Can I get a ceiling cassette heat pump installed in an existing home?

Yes, but the ceiling cavity needs to be checked first. The indoor unit needs enough space above the ceiling lining and a route for the refrigerant pipe. Most Central Auckland homes have adequate ceiling space. Gary confirms on the site visit.

What is the difference between a ceiling cassette and a ducted heat pump?

A ceiling cassette is a single unit recessed into the ceiling of one room with four-way airflow. A ducted system uses a central unit with ductwork running to multiple rooms throughout the home. A cassette costs much less than a full ducted system and covers one large room or zone very effectively.

How much does a ceiling cassette heat pump cost in Mt Eden?

Ceiling cassette installations in Mt Eden run from $4,500 for a medium space up to $9,000 or more for commercial or complex installs. All prices include supply, ceiling access work, installation and electrical connections.

What Is a Ceiling Cassette and When Does It Make Sense?

A ceiling cassette heat pump is recessed into the ceiling with only a flat grille visible from below. The indoor unit sits in the ceiling cavity above, connected by refrigerant pipe to the outdoor unit outside. Air is drawn in from the centre of the grille and pushed out in four directions simultaneously.

This four-way airflow is what makes a ceiling cassette the right choice for large, open or square-shaped rooms where a high wall unit would struggle to reach all four corners evenly. The specialist I recommend will confirm in the site visit whether your ceiling space can accommodate one.

Where Ceiling Cassettes Work in Central Auckland

The specialist I recommend installs ceiling cassettes in three main situations across Mt Eden and Central Auckland.

Large open plan living and kitchen

The most common ceiling cassette install in Central Auckland. Renovated villas and newer homes in Mt Eden, Kingsland and Sandringham often have large open plan kitchen and living areas that are 50m2 or more. A single ceiling cassette positioned in the centre of the space covers all four corners in a way no wall-mounted unit can match.

Commercial spaces and offices

Retail stores, medical practices, offices and reception areas across Central Auckland frequently use ceiling cassettes. In a commercial environment you can't have wall units taking up display or desk space, and the ceiling is the natural place for heating and cooling equipment.

New builds and renovations

The best time to put a ceiling cassette in is during a new build or renovation when the ceiling is open and the unit can be positioned and connected before the gib goes on. My Mt Eden specialist works with builders across Central Auckland to plan cassette installations into new builds from the start.

Gary's tip

Don't wait until the gib is on. If you're doing a reno, tell your builder to leave the ceiling open where the cassette is going. It takes a fraction of the time and saves a significant amount on the install cost.

My Mt Eden specialist installs Panasonic, Mitsubishi Electric and Daikin ceiling cassettes, the three brands with the strongest track records for this unit type in NZ. Ceiling cassettes cost more than high wall units because of the ceiling access work involved. In an existing home he needs to work in the ceiling cavity to position and connect the unit, which takes longer than a standard wall-mount install. The only accurate price is a fixed-price quote after he has seen your ceiling space. Visit the main heat pump installation page or read the full heat pump installation cost guide or use the sizing calculator for a rough estimate first.

Ceiling Cassette vs Ducted vs High Wall

All three hide or partially hide the indoor unit. Here is the honest difference between them.

Ceiling Cassette Questions We Get Asked All the Time

Can I get a ceiling cassette installed in an existing home?

Yes, but the ceiling cavity needs to be checked first. The indoor unit needs enough space above the ceiling lining to sit flush, and there needs to be a route for the refrigerant pipe to reach the outdoor unit. Most Central Auckland homes have enough ceiling space for a cassette install. My Mt Eden specialist confirms this on the site visit and won't quote until he's seen the ceiling himself. Getting the size right matters, an undersized unit runs flat out and costs more to run, while an oversized unit short-cycles and wears out faster. He does a proper heat load calculation on every cassette install.

Why is a ceiling cassette better than a high wall for a large open plan space?

A high wall unit pushes air in one direction. In a large open plan kitchen and living area that might be 60m2 or more, the far corners of the room simply don't get enough airflow. A ceiling cassette positioned in the centre of the space pushes air in all four directions simultaneously, covering the entire room evenly from a single unit. It's the difference between the room feeling consistently warm and having warm and cold patches.

Is a ceiling cassette the same as ducted?

No. A ceiling cassette is a single unit recessed into the ceiling of one room. A ducted system uses a central unit in the ceiling with ductwork running to multiple rooms throughout the home. A cassette is much cheaper than a full ducted system and covers one room or zone very well. If you want whole-home heating and cooling with ceiling vents in every room, ducted is the right answer. Gary will help you work out which suits your home on the site visit. Read more on the ducted heat pump page.

Do I need a council permit?

Usually no. Standard ceiling cassette installations are a permitted activity under Auckland Council rules as long as the outdoor unit placement doesn't breach boundary setbacks or create unreasonable noise for neighbours. Gary handles the placement to keep you compliant and will flag anything unusual during the site visit.

Can a ceiling cassette connect to a multi-room outdoor unit?

Yes. A ceiling cassette can be one of the indoor heads connected to a multi-room outdoor unit. This means you could have a cassette in the open plan living area and high wall units in the bedrooms, all running off a single outdoor compressor. Gary will design the right system for your home on the site visit. Read more on the multi-room heat pump page.
