Key Factors to Consider for Commercial AC Installation

The need for a comfortable working environment is vital for both employee productivity and customer satisfaction. As a business owner, investing in a reliable and efficient commercial AC system is a crucial decision you’ll make. Proper AC installation is essential to ensure optimum performance, longevity, and cost-effectiveness of your HVAC system. 

One of the primary considerations for commercial AC installation is choosing the right type of system that suits your specific needs. The size and capacity of the system will determine its energy efficiency and impact on your utility bills. Before deciding on the ideal AC system, it is crucial to consult with experienced professionals at Dunham Service, who can carefully assess your requirements, your building’s structure, and other essential aspects to determine the best-suited solution for your business. Read on as we outline the key factors to consider when installing a commercial air conditioning system in your commercial or new construction property.

Choosing the Right Type of AC System

As mentioned earlier, selecting the appropriate air conditioning system for your commercial space is one of the most critical decisions you’ll make during the installation process. You’ll want to carefully consider system types such as split systems, packaged units, Variable Refrigerant Flow (VRF) systems, and other commercial HVAC solutions that cater to various business needs. Each system type has its benefits and drawbacks, and the choice depends on your specific requirements, budget, and building structure.

Split systems comprise separate indoor and outdoor units, which can offer great flexibility, allowing for multiple indoor units connecting to a single outdoor unit. This system provides targeted cooling in different areas but may require larger ductwork in your commercial space. On the other hand, packaged units centralize the indoor and outdoor components into a single enclosure. They can be installed on rooftops or outside your building, saving valuable space inside.

VRF systems are another popular choice for commercial AC installations, offering multiple indoor units that can serve various rooms and provide simultaneous heating and cooling. These systems work exceptionally well for larger applications, providing improved energy efficiency, reduced operational costs, and individual room control.

Proper Load Calculation and System Sizing

Load calculation and system sizing are vital factors in achieving optimal efficiency and longevity for your commercial AC installation. Undersized systems will struggle to cool your space effectively, leading to increased energy consumption and possible component damage due to overworking. Conversely, oversized systems may cost more than necessary, both upfront and in energy consumption, and create hot and cold spots.

To determine your commercial space’s proper load, our HVAC professionals will assess factors including the building’s size, orientation, insulation, window types, and even local climate, among others. This allows a more accurate calculation of the heating and cooling needs, ensuring that the system you choose is sized appropriately for peak performance and energy efficiency.

Energy Efficiency and Cost Savings

Energy costs will always be a top priority for businesses continuously looking to minimize expenses. The commercial AC system you choose should provide efficient heating and cooling without compromising comfort. For this reason, paying close attention to the Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER) ratings can help you make an informed decision about the commercial AC system to install.

Higher EER and SEER ratings mean better energy efficiency, which translates to lower operational costs. However, it may involve a higher upfront investment. Consulting with our HVAC experts will help you strike the right balance between upfront and long-term costs, ensuring maximum savings and performance from your commercial air conditioning system.

Indoor Air Quality (IAQ) and Ventilation

Creating a comfortable and healthy work environment is essential for increased productivity and employee satisfaction. Improving indoor air quality goes hand-in-hand with temperature control and should be an integral part of your commercial AC installation strategy. Commercial HVAC systems can be equipped with advanced filtration systems, UV lights, and proper ventilation to help maintain good indoor air quality.

Ensuring proper ventilation ensures that there is a consistent supply of fresh, pollutant-free outdoor air, which significantly improves the workspace’s IAQ. By addressing IAQ concerns during the installation process, you can create a healthier, more productive environment for employees and customers alike.


A well-planned commercial AC installation drives your business’s success by creating a comfortable and cost-effective environment in which to operate. By considering essential factors such as the type of system, proper load calculation, energy efficiency, and indoor air quality, you can ensure a successful installation that maximizes comfort and savings.
