Air conditioning and ventilation for indoor comfort

Air conditioning and ventilation together provide temperature control, air circulation and air exchange in homes, offices, workshops and technical rooms. Within this category, you will find climate solutions for cooling, heating, ventilation and technically correct installation of air conditioning systems.

Selecting air conditioning and ventilation

The right solution depends on the room, required comfort, heat load, usage profile and technical installation options. An air conditioner is mainly selected for cooling and often also heating, while ventilation focuses on air exchange, air quality and moisture removal.

Within this category, also review air conditioners for cooling and heating, ventilation for air exchange and air conditioning installation material.

Important when choosing climate solutions

  • Match cooling capacity and heating capacity to room volume and heat load
  • Check whether single split, multi split or separate indoor and outdoor units are suitable
  • Check sound level, energy consumption, air distribution and mounting position
  • Check refrigerant pipe length, condensate drain, electrical connection and isolator switch
  • Select ventilation based on airflow, room function, air extraction and duct route
  • Use suitable mounting material, trunking, fittings and insulated refrigerant pipework
  • Have F-gas work and electrical connection carried out by qualified professionals

Applications within air conditioning and ventilation

Homes and apartments

For comfortable cooling, additional heating and air exchange in living rooms, bedrooms, home offices and renovation projects.

Office and retail spaces

For a stable indoor climate in spaces where comfort, sound level, air distribution and operational reliability are important.

Technical and business projects

For installations where air conditioning, ventilation and mounting material are combined project-wise with clear requirements for placement and maintenance.

System layout, installation and air distribution

A good air conditioning or ventilation system starts with correct sizing. With air conditioners, indoor unit, outdoor unit, refrigerant pipework, condensate drain and electrical connection must technically match. With ventilation, airflow, duct diameter, grille position and pressure loss are important points. An incorrectly selected system can cause draughts, noise, insufficient cooling or poor air exchange.

For installers, installation quality is also important. This includes correct outdoor unit placement, vibration-reduced mounting, clean pipe routes, proper condensate drainage, service access and enough free space around the unit. For ventilation, air extraction, air supply, roof terminals, ventilation grilles and maintenance of filters or ducts must also be considered.

Frequently asked questions about air conditioning and ventilation

What is included in air conditioning and ventilation?

This includes air conditioning systems, single split air conditioners, multi split air conditioners, indoor units, outdoor units, ventilation solutions and installation material for mounting, connection and finishing.

What is the difference between air conditioning and ventilation?

An air conditioner mainly controls temperature by cooling and often also heating. Ventilation provides air exchange, moisture removal and improved indoor air quality.

When should I choose a single split air conditioner?

A single split air conditioner is suitable when one room needs cooling or heating. The system consists of one indoor unit and one outdoor unit serving one climate zone.

When is a multi split air conditioner useful?

A multi split air conditioner is useful when several rooms need to be controlled separately with one outdoor unit and multiple indoor units. Total capacity, pipe lengths and combination options must be checked carefully.

What should an installer check during installation?

Check cooling capacity, pipe length, condensate drain, electrical connection, outdoor unit position, vibration damping, sound level, air distribution, ventilation capacity and the technical documentation of all components.
