Hitachi Light Commercial R32 Ducted Indoor Unit FAQs

What is a ducted indoor unit?
Ducted indoor units are concealed within ceilings or walls, distributing air through ducts. They’re ideal for spaces that require discreet installation and uniform airflow.
What is R32 refrigerant and why is it used in HVAC systems?
R32 is a next-generation refrigerant with lower global warming potential (GWP) than older gases such as R410A. It delivers high efficiency while helping reduce environmental impact, making it a popular choice for modern heat pumps and air conditioning units in the UK.
What’s the difference between an indoor and outdoor unit?
Outdoor units house the compressor and release or absorb heat, while indoor units distribute conditioned air into the building. Together, they form a complete HVAC system.
Can HVAC systems help improve air quality?
Yes. Many units include advanced filtration that removes dust, allergens, and pollutants, contributing to a healthier indoor environment.
Are HVAC systems noisy?
Modern indoor units are designed for quiet operation, with sound levels often comparable to a whisper, making them suitable for bedrooms and offices.
What size HVAC unit do I need?
Sizing depends on room dimensions, insulation, occupancy, and usage. Oversized or undersized systems waste energy and reduce comfort - a qualified installer should calculate the correct capacity. Contact us at The MEP Shop today and we can help you size up your project correctly.
