Airconditioning
An air conditioner is used for comfortable cooling and often also for energy-efficient heating of one or more rooms. Depending on the installation, you can choose a single split air conditioner, multi split system, separate indoor unit, separate outdoor unit or a complete air conditioning combination.
At Hewa, you will find air conditioners for homes, offices, workshops, retail spaces and business projects. When selecting the right system, check cooling capacity, heating capacity, BTU output, room volume, pipe length, sound level, mounting position, indoor unit choice and the technical match with the outdoor unit.

Air conditioners for cooling, heating and comfort control
Air conditioners are used to cool rooms in a controlled way and, depending on the system, also to heat efficiently. A well-selected air conditioning system provides stable temperature control, suitable air distribution and comfort in homes, offices, retail spaces, workshops and technical rooms.
Selecting an air conditioner
The right air conditioner depends on room volume, insulation, solar load, usage profile, required control options and technical installation possibilities. For one room, a single split air conditioner is often selected. For multiple rooms, a multi split solution may be suitable, combining several indoor units with one outdoor unit.
Within this category, also review single split air conditioners for one room, multi split air conditioners for multiple rooms and air conditioner indoor units for wall mounting.
Important when choosing air conditioners
- Match cooling capacity and heating capacity to room volume and heat load
- Choose between single split, multi split, separate indoor units or separate outdoor units
- Check BTU capacity, energy label, sound level and air distribution
- Check maximum pipe length, height difference and technical combination options
- Check mounting position, condensate drain, electrical connection and isolator switch
- Consider service access, vibration damping and outdoor unit placement
- Have refrigerant work carried out by a qualified F-gas technician
Applications within air conditioning
Living spaces
For comfortable cooling and additional heating in living rooms, bedrooms, home offices or apartments.
Office and retail
For stable temperature control in rooms where comfort, sound level and air distribution are important.
Project installations
For installations where multiple rooms, indoor units, outdoor units and pipe routes need to be technically coordinated.
Indoor unit, outdoor unit and system combination
With air conditioners, the technical combination between indoor unit and outdoor unit determines system performance. A single split set consists of one indoor unit and one outdoor unit. In multi split systems, several indoor units are combined with one outdoor unit, where total capacity, pipe lengths and permitted combinations must be checked carefully.
For installers, installation quality and system matching are especially important. This includes correct sizing, stable outdoor unit placement, insulated refrigerant pipework, neat trunking, proper condensate drainage, correct electrical connection and sufficient service space. A carefully installed air conditioner helps prevent noise issues, leakage, efficiency loss and unnecessary service problems.
Frequently asked questions about air conditioners
Which air conditioner do I need?
The right air conditioner depends on room volume, insulation, heat load, number of rooms, required control options and installation location. Single split is often suitable for one room; multi split can be suitable for multiple rooms.
What is the difference between single split and multi split?
A single split air conditioner consists of one indoor unit and one outdoor unit for one room. A multi split air conditioner uses one outdoor unit with multiple indoor units for several rooms.
Can an air conditioner also heat?
Many modern air conditioners can heat as well as cool. Check heating capacity, efficiency, operating range and desired performance at low outdoor temperatures for each model.
Where should an outdoor unit be installed?
An outdoor unit must be installed firmly, with low vibration and good service access. Consider sound, airflow, free space, condensate drainage, pipe length and distance from neighbours or occupied areas.
Who may install an air conditioner?
Refrigerant work on split air conditioners must be carried out by a qualified F-gas technician. Electrical connection and safety protection must also comply with the technical requirements.
