The main air conditioning types
There are many types of air conditioning systems available today, each offering unique benefits in terms of cooling efficiency, flexibility, and installation requirements.
The systems most commonly used include:
- Split Systems
- Multi-Split Systems
- Mini VRF Heat Pumps
- VRF Heat Recovery Systems
- Ceiling Cassette Systems
- Ducted Air Conditioning Systems
Understanding how each one works will help you select the ideal setup for your space.
Split air conditioners
A split system is one of the most popular air conditioner options for both homes and small offices. It consists of two main components: an indoor unit that delivers cool air and an outdoor unit that expels heat. The indoor unit is typically mounted on a wall or ceiling, while the outdoor unit is placed outside the building.
The refrigeration cycle begins when warm indoor air passes over cold evaporator coils, where heat is absorbed and transferred to the external unit. This results in a steady stream of cold air flow circulating indoors.
Benefits of split AC systems
- Compact and quiet operation
- Energy-efficient cooling and heating
- Improved indoor air quality through built-in filters
- Easy installation and low maintenance
- Ideal for homes, offices, and small retail spaces
Multi split air conditioning systems
Multi-split systems connect multiple indoor units to a single outdoor unit, allowing individual temperature control across different rooms or zones.
Each indoor unit operates independently, providing personalised comfort while maximising energy efficiency by cooling only occupied areas.
Benefits of multi-split systems
- Independent temperature control per room
- Energy savings from zoned cooling and heating
- Space-saving outdoor setup
- Excellent for larger homes, offices, or commercial buildings
Mini VRF heat pump
Mini VRF heat pump systems offer the same advanced technology as commercial VRF systems but on a smaller scale. They use variable refrigerant flow to adjust output based on demand, optimising cooling efficiency and comfort.
These compact yet powerful AC units deliver both heating and cooling from a single outdoor unit, ideal for buildings with limited space.
Benefits of mini VRF systems
- High energy efficiency with adaptive performance
- Compact outdoor units, perfect for small spaces
- Provides both heating and cooling from one system
- Ideal for apartments, small offices, or medium-sized properties
VRF heat recovery
VRF heat recovery systems are among the most advanced air conditioners, capable of simultaneously heating and cooling different zones within a building.
They achieve this by recycling excess heat from one area and transferring it to another that requires heating, making them exceptionally efficient and environmentally friendly.
Benefits of VRF heat recovery systems
- Up to 60% energy savings through heat recovery
- Simultaneous heating and cooling across multiple zones
- Highly flexible and scalable for large installations
- Perfect for offices, hotels, schools, and multi-storey commercial buildings
Ceiling cassette air conditioner units
Ceiling cassette systems are designed to blend seamlessly with modern interiors. Installed flush within the ceiling, they distribute cold air evenly in four directions, ensuring consistent comfort throughout the space.
Their discreet design and quiet performance make them particularly suitable for environments where both aesthetics and comfort matter.
Benefits of ceiling cassette systems
- Sleek, unobtrusive installation within ceilings
- 360-degree air distribution for balanced cooling
- Quiet operation, perfect for customer-facing spaces
- Ideal for open-plan offices, restaurants, schools, and retail stores
Ducted air conditioning systems
Ducted systems provide the ultimate discreet, centralised air conditioning. Air is distributed through concealed ducts installed in ceilings or walls, creating uniform comfort across every room without visible indoor units.
These systems are popular in large homes, offices, and luxury properties, offering powerful performance and seamless aesthetics.
Benefits of ducted air conditioners
- Invisible design with concealed vents
- Consistent temperature across multiple rooms
- Compatible with smart home and zoning controls
- Best for large residential and commercial properties
How to choose the right air conditioning unit
Selecting the ideal system depends on several key factors:
- The size and layout of your property
- The number of rooms and level of individual control required
- Your energy efficiency and budget goals
- Any specific needs, such as noise control or humidity management
Our team at Mechcool can assess your property and recommend the most effective and economical solution tailored to your exact requirements.
