Frequently Asked Questions about Commercial HVAC

Find answers to common questions about commercial HVAC systems, services, and finding the right contractor for your business in UK.

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. The AHU takes in outside air, filters it, and then heats or cools it before distributing it through ductwork.

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. Chillers are often used in large commercial buildings, such as office towers and hospitals.

How is commercial HVAC different from residential HVAC?

Commercial and residential HVAC systems share similarities but also have key differences:
  • Size and Capacity: Commercial HVAC systems are usually much larger than residential systems to handle greater heating and cooling demands of bigger spaces.
  • Complexity: Commercial HVAC systems are more complex, often using multiple units, zones, and advanced controls.
  • Ductwork: Commercial ductwork is typically more extensive and complex than residential ductwork.
  • Refrigerant: Commercial systems may use different types of refrigerant than those used in residential systems.
  • Maintenance Requirements: Regular maintenance is essential for both types of systems, but commercial systems typically require more frequent and specialized maintenance.
  • Cost: Commercial HVAC installation and maintenance costs are generally higher than residential due to system complexity and specialized labor required.

When should I consider upgrading my commercial HVAC system?

Consider a commercial HVAC upgrade if:
  • Age: If your system is nearing the end of its typical lifespan, it is likely to be less efficient and more prone to breakdowns.
  • Frequent Repairs: Frequent repairs can be an indicator that your system is nearing the end of its useful life.
  • Rising Energy Bills: An inefficient system can lead to increased energy consumption.
  • Inconsistent Temperatures: If some areas of your building are too hot or too cold, an upgrade might be necessary.
  • Poor Indoor Air Quality: Upgrade to an HVAC system with enhanced filtration for improved IAQ.
  • Refrigerant Changes: If your system uses an outdated refrigerant that is being phased out, an upgrade might be required to comply with new regulations.
A new, energy-efficient HVAC system can significantly improve your business's bottom line by reducing energy consumption.

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 conditions and circulates air throughout the building. 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 used to absorb heat from indoor air, providing efficient cooling for large spaces. They are typically more energy-efficient for large cooling applications compared to standard air-cooled AC units.

How is commercial HVAC different from residential HVAC?

Key differences between commercial and residential HVAC include:
  • Size and Capacity: Commercial HVAC systems are usually much larger than residential systems to handle greater heating and cooling demands of bigger spaces.
  • Complexity: Commercial HVAC systems are more complex, often using multiple units, zones, and advanced controls.
  • Ductwork: Commercial ductwork is typically more extensive and complex than residential ductwork.
  • Refrigerant: Commercial systems may use different types of refrigerant than those used in residential systems.
  • Maintenance Requirements: Regular maintenance is essential for both types of systems, but commercial systems typically require more frequent and specialized maintenance.
  • Cost: Commercial HVAC installation and maintenance costs are generally higher than residential due to system complexity and specialized labor required.

When should I consider upgrading my commercial HVAC system?

Consider a commercial HVAC upgrade if:
  • Age: If your system is 15-20 years old or older, it is likely to be less efficient and more prone to breakdowns.
  • Frequent Repairs: If you're constantly calling for repairs, a new system may be more cost-effective in the long run.
  • Rising Energy Bills: An inefficient system can lead to increased energy consumption.
  • Inconsistent Temperatures: Uneven temperatures can be a sign of an improperly sized or poorly maintained HVAC system.
  • Poor Indoor Air Quality: Upgrade to an HVAC system with enhanced filtration for improved IAQ.
  • Refrigerant Changes: If your system uses an outdated refrigerant that is being phased out, an upgrade might be required to switch to an environmentally friendly refrigerant.
A new, energy-efficient HVAC system can significantly improve your business's comfort and reduce operating costs.
