5 differences between residential and commercial HVAC systems


Keeping your home or business at a comfortable temperature throughout the year means having the right HVAC system. Your home doesn’t need a large commercial system, and your business shouldn’t have a residential system installed. There are many differences between residential and commercial HVAC systems. While they both heat, cool and ventilate buildings, they are unique in how they are installed and how they operate.


System Size


One of the most noticeable differences between residential and commercial systems is their size. Commercial HVAC systems come in larger sizes than residential systems, since they need to cool or heat a much larger area. No matter which type you need, it’s important to size it correctly. This helps ensure that your system can heat and cool your home or office efficiently.


System Location


Where residential and commercial systems are located is another major difference between them. Technicians usually install residential systems next to a home or on the roof.

Technicians generally install commercial systems on the roof due to how large they are.

Putting them on the roof keeps them out of the way while also providing them with plenty of space.


Standalone vs. Modular


Residential systems come in standalone units that technicians can easily install. Technicians cannot add onto or modify these systems in any way once they are installed. Commercial systems come in modular forms that allow for adjustments or modifications as needed. This helps ensure that commercial buildings have the right heating and cooling capacity. For example, commercial systems might require an additional unit if they need to heat and cool a larger area.


Split vs. Packaged


This refers to the set up of these systems. Residential systems typically have separate or split components, such as an outdoor compressor and an indoor evaporator. You can also get them as a packaged unit. Commercial systems generally come as a packaged unit that contains all of the cooling and heating components needed. Split commercial systems are available as well. Since commercial systems are more complex overall, this setup allows technicians to access all parts and components more easily. Keep in mind that commercial units usually require the installation of several thermostats to cool or warm up different areas or zones as needed.


System Drainage


Residential and commercial systems differ in terms of how they drain. Residential systems usually have one drip pan for drainage. Commercial systems generally have several drip pans and pipes installed to ensure proper drainage. These drainage setups help lower the risk of having the system overflow from too much condensation or moisture.


Importance of Regular HVAC Maintenance


Whether you have a residential or commercial HVAC system, having routine maintenance done is important. This service helps keep your heating and cooling system in good working order, which reduces your risk of needing repairs. Some of the tasks technicians include are changing filters and checking refrigerant levels. Having regular maintenance done on your residential or commercial system can also help it last longer.
