Air conditioning from a specialist with certified refrigerant handling.

Split and multi-split systems for homes, offices, practices and server rooms – installation, refrigerant circuit, electrical work and maintenance from one source. A dedicated division since 2024.

Air conditioning is often installed by two companies: one mounts the units, the other comes for the power connection. With us one team does both – with a refrigerant handling certificate and an electrical contractor in-house. That saves an appointment and an interface.

Since 2024 air conditioning and refrigeration has been a dedicated division at HD-Überwachung. The focus is on split and multi-split systems for living rooms, offices, practices, hotel rooms and server rooms – and on combining them with solar PV so that summer cooling runs on your own electricity.

Scope

What we do in air conditioning

Split and multi-split systems

  • Wall units, floor consoles, cassettes for homes, offices, practices
  • Multi-split for several rooms on one outdoor unit
  • Quiet outdoor units, placed with neighbours and appearance in mind

Server rooms and technical rooms

  • Precise cooling for server rooms and plant rooms
  • Redundancy and temperature monitoring with alarm
  • Integration with building or alarm systems

Refrigerant circuit

  • Refrigerant circuit work with certified personnel
  • Leak testing, evacuation, charging, recovery
  • Documentation under the F-gas regulation

Electrical included

  • Supply line, protection, registration – by our own electrical contractor
  • Combination with PV: cooling with your own power
  • Control via app or smart home

Maintenance and service

  • Annual maintenance, filter cleaning, leak testing
  • Fault service, repair, replacement
  • Maintenance contract combined with other trades

Heating with air conditioning

  • Air-to-air heat pump as supplementary heating in spring and autumn
  • Efficient for attics, extensions, garden rooms, workshops
  • Advice on combining with the existing heating

Refrigerants R32 and R290

Current units run on R32 or increasingly propane (R290). Both place requirements on location and installation. We choose the unit by room, pipe length and regulation – not by what is in stock.

How it works

How an AC installation runs with us

Cooling load and location

Quote

Units, pipe routes, condensate drain, electrical work and commissioning at a fixed price.

Installation

Usually one day per system: core drilling, pipework, units, vacuum, charging, electrical connection.

FAQ

What customers ask us about air conditioning

Do I need a permit for the outdoor unit?

Usually not, but distance rules and noise limits apply (German TA Lärm). In rented flats you need the owner's consent. We advise on the location.

How often does air conditioning need maintenance?

Once a year: filters, heat exchanger, condensate drain, leak test, electrical check. For larger charges the F-gas regulation requires leak testing.

R32 or R290 – which is better?

R290 has a very low global warming potential but higher requirements for placement and pipe routing. We choose by installation situation – both are standard with us.

Can the air conditioner heat too?

Yes, modern split units are air-to-air heat pumps and heat very efficiently in spring and autumn. For attics, extensions or workshops often the most economical solution.
