Hitachi System Free High Efficiency 4-Way Standard Cassette Indoor Unit FAQs
What is a 4-way cassette unit?
A 4-way cassette provides even air distribution in four directions, ensuring balanced comfort across larger spaces such as offices and shops.
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.
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.
How energy efficient are modern air conditioning and heat pump systems?
Modern HVAC systems achieve high seasonal efficiency ratings - SEER (Seasonal Energy Efficiency Ratio) and SCOP (Seasonal Coefficient of Performance), lowering running costs compared to older units while reducing carbon emissions.
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.
