Differences Between Residential and Commercial HVAC
When it’s time to perform maintenance on your HVAC system, it can be tempting to look at residential unit solutions; they’re often less expensive and more simple to perform.
However, this could be a drastic mistake. If this maintenance is under-performed, you could end up paying more money in the long run, while also feeling the heat of frustration. That’s why it’s important to understand the differences between both of these systems.
Residential and commercial HVAC systems both ultimately serve the same purpose: to control the temperature of the environment they’re in. However, they also have many key differences.
For instance, they require different levels of power to operate. They also have varying levels of size, location, complexity, drainage, and more. We invite you to read further to compare these systems, and how they uniquely function in their respective settings.
Location
Residential HVAC systems are commonly located on the side of a house, or in the backyard. This makes them easy to access by a technician while also staying out of sight for aesthetic reasons.
Commercial HVAC systems, on the other hand, are typically located on the roof of their building. This is to accommodate their larger size, prevent noise disturbances, minimize any tampering with the unit, and provide technicians with a safe and non-obtrusive location to perform maintenance on the system.
Size & Complexity
Commercial HVAC systems are notably larger than residential systems. This is because they are expected to maintain the temperature of a much larger area than residential units are.
They’re also more complex than residential systems! In a large commercial building, you may want to have control over partitioned areas of the building. This requires more complex design and functionality, and will certainly require a more elaborate draining system than most residential units would need.
Maintenance Requirements & Cost
A more complex system requires a deeper knowledge of unit maintenance. In many cases, home HVAC systems can be maintained by the homeowner, or via a quick visit by a technician.
This is not the case for commercial systems. For these systems, it is necessary to hire an experienced technician who is familiar with a unit’s functionality and build in order to provide proper care. This means, of course, that the cost of maintaining a commercial HVAC system will be much higher.
Mechanism
The mechanism of a commercial HVAC system can vary depending on the structure of the building it’s meant to serve. These units are often given a modular design, whereas residential systems typically exist as a standalone unit that’s split between the inside and outside of a home.
Because a commercial system has a modular design housed in a single unit, the different components can be easily found and tended to in one place. This is also a more conducive design for expanding or modifying the unit in some way, which a residential unit would not be capable of.
Drainage
Just about every part of a commercial HVAC system is larger than what you would find in a residential system, including the draining system. Because residential units are smaller, they usually only require one drain pan that’s located outside of the house.
A commercial system though, will require a much more intensive drainage system with multiple pipes and pans that ensure 100% evaporation, and reduce the chance that it might overflow.
At the End of the Day
Residential and commercial HVAC systems will both provide their respective settings with the temperature control that is expected of them, granted in very different levels of scope! So long as you’re happy and comfortable where you are, you can be rest assured that your unit is achieving the goal it sets out for.
