Commercial HVAC Installation
Most commercial HVAC installation projects are designed to improve indoor comfort, enhance efficiency and maximize employee productivity. In new construction or retrofit applications, the commercial HVAC contractor plays a key role in engineering the system to minimize operational costs and reduce repair expenses. The professionals at McWilliams Heating, Cooling and Plumbing understand that a successful commercial heating and AC installation requires proper planning, knowledge, resources, and execution.
Commercial HVAC System Design
The heating and cooling load for two businesses housed in identical buildings can differ dramatically depending on occupancy rates and generated heat. Retail environments and heavy equipment can be especially challenging, and they add substantial complexity to the design equation. In many instances, the HVAC system should include an economizer, a make-up air unit, and advanced controls.
At McWilliams Heating, Cooling and Plumbing, we rely on sophisticated ACCA Manual J formulas to determine the building’s precise requirements for conditioned air in all seasons. Equipment for commercial applications is selected based on the following criteria:
- Building Size
- Local weather data including humidity and temperature history
- Ceiling height
- Perimeter envelope tightness and integrity
- Insulation R-values
- Duct leakage
- K-values for windows and doors
- Machine generated loads
- Occupant generated loads
- Process generated loads

Commercial HVAC Installation Process
Commercial air conditioning installation costs can be controlled by following a tight construction schedule. At McWilliams Heating, Cooling and Plumbing, we always coordinate with the general contractor to ensure every installation goes smoothly with minimal delays. The impact of other trades on the construction process can be significant, so it’s critical to partner with an HVAC contractor who understands the importance of establishing a good working relationship with the other subcontractors.
For both new construction and retrofit applications, we pay special attention to the air distribution system since it plays a critical role in comfort and efficiency. On all of our projects, the ductwork is designed according to ACCA Manual D and installed to UL 181 and ASHRAE 90.1 standards.
Once the equipment is set, we charge the units with refrigerant and make the final connections. The system is air balanced to ensure the volume of conditioned air at the air handler is delivered to every room in the building according to the original engineered design.
Energy Efficiency Upgrades
Rising energy costs and environmental regulations have led to the development of technologies that save energy and reduce harmful emissions. Installing energy-saving equipment can improve HVAC system performance by up to 50 percent. Here are a few of the upgrades we recommend.
- Energy recovery ventilation
- Programmable controls
- Economizer technology
