What is an air conditioner without an outdoor unit?
Air conditioners without an outdoor unit are a smart solution for heating and cooling your home. This type of air conditioner has only one unit and no additional outdoor unit. All the components needed to cool and keep your room comfortable are integrated into this single indoor unit. This type of air conditioner is also known as a monoblock air conditioning. Monoblock air conditioners can be either mobile or fixed, although fixed air conditioners without an outdoor unit are often more efficient in both cooling and, if possible, heating.
How does an air conditioner without an outdoor unit work?
This air conditioner works in the same way as traditional systems, but without the need for an outdoor unit. The process is as follows:
- Coolant is compressed: The compressor compresses the coolant, raising the temperature.
- Heat output: The heat generated is distributed into the room via a heat exchanger and fan through a grille at the top of the unit.
- Cooling: After compression, the coolant expands, causing it to cool.
- Heat Recovery: The cooled liquid flows through the evaporator, which uses a fan to draw heat from the outside air.
This process repeats continuously, alternately compressing and expelling the refrigerant, producing hot or cold air. Unlike traditional systems with separate indoor and outdoor units, the air conditioner without an outdoor unit performs everything within one wall-mounted unit.

What are the advantages of an air conditioner without an outdoor unit?
In addition to efficiently and effectively cooling your home, an air conditioner without an outdoor unit offers several advantages. Here are the main ones:
- You don't have to free up space on the outside of your home or office for an outdoor unit, which in all honesty isn't very pretty either. Instead of a large outdoor unit, the return air ducts are subtly routed through the wall and finished on the outside of the building with two stylish grilles.
- In addition, monoblock air conditioners often have a stylish and modern design, making them perfect for any interior.
- Furthermore, air conditioners without an outdoor unit are very easy to maintain. More itself, they are virtually maintenance-free, making a maintenance contract unnecessary.
- Also, mononoblocks are easy installation, as the models typically assume a plug-and-play system.
- Finally, a monoblock air conditioner is durable and uses very little energy, making them interesting for your energy bill as well. Most air conditioners without an outdoor unit have an energy class A+.
Are there any drawbacks?Â
Although an air conditioner without an outdoor unit has numerous advantages, it also has a disadvantage. Namely, this type of air conditioner makes a little more noise. The compressor and fans built into the unit are slightly louder than a convetional system where these components are placed outside
How do you install an air conditioner without an outdoor unit?
As mentioned above, an air conditioner without an outdoor unit is quite straightforward to install. In fact, it is definitely possible to install an air conditioner yourself. If you purchase an air conditioner through Aquaconsult and wish to install it yourself, you will receive all the information in a manual where everything is clearly explained.
Where best to place these?
There are two places in a home that are most commonly used for an air conditioner without an outdoor unit. One of those places is the living room. After all, that is - normally - the room in the house where you spend the most time. With an air conditioner without an outdoor unit, you will have a pleasant, fresh living room in the summer and a cozy warm living room in the winter.
The second place is a bedroom. After all, there's nothing worse than a bedroom that's too hot in the summer or an icy cold bedroom in the winter. Thanks to the Innova Monoblock air conditioner, that's a thing of the past.
Also, can you use the air conditioner without an outdoor unit as a heater in winter as well?
Yes, you can! A monoblock air conditioner often works with a heat pump. That means this air conditioner can both cool and heat your home. This is a big advantage today, because thanks to its low energy consumption, your home can be energy efficient heating with an air conditioner.
How does a heat pump air conditioner work?
Although the name would not suggest it, a heat pump is not only used to heat a home. This technology is also used to cool a home. But how does it work?
Want to heat the room? Then a heat pump pulls cold air out of the room to heat it in the unit and then releases the air back into the room. Do you want to cool the room? Then the opposite happens. Our Innova Monoblock air conditioners work with this system.
How much does an air conditioner without an outdoor unit cost?
