What Are Ceiling Cassette Heat Pumps?
Professional installation of ceiling cassette heat pump systems throughout Papatoetoe and South Auckland. Units mount flush in ceiling with only a decorative grille visible, providing 360-degree air distribution without using wall space.
Ceiling cassettes suit open-plan areas, commercial spaces, and homes where wall-mounted units would interfere with interior design or furniture placement. Ideal for areas requiring even temperature distribution across large spaces.
How Ceiling Cassettes Work
The indoor unit installs in the ceiling cavity with the visible grille sitting flush with the ceiling surface. Unlike high wall units that direct air in one direction, cassettes distribute air through vents on all four sides.
Key components:
- Ceiling-mounted indoor unit (installed in cavity)
- Outdoor heat pump unit
- Refrigerant piping between units
- Electrical connections and controls
- Condensate drainage system
- Wireless remote control or wall controller
The outdoor unit operates identically to standard heat pump systems, with the primary difference being the ceiling-mounted indoor component and 360-degree airflow pattern.

Pricing and Applications
Ceiling cassette pricing varies based on capacity, brand, installation complexity, and ceiling access requirements.
Typical pricing for Papatoetoe installations:
- Small cassette (2.5-3.5kW): $3,500-$5,000
- Medium cassette (5-7kW): $4,500-$6,500

Pricing includes standard installation with accessible ceiling cavity. Additional costs may apply for structural modifications, difficult access, or building consent requirements.
When Ceiling Cassettes Make Sense
Best applications:
- Open-plan living areas requiring even heating
- Commercial spaces (offices, retail, medical)
- Homes where wall space is limited or valuable
- Areas with high ceilings where wall units struggle
- Properties requiring discreet climate control
Installation requirements:
- Minimum 300mm ceiling cavity height
- Accessible ceiling space for unit and services

Ceiling Cassette vs. Wall-Mounted Units
Cassette advantages:
- No wall space required
- 360-degree airflow for even temperature
- Flush ceiling installation (minimal visual impact)
- Better air distribution in large or open-plan spaces
- Quieter operation (unit in ceiling cavity)
Cassette limitations:
- Higher installation cost than wall units
- Requires adequate ceiling cavity access
- More complex installation process
- Maintenance requires ceiling access
- Building consent may be required for ceiling modifications
For standard residential rooms without ceiling access, high wall heat pumps starting from $2,500 are more cost-effective.
