Air conditioning
System types
Which system suits which building
- Split
- One outdoor unit, one indoor unit. The simplest and cheapest solution for a single room, such as a bedroom or a small office.
- Multi-split
- One outdoor unit serves several indoor units. Useful where several rooms need cooling but there is only one place for the outdoor unit. In Berlin's existing building stock that is the normal case.
- VRF
- For larger properties: many indoor units on one refrigerant circuit, individually controllable, with rooms cooled and heated at the same time. Typical for office floors and medical practices.
An air conditioner is two trades, not one
That is why it comes from one source here. Anyone qualified in only one of the two cannot fully commission the system.
- Refrigeration work
- Work on the refrigerant circuit requires a certificate of competence under the EU F-gas regulation. That covers routing and brazing the refrigerant lines, evacuation, charging and the leak test.
- Electrical connection
- A dedicated circuit, the right protection, often an extension in the distribution board. As a registered installation company we do that ourselves instead of coordinating a second contractor.
- Condensate and core drilling
- Every system produces condensate that has to be drained in a controlled way. Add to that core drilling for the lines and mounting the outdoor unit.
- Getting permission
- An outdoor unit on the facade or the balcony usually requires the consent of the owner or the owners' association. We say early on what is needed for that.
How it works
From enquiry to commissioning
Establish the cooling load
Room size, glazing, orientation, equipment and people in the room. Only then is it clear how large the system has to be. Oversized is as wrong as undersized.
On-site appointment
Where the outdoor unit can go, how the lines run, where the condensate drains, what the electrical side involves. After that the scope is fixed.
Quote
In writing, with system type, capacity and scope. Anything still depending on a consent is stated explicitly.
Installation and handover
Installation, evacuation, charging, leak test, commissioning and instruction. Documentation and system labelling are part of it.
For property managers
Maintenance is not optional
Air conditioners lose refrigerant over the years, filters clog, and performance drops before anyone notices. Above a certain charge, the F-gas regulation also requires regular leak testing. Which intervals apply to a specific system, we tell you after the survey.
For property managers that means one contact for the entire portfolio, test reports per property, and invoicing that can be allocated.

A photo of the system or the affected spot says more than a long description and usually saves an appointment.
