Understanding the Three Types of HVAC
Heating, ventilation and air conditioning play a crucial role in your home or office building's comfort. While most building owners view it as a valuable addition, there is some confusion regarding the different options available. HVAC contractor marketing materials might highlight the benefits of split systems, hybrid setups and ductless systems. But what are the differences, and which one is right for you?
Split Systems
Heating and cooling split systems are some of the most common. They're referred to as "split" systems because they contain separate units for heating and cooling.
Outside the home is the cooling unit. It uses a series of components to cool and pump hot air out of the building. Ducts deliver the cool air back into the space, keeping your structure cool on those hot summer days.
During the winter, the heating unit takes over. It usually sits in a basement or dedicated storage room. In split systems, gas creates heat dispersed throughout the building. These units work independently, but everything is controlled via a centrally located thermostat.
Hybrid Split Systems
A hybrid system works similarly to a traditional split system. However, it has the added benefit of switching between gas and electricity to heat the building. The user has complete control over these systems, and the goal of the hybrid setup is to mitigate energy costs.
Gas is more efficient at heating a home during frigid winters. But when that high-powered heating isn't always necessary, users can switch to electric heating to keep operating costs low.
Ductless Systems
These systems are also known as duct-free HVAC systems or mini-splits. Instead of utilizing large units and complex ductwork, these systems use individual units for every room.
The units can mount on the wall or in the ceiling. While they take up space, they provide independent control for every room. Users can control the temperature to their liking without affecting the entire building.
As the name implies, they also don't need ducts. Instead, they have tubing to deliver refrigerant to an exterior compressor. The installation process is more flexible. As a result, HVAC contractor marketing typically touts ductless systems as an excellent choice for home additions, accessory dwelling units and more.
