While searching for HVAC systems, you might have come across commercial and residential units. The residential HVAC and commercial systems are made to provide cool or hot air. However, both systems have huge differences and are required in different areas and sizes. Let’s explain these differences in detail:

  1. Size of the HVAC systems

Since commercial HVAC systems are installed in a large building that includes different floors, the business owners have to find much bigger units than a residential HVAC system. The requirement to condition the huge area is completely different from the need to get chilled air in a small space.

In a residential home, the rooms can become chilled within a few minutes using the AC systems. However, the same system can’t be used in a big area as it won’t make much or any difference.

  1. Operating Power

Any machine that is bigger in size and produces more noise is likely to consume more energy and power. Commercial systems are huge and extremely powerful compared to residential units. Hence, you are likely to get fewer electricity bills while using residential HVAC units than commercial ones.

  1. Placement of the System

Commercial HVAC systems are generally installed on the building’s roof. Since they are huge and require more space, you can’t place the systemaround the building. One advantage of installing the system on the roof is that the technicians can easily fix issues.

On the other hand, the ductless split system is generally used in residential buildings. This system has an indoor part with a fan to disperse treated air. You don’t have a furnaces option. This unit can be installed on the ceiling, floor, or walls.

  1. Split system or packaged system

Since commercial building requires a packaged system, you will usually find the heating and cooling units within a single system. Due to this reason, technicians have difficulty finding the main unit with issues during the maintenance process. Comparatively, residential systems include two components: an outdoor compressor and an indoor evaporator.


We hope now you understand the difference between a commercial system and residential HVAC units. You should check the benefits of various types of systems before installing one.
