Distinction Between Commercial And Residential HVAC System

Commercial Residential HVAC System

Regardless of whether summer is heating your distance or chilly weather has come around again, your comfort is dependent on your HVAC system. It is crucial to understand the differences between commercial and residential HVAC systems to be able to understand exactly what you should expect from each one.

Here are seven main differences comparing the two.


Because commercial spaces tend to include a fantastic deal more square footage as well as serving a larger number of individuals, their HVAC systems require more power than do residential systems. Sizing both systems is comparable, making use of these variables like square footage, the number of occupants, efficiency, and peak usage hours. Everyone these factors tend to have a higher worth in commercial areas, requiring a higher tonnage output for sufficient cooling and heating. Broadly speaking, electricity output for commercial units is larger, but a little less precise. You can also get commercial air conditioners for rent at the most affordable prices. In contrast, residential HVAC systems focus on more exact sizing for increased cost-efficiency.


Rooftops are a common location for commercial heating and cooling systems. Though not necessarily true, a major reason for placing HVAC units in this area has to do with the distance that they consume. Placing smaller, residential HVAC system elements behind or behind a house tends to be more practical due to both dimensional distance and structural characteristics that make rooftop installation less desired. There’s a variety of reasons associated with rooftop placement of HVAC systems for industrial applications, including:

  • Saving Space. In most commercial settings, space comes in a premium and owners and prefer to create use of fresh rooftop space.
  • Greater Security. In addition to dimensional size, commercial HVAC systems frequently require a greater amount of protection against vandalism or tampering. Rooftop installation permits for greater controlled access to industrial systems.
  • Noise Disruption. Operational noise from heavier systems may be disruptive. The rooftop placement allows for noise isolation.
  • Maintenance Access. A final rooftop placement consideration includes the capacity to conduct system maintenance without interrupting normal business operations.


The structure and components of a commercial HVAC system in comparison to some residential system varies considerably, particularly in complexity. Residential systems are relatively simple in their design as well as the components used. They generally include eight straightforward, standard components in every setup, which include less intricate use of the occupants. However, commercial systems need to be more adaptable to the type of building or level of service they are providing. Together with the basic components required for distributing and controlling cooling and heating, commercial HVAC systems often require additional elements to limit or confine treated air in a variety of zones of the building. The reason for this relates to the usage of different zone occupancy and activities which take place during different times of the day or night. Commercial units also tend to demand innovative systems for exhaust alleviation, which are not necessary for most residential installations.


Residential HVAC systems are split systems. This means that certain elements exist in the indoor part of the system while some are present in the outside portion of the system. Modification and expansion of those components aren’t possible. By comparison, a commercial HVAC system is significantly more flexible, allowing owners to accommodate changing demands as their operations increase or decrease. Commercial systems are modular, meaning that adding or taking away different components of this machine can happen to raise or decreasing heating capacity. The various parts of a commercial system have been housed together, making updating and maintenance simpler.


The drainage system included with a residential HVAC system is compact and contained in a much smaller region, which is often a single pan positioned outside the house. The size and power of most commercial methods make drainage much more complex. It is common for industrial HVAC systems to include multiple pans and pipes to accommodate drainage, and ensure complete evaporation and prevent overflowing. Consequently, these elements increase the necessary dimensional space necessary to adapt them.


A residential unit handles heating, cooling, and humidity controller with two elements: an outside compressor and an indoor evaporator (split unit). Additional components are not common, because general versions in a residential installation don’t incorporate a wide assortment of extremes. This is not true with a commercial HVAC system, making use of thermostats, dampers, blowers, and other systems to impact unique zones of the building during different hours of the night and day. The reason these extra pieces of equipment are necessary relates to the fact that all HVAC functions are included in a single unit rather than in a split unit.


Residential HVAC systems are relatively straightforward to keep. Typically, restricted maintenance is necessary at the beginning of each seasonal phase for either the air conditioning system or the furnace, and costs are minimal. Maintenance on a commercial HVAC system requires a great deal more commitment and effort because of the sophistication of the numerous systems, the size of the device itself, and the various elements of its mechanics. Commercial systems require additional observation, which isn’t a common requirement of a residential unit. This extra focus, sizing, and sophistication adds a lot of costs to maintaining a commercial HVAC system, which makes it far more expensive to operate. But we suggest that you can also get commercial air conditioners for rent at an affordable price and get relax from all the worries.


Apart from being more expensive to keep, the initial investment cost of a commercial HVAC unit is typically higher. Merely to help establish a baseline, the estimated cost of a basic, commercial rooftop HVAC program will start near $4,000. However, there are several variables, which affect the initial cost of a commercial system, including:

  • The capacity of the Unit
  • SEER (Seasonal Energy Efficiency Rating)
  • Quality and Brand
  • Optional System Features
  • Climate and Location

Remember that higher quality, more efficient HVAC systems tend to cancel their first costs through longer warranty periods, lower maintenance costs, and lower operating costs.

What is necessary to cool and heat a house fluctuates from what is necessary to cool and heat a commercial building. Even though they produce the same objective, due to these various requirements, the HVAC systems used in each program are different. It is important to know the differences, what to expect from every type of program, and also the difference in prices.
