A workplace or any commercial space should be conducive to productivity, comfort, and safety for everyone who works in it. One of the most crucial components that contributes to this is a properly functioning HVAC system. Here’s why it is a significant investment for any business and what you need to know about it before installing your preferred one.

What Is a Commercial HVAC System?

A commercial HVAC system is an advanced setup tailored for the unique demands of large-scale structures like office buildings, expansive warehouses, hospitals, schools, and various other business-related environments. Unlike residential HVAC systems, commercial ones are more powerful in ensuring an optimal indoor climate, balancing temperature and air quality across extensive spaces. They require specialized installation, maintenance, and repair services for optimal functioning and longevity.

Importance of Proper HVAC Systems for Commercial Buildings

Occupant Comfort

For office employees and clients alike, comfort is essential to their overall experience. A well-ventilated space with optimal temperatures can help enhance productivity, potentially leading to improved financial outcomes for businesses.

Indoor Air Quality (IAQ)

A sound commercial HVAC system ensures healthy indoor air quality by filtering out pollutants, allergens, and other harmful particles. Poor IAQ can lead to a range of health issues for employees, such as respiratory problems, allergies, and headaches. By investing in a reliable HVAC system, businesses can promote a healthier working environment and reduce absenteeism due to illness.

Energy Efficiency

Heating and cooling buildings is one of the biggest energy expenses for businesses. By installing an energy-efficient HVAC system, companies can significantly decrease their utility costs while reducing their carbon footprint.

Building Preservation

Extreme temperatures and humidity levels can directly impact a property’s structure. Normally, when there’s excess moisture in the air, pathogens may grow, paints may peel, and wooden fixtures may rot. On the other hand, in extremely dry conditions, materials such as plaster and wood can become brittle and crack. A proper commercial HVAC system helps maintain a balance of temperature and humidity levels, preserving the building’s integrity and prolonging its life span.

Regulatory Compliance

Commercial buildings are subject to specific rules and regulations when it comes to ventilation and air quality. A well-maintained HVAC system can ensure compliance with these regulations, avoiding any potential fines or penalties. Additionally, regular maintenance and inspections can also prevent safety hazards and ensure the safety of employees and customers.

Types of Commercial HVAC Systems

Rooftop Units (RTUs)

Rooftop units are systems that integrate all the essential HVAC components—heating and/or cooling coils, compressor, condenser fan, air filter, and controls—within a single unit. As their name suggests, these units are strategically installed atop buildings and are thus designed to withstand all types of weather conditions from heat waves to snowstorms.

Rooftop units work like a general traditional air conditioning system. They are connected to the building’s ductwork and send conditioned air wherever needed.

RTUs are ideal for commercial buildings with limited indoor space as they do not take up any square footage. They are also much quieter because all their components are housed outside the building, and their installation location protects them from theft and vandalism. Your HVAC technicians will also appreciate the ease of access when it comes to maintenance and repairs.

Split Systems

A split system is simply an air conditioning system with its primary components separated and placed in different locations. The compressor unit and condenser are placed outside the building while the evaporator coil and blower are installed inside.

The air handler pulls in warm air from the inside and pushes it over the evaporator coil, which contains a refrigerant that absorbs the heat from the air. If you need warm air, the condenser in the outside unit heats the refrigerant, which the compressor then sends inside to warm the air.

Split systems are commonly used in small- to medium-sized commercial buildings. They allow for zoning, meaning different areas of a building can be controlled separately for better temperature control and energy efficiency.

Chiller Systems

A chiller is a cooling system that uses a liquid refrigerant to cool water or air, which is then circulated throughout the building. These systems are typically found in larger commercial buildings such as office complexes, hospitals, and hotels.

Chiller systems come in mainly two types: air-cooled and water-cooled. Air-cooled chillers work by using fans to blow air over the condenser coil, which absorbs heat from the refrigerant before it is circulated back inside the building to cool the air. Conversely, water-cooled chillers employ a cooling tower to remove the heat from the refrigerant before it is sent back inside.

Chiller systems are known for their high efficiency and low energy consumption. They can handle large cooling loads and can be easily expanded or modified to meet changing needs. They also boast longer life spans and a quieter operation, which are ideal for a workspace.

Variable Refrigerant Flow (VRF) Systems

VRF is a sophisticated technology that uses refrigerant as both its cooling and heating medium. These systems operate by connecting multiple indoor units to one outdoor unit through piping. The outdoor unit is equipped with a variable-speed compressor, which is designed to adjust its output precisely to match the cooling or heating needs of the individual zones within a space.

VRF systems can simultaneously cool and heat different zones within the same building, making them ideal for large commercial buildings with varying temperature needs. They are also known for their quiet operation and flexibility in installation as they can be easily retrofitted into existing structures without the need for major construction work.

Factors to Consider When Choosing a Commercial HVAC System

Load Sizing and Zoning

Accurately calculating the heating and cooling loads of a building is crucial when choosing the right HVAC system. Oversizing or undersizing a system can lead to energy inefficiency, discomfort for occupants, and potential equipment failure.

Zoning is also an important factor to consider. Buildings with varying temperature needs or different occupancy schedules may benefit from a multizone HVAC system like VRF.

Energy Efficiency

Commercial HVAC systems run all the time, which can result in high energy costs. When choosing a system, it is important to consider its energy efficiency and overall operating costs. Look for systems with high SEER (Seasonal Energy Efficiency Ratio) ratings. An ENERGY STAR-certified system can also provide significant energy savings.

Sustainable Technologies

When choosing a commercial HVAC system, consider sustainable technologies like heat recovery systems, evaporative coolers, and more. Recovery systems, for instance, can capture and reuse heat waste from a building while evaporative coolers use water instead of refrigerants as a cooling source. Consult with an HVAC technician to learn which systems have advanced features that can improve efficiency and sustainability.

Lifecycle Costs

Initial installation expenses are but one part of your lifecycle costs; you should also factor in long-term maintenance, warranties, and operational energy costs. Your HVAC system should not only be affordable to install but also maintain and operate in the long run.

Manufacturer and System Reputation

Opting for a reputable manufacturer and a well-reviewed system can significantly reduce the risk of equipment failure and ensure quality performance. Research different manufacturers and their systems to make an informed decision.
