Why​ ​a​ ​Home’s​ ​HVAC​ ​System​ ​Is​ ​Different​ ​Than​ ​a​ ​Commercial​ ​One

While all HVAC systems have the same goal, and each type works along the same principles no matter where it is installed, there are important differences between the systems in private residences and commercial buildings.

7 Important Variables Between Commercial and Residential Systems

Many things are the same between HVAC systems in commercial and residential locations, but there are also many differences. Important differences include:

  1. Size. The greatest difference between commercial and residential systems is the size of the equipment. Commercial structures are usually much larger than homes and are filled with more people and electronics that create more heat in the building.
  2. Installation location. Residential systems are usually installed on the ground outside the structure. Those installed in commercial buildings are often put on the roof to save space and keep them from being vandalized.
  3. Standalone or modular systems. Residential systems are usually standalone models which cannot be modified or expanded, only replaced. Commercial setups are modular in nature, allowing them to be upgraded or downgraded as businesses need it.
  4. Packaged or split systems. Residential systems are split into indoor and outdoor sections. Commercial systems are considered “packaged” because they combine all necessary parts into one place.
  5. Drain system. Residential systems normally drip into a pan which then drains outside. Commercial systems require a more complicated drainage system due to the increased size of the system and the location of the unit.
  6. Venting. Residential systems normally require no additional ventilation consideration. They are outside where they can vent freely or can easily vent through a home’s windows. Ventilation is a concern for commercial systems because they are often placed inside of structures with no windows for protection. Such structures need to be vented for proper functioning of the equipment.
  7. Technical difficulty. Residences have relatively straightforward HVAC systems compared to those installed in commercial structures. Commercial systems require more thermostats (which require more wiring) and much more ductwork that must be run in more complicated fashions and other issues.

Repairing and Replacing Commercial and Residential Systems

Because commercial systems are larger and more complex than residential systems, they require more specialized training and experience with the equipment used in these setups. An experienced HVAC technician can diagnose the system in a business structure, but the work of repairing it may require multiple technicians.

The nature of modular commercial systems makes them more challenging to diagnose and repair than the single unit of a residence. Problems in a residential system can only be located in one or two locations, commercial setups have many more possibilities.

Businesses need to be sure when they hire an HVAC company that they choose one with technicians experienced in working with commercial systems. Residential setups are much simpler to diagnose and repair than larger commercial systems, and cannot properly prepare a technician to work on commercial buildings without proper training.
