Commercial Air Conditioning in Berlin

The ArbStättV (Workplace Ordinance) and ASR A3.6 prescribe minimum air-exchange rates (typically 30–50 m³/h per person), temperature range (20–26 °C in winter) and humidity (30–70 %). Server rooms, medical practices, dental clinics and restaurant kitchens have additional regulations with higher air-change rates. We check the building type, usable area and create a compliant air-conditioning concept – with documentation for workplace safety authorities.

Yes – that's standard for us! Many Berlin commercial spaces don't allow installation during opening hours. We plan and execute installations in the evening (after 6 pm), weekends (Friday–Sunday) or overnight. This requires good coordination – we bring site lighting and barriers. Thus you avoid operational disruptions completely.

Yes – with annual contract we handle regular filter changes (monthly to half-yearly depending on fouling), refrigerant checks, heat-exchanger cleaning and annual system inspection per EN 13779. For contract customers we guarantee response time under 4 hours for breakdowns (24/7). Costs typically €500–1,000/year for smaller systems, €1,000–1,875 for larger VRF systems.

A 200 m² office with moderate cooling demand (10–15 W/m²) typically requires a 4–5 kW VRF system or multi-split installation. Costs: Units €10,000–15,000, installation and refrigerant piping €5,000–7,500, fresh-air supply and ducts depending on location €3,750–10,000. Total about €18,750–32,500. Add: power connection (possibly new hookup), building permits (Berlin), old system disposal (€625–1,875). Maintenance ~€750/year. Payback period through energy savings typically 8–12 years.

For restaurants and gastronomy a central system with fresh-air supply (per DIN 18017 gastro standard) is better: kitchens generate heat surges and strong odour loads – split systems can't handle this properly. A central ventilation and air-conditioning system with exhaust air cleaning (carbon filters) is more hygienic, efficient and meets all hygiene and workplace requirements. Costs €31,250–62,500 depending on restaurant size. On-site consultation required – we bring ventilation sketches.

That depends on size and location. Small split systems (up to 12 kW) typically don't need building permits. Larger systems (>12 kW) or central ventilation can be permit-required, especially in listed buildings. Workplace systems must be reported to workplace safety authorities. Noise protection regulations often cover outdoor units. We check this for you: we obtain permits if needed and coordinate with authorities. Cost: €625–2,500 depending on complexity.
