Frequently Asked Questions about Commercial HVAC

How can I save money on commercial HVAC costs?

Implement energy-efficient practices and strategies that includes:

• Upgrade to High-Efficiency Equipment: Invest in high-SEER and -AFUE rated HVAC equipment.
• Optimize Thermostat Settings: Use a programmable or smart thermostat to control temperatures and reduce HVAC usage.
• Regular Maintenance: Schedule preventative maintenance twice a year.
• Seal Air Leaks and Improve Insulation: Ensure proper insulation in the building envelope and seal any air leaks.
• HVAC Zoning: Divide your building into separate zones with dedicated temperature controls.
• Regularly Clean or Replace Air Filters: Keep air filters clean to improve airflow and energy efficiency.
• Ventilation: Implement demand-controlled ventilation to minimize the amount of outside air that needs conditioning.
• Employee Awareness: Encourage energy-saving practices among your employees, such as turning off lights and equipment when not in use.

By implementing these cost-saving measures, you can significantly reduce your commercial HVAC costs.

How does geothermal heating and cooling work?

Geothermal HVAC systems use the stable ground temperature as a heat source in winter and a heat sink in summer. A network of pipes (a ground loop) circulates fluid underground, absorbing heat from the earth in winter and transferring it into the building. In the summer, the process reverses, A heat pump extracts heat from the home and transfers it to the cooler fluid, which is then dissipated into the ground. Geothermal HVAC is highly energy-efficient, although installation costs can be higher due to the ground loop installation. Geothermal systems reduce energy use and have a smaller carbon footprint.

What is an Air Handling Unit (AHU)?

An Air Handling Unit (AHU) is a major component of many commercial HVAC systems. It's a large metal box that contains a blower, heating and/or cooling elements, and filters. AHUs regulate air temperature, humidity, and quality in commercial spaces.

What is a chiller, and how does it work?

A chiller is a refrigeration system that cools water or other fluids to a low temperature. This chilled water is then circulated through pipes to air handling units or fan coil units, which cool the air in the building. They are typically more energy-efficient for large cooling applications compared to standard air-cooled AC units.
