Difference Between Residential Vs Commercial AC

When it comes to AC systems, there are two main types: residential and commercial. These two AC systems are similar but very different in others. They both keep people comfortable indoors, but there is still a significant difference between them regarding their function and use. If you’re unsure which type would be best suited for your needs, understanding these distinctions can help make informed decisions about how each system works. This blog post will outline and talk about five of the most significant differences between residential vs commercial AC.

Here are the five key distinctions to keep in mind:


The main difference between residential vs commercial AC is the size. Residential AC systems are smaller in size compared to commercial ones. A residential unit would only typically cool a small space such as your own home. But if you have an office building or a warehouse with thousands of square feet, it makes sense for a commercial AC system! Large commercial spaces need more extensive cooling capabilities because they require more energy and power to cool all areas comfortably.

The commercial units in an office building, department store, or warehouse are designed to maintain a comfortable temperature for employees and customers all day. Commercial AC systems have become complex in function and design with high expectations and thus require special care.


When it comes to placements of AC systems, residential units are often located either in the backyard or alongside the house or building. The unit’s location is easy to access, allowing technicians to be out of plain sight when doing repairs and maintenance.

In contrast, a commercial unit is placed on top of a building. Because of its large size, placing it on the rooftop is space-saving and keeps away noise disturbances. Having your commercial AC units on top means that technicians have quick access to their work with little to no obstructions.


You might be surprised by how much difference there is in the installation process of residential vs commercial AC units. Residential units are easier to install, mechanically and aesthetically, because they don’t need significant piping and ductworks.

On the other hand, commercial units involve greater complexity in installation due to different requirements ranging from size to electrical supply needs. However complex, if commercial AC installation is done correctly by a licensed HVAC company, it can lead to a highly effective environment that can help you save money long-term. Luckily, at Daffan Mechanical, we’ve got our trained technicians for all types of cooling and heating installation in Stephenville, TX, whether residential or commercial.


Another significant difference between residential vs commercial AC systems is their drainage. With residential units, the entire system can drain in a single pan. Since residential systems are smaller, they also require smaller drainage systems.

Commercial AC units require a much more elaborate drainage system than residential ones. They cool buildings that can be several stories tall, meaning there’s always moisture cycling through their systems no matter what. So, to drain correctly and avoid overflowing, commercial units are built with multiple pans and pipes, and sometimes even their drainage system!


A key difference in residential and commercial AC units is their maintenance. Homeowners can easily do minor maintenance, like changing the filters or cleaning. Since residential units are smaller and more straightforward, homeowners can sometimes do the maintenance themselves.

In contrast, commercial AC units need more care than residential because of their size, location, design, and components. This means that you’ll need the help of a fully licensed and trained HVAC professional when doing maintenance. These professionals are experienced with commercial HVAC maintenance and familiar with its structure and components. Since maintenance of larger units is more expensive than smaller ones, repairs tend to be the same. That’s why it is essential to keep up with your commercial unit’s regular maintenance to avoid costly repairs.

Machine Complexity

A residential AC system is less complex than its commercial counterpart because it only needs to operate a few rooms rather than all sorts of spaces. This means that the settings and features are minimal compared with what’s required on big-scale properties. While a commercial AC system is a more complex machine, having additional features such as multiple fans and heating capabilities.

Length of Use

 Since it is designed to cool a smaller space and its smaller size, a residential AC should not be used constantly throughout the day. While commercial AC, with its particular parts and components, can be used continuously.

With the top 7 significant differences between residential and commercial AC systems outlined above, you now have a robust understanding of which is best suited to your needs. When purchasing a new AC system, always consider its size, placement, installation, drainage, maintenance, machine complexity, and length of use. Once you’ve narrowed down your choices, it will be easy for you to choose which is best. Still undecided? Get the help of an experienced AC provider!
