louder than normal noise coming from your blowers, you need to get immediate help for professional repair of commercial HVAC near me.

2-Gravity Systems:

Gravity systems basically work on the concept that the heated up air tends to rise while the cold air sinks. This is why the gravity systems fail to work for the air conditioning or AC systems for the distribution of cool air. They can only be used for hot air distribution. Households that employ the use of gravity system, usually have their furnace located below their floor. After the furnace is done heating up the air, the warm air rises & hence flows through the ducts in order to reach various corners of the house via the vents. The heat vents are generally positioned higher on the room walls as it needs to be located at a higher spot for the warm air to be distributed properly.

After the air in the room cools down, it sinks & enters the return ducts to be warmed up again by the furnace.

3-Radiant Systems:

The radiant systems tend to function by the process of warming up of the floors, walls, or the ceilings of the rooms. In simple terms, the system warms up the radiators present in your rooms. These objects later warm up the air present inside the room. A section of the system uses an electric version of heating panels in order to generate proper heat that can be radiated all throughout the room. Like the gravity heaters, the panels used for the system are generally installed in places where the climate is warm. This is where electricity tends to be comparatively inexpensive. Also, the radiant systems can’t be used for distribution of cool air coming from the air conditioners.

The convectors and radiators are common means used for the distribution of heat in homes that pre-date the modern era. These systems might either depend on the gravity or the circulator pumps. This particular system can also be termed as hydronic system.
