What Is HVAC and How Does It Differ From AC

The difference between HVAC and air conditioning equipment is one of the most prominent sources of confusion for householders. Although the two are not the same, many people aren’t clear about how they differ.

The difference between HVAC and air conditioning is more frequently debated than you would believe. Heating and air conditioning are designed to make our homes and workplaces pleasant all year. We understand the need for air conditioning. But what exactly is an HVAC system, and how does it vary from a standard air conditioner?

What Exactly Does HVAC Do?

Heating, Ventilation, and Air Conditioning (HVAC) is a system that combines your furnace, AC, and ductwork throughout your house or company to keep the interior air pleasant throughout the year. 

An HVAC system also maintains indoor air quality. When the air conditioner or heater is turned on, the ventilation system pulls air from the inside. It recirculates it with outside air, screening it to remove contaminants that might cause health problems in certain people.

An In-Depth View At How Your Heating And Cooling System Works

In some cases, the HVAC units may work independently of one another. However, it’s more normal for each unit to act in tandem with the others. Both central heating and air conditioning are included in these combined systems.

But let’s be clear: your HVAC system is much more than merely a simple method to heat or cool your home or office. It’s a technique to completely improve your indoor air quality and make your home more comfortable for everyone.

And How Does AC Really Work?

By eliminating heat and humidity from the interior air, an air conditioner offers chilly air within your house or enclosed space. It transports the undesired heat and humidity outdoors while returning the cooled air to the internal environment. 

A conventional air conditioner or cooling system includes three primary mechanical components: a compressor, a condenser coil, and an evaporator coil, and it employs a specific chemical called refrigerant. These parts work together to transform refrigerant from gas to liquid and back again fast.

The compressor elevates the refrigerant gas’s pressure and temperature before sending it to the condenser coil, turning it into a liquid. The refrigerant then returns to the house and enters the evaporator coil. The liquid refrigerant evaporates and cools the indoor coil at this point. 

Indoor air is blown across the cold evaporator coil, which absorbs the heat from home into the refrigerant. The cooled air is pumped throughout the house while the hot gas is returned to the compressor outside. As the refrigerant returns to a liquid condition, the heat is discharged into the external air. This process repeats itself until your home reaches the appropriate temperature.

Why Is It Better To Have An HVAC System?

An HVAC system is a more comprehensive solution than an air conditioner for various reasons.

  • You may set it to automatic at the temperature you choose and forget about it with an HVAC system. It will run on its own to maintain your selected degree of comfort.
  • Your air conditioner isn’t circulating any of the air inside your home. They’re drawing in outside air, chilling it, and blowing it inside the building.
  • Mold, mildew, and other allergens are less likely to occur in an HVAC system that is properly maintained.
