Contact us for a consultation and let us guide you through the process.


Types of Commercial HVAC Systems


Every commercial building has unique HVAC needs. Factors like building use, design, and efficiency standards are evaluated to determine the best solution for your space. Whether it's optimizing your existing system or exploring new, high-performance options, we'll help you create a long-term plan that maximizes comfort and minimizes costs.


  • Mini-Split Systems: Single-Split Sytems are the most cost effective option for small spaces or supplementing an existing system, but they are only able to heat and cool individual spaces. For larger commercial spaces a Multi-Split system allows for multiple zones.
  • Variable Air Volume (VAV) Systems: VAV systems offer precise temperature control and energy efficiency for commercial buildings. By adjusting airflow to meet the specific needs of different zones, VAV systems optimize comfort while minimizing energy waste. This flexible approach allows for individualized temperature control in each space, ensuring a comfortable and productive environment. VAV systems also offer potential energy savings through features like variable frequency drives and supply-air temperature reset.
  • Variable Refrigerant Flow (VRF) Systems: VRF systems utilize inverter-driven compressors to precisely control refrigerant flow. This advanced technology allows the system to adapt to the needs of each indoor unit, optimizing comfort and energy efficiency. By varying the compressor speed, the system can precisely match refrigerant flow to the needs of each indoor unit. Each indoor unit in a VRF system has its own control system that communicates with the outdoor unit. This allows each room or zone to request the precise amount of cooling or heating it needs. The ability to customize comfort in different zones makes VRF systems incredibly versatile and efficient. Whether dealing with varying occupancy levels, unique building layouts, or specific temperature preferences, VRF systems adapt to provide optimal comfort and energy savings.
  • Constant Air Volume (CAV) Systems: CAV systems distribute conditioned air throughout a building at a constant rate. However, this approach lacks the flexibility and efficiency of VAV systems, which can adjust airflow to meet the specific needs of different zones. This was once the most common type of system and remains in use in many applications. VAV systems have a more attractive option for new construction.
  • Heat Pumps: Heat pumps offer an energy-efficient solution for heating and cooling commercial buildings. While they excel in moderate climates, their efficiency can decrease in extreme temperatures. Additionally, heat pumps typically don't offer the same level of zoning control as systems like VRF or VAV, which can individually adjust temperature and airflow in different zones, but for certain applications they are the ideal system.

Reducing Operating Costs

Your HVAC system can be a major contributor to your building's energy expenses. To lower those costs, focus on two key strategies: reducing the amount of heating and cooling your building needs, and improving the efficiency of your HVAC system itself.


1. Reduce Your Building's Heating and Cooling Needs

  • Upgrade to Energy-Efficient Lighting: Traditional lighting generates a significant amount of heat. Switch to LED lights, which produce less heat and consume less energy.
  • Optimize Building Insulation: Proper insulation prevents heat transfer, keeping your building cooler in the summer and warmer in the winter. This reduces the workload on your HVAC system.
  • Improve Ventilation: Good ventilation helps regulate temperature and humidity, reducing the strain on your HVAC system. Ensure your building has proper airflow and consider using strategies like natural ventilation when possible.
  • Invest in Energy-Efficient Equipment: Replace outdated electronics and appliances with energy-efficient models. Look for ENERGY STAR certified products to maximize savings.

2. Increase Your HVAC System's Efficiency

  • Schedule Regular Maintenance: Just like a car, your HVAC system needs regular tune-ups to operate at peak efficiency. Schedule professional maintenance to identify and address potential issues before they become major problems.
  • Replace Air Filters: Dirty air filters restrict airflow and force your system to work harder. Replace filters regularly to maintain optimal performance and improve indoor air quality.
  • Install Programmable Thermostats: Programmable thermostats allow you to customize temperature settings based on occupancy and time of day, minimizing energy waste when the building is unoccupied.
  • Ensure Proper Sizing: An oversized or undersized HVAC system will operate inefficiently. Ensure your system is correctly sized for your building's needs to maximize performance and minimize energy consumption.

3. Additional Tips:

  • Consider Zoning: If your building has different zones with varying needs, consider a zoning system to control temperature and airflow individually.
  • Utilize Natural Light: Maximize natural light to reduce the need for artificial lighting, which generates heat.
  • Monitor Energy Usage: Track your energy consumption to identify areas for improvement and measure the impact of your efforts.


By taking a comprehensive approach to HVAC efficiency, you can significantly reduce your energy bills and create a more comfortable and sustainable environment for your business.
