Nowadays, it’s difficult to imagine a large building without a functional HVAC system. With climate conditions becoming more extreme and unpredictable, it is only prudent for anyone who owns or operates a large building to ensure the comfort of those who work, conduct business, or shop there. If you’re on the lookout for a new HVAC system for your commercial building, several factors are to consider. You can buy the best HVAC product line for your building, but if it is not installed correctly, it will fail and cause a slew of problems.

Key Considerations When Installing a Commercial HVAC System

Installation of an HVAC system must be done following the typical characteristics of your building, which is why individuals should employ an HVAC professional. Proper HVAC installation entails more than simply repairing and securing the HVAC system.  The following are some of the factors to consider.

Installation Location

One of the most critical factors is indeed the location, particularly the location of the Fan and Coil.  The garage, attic or crawl space may be suitable if the HVAC system is not exposed to the elements and all applicable local regulations are followed. The fan coil unit can be installed in the basement, cabinet, or utility room, depending on the requirements of your local codes. Ascertain that your HVAC system is not located near gases or areas where people frequently move from one location to another. It should be in a remote area where it can operate without jeopardizing the comfort of the occupants of your home. The commercial HVAC company can advise you on the best location for your HVAC system. If you don’t already have an ideal place for it, create one before heading to the store to purchase a new HVAC system.

System Size

Installing equipment that is the proper size for one’s commercial space is critical. Sizing does not refer to the physical dimensions of the unit in this case; instead, it refers to the process of evaluating your heating and cooling requirements and selecting a system with the functional capacity to meet them. If you choose a too-small system, it will have to run constantly to keep the premises cool, increasing your energy costs and possibly incurring repair costs if the system fails under load. On the other hand, if it is too big, the building will cool very quickly. The on/off cycle will be accelerated, making it nearly impossible to dehumidify the air adequately.

Requirements For Maintenance

Maintaining your HVAC system is necessary to ensure its efficiency and safety. Intervals of maintenance can be scheduled with your HVAC professional. You should be able to cover the cost of routine maintenance to ensure that your machine is always efficient and reliable. Commercial HVAC systems are large and require intensive maintenance, so consult an HVAC professional to determine your expectations. Consider purchasing a system that is durable and robust and will not fail easily.


Once you’ve determined your installation budget, begin collecting estimates from local HVAC providers. Each will include the cost of materials and labor for installation. Request a detailed breakdown of the installation’s costs so that you can compare the costs for the categories listed:

  • Equipment
  • System startup
  • Ductwork and piping
  • Controls
