Guide values from our projects in Berlin, so you know what to expect before the first conversation. We quote the fixed price after the free on-site visit.
Split air-conditioning systems cool in summer and heat in winter – efficiently, quietly and at significantly lower running costs than older systems. In Berlin apartments and offices they are the most popular solution for climate comfort.
Controlled mechanical ventilation (KWL – Kontrollierte Wohnraumlüftung) with heat recovery provides continuously fresh air while saving up to 90 % of ventilation heat losses. It is standard in modern low-energy and passive houses – and increasingly popular in Berlin old-build properties too.
Decentralised ventilation units are the fast, affordable solution for individual rooms without an extensive duct network. Each unit requires only a small core-drilled hole in the outer wall.
Commercial buildings in Berlin have specific requirements for air-conditioning and ventilation: cooling loads from equipment and occupants, statutory requirements for workplaces and varying usage hours. We plan and install commercial air-conditioning technology for offices, medical practices, restaurants and retail premises.
Regular maintenance of ventilation and air-conditioning systems is not only important for efficiency – it is legally required for commercial installations and significantly extends their service life. We carry out annual maintenance for all air-conditioning and ventilation systems – residential and commercial alike.
All figures are guide values for typical Berlin buildings and do not replace a quote. We check which subsidies you can use in addition before you place the order.
A single-split system costs from €3,500 including installation, multi-split systems for three to four rooms from €9,375, and installation takes one to two days. For residential ventilation with heat recovery, expect €6,250 to €15,000; decentralised units cost €2,000 to €3,125 per pair.
In a rented flat you need the landlord's consent, in an owners' association a resolution of the WEG, because the facade is common property. In listed or protected areas we clarify the situation with the district office and plan location and noise so that neighbours are not disturbed.
Once a year in residential use, twice a year in commercial premises with hygiene requirements. Maintenance costs €150 to €250 per unit and covers filters, refrigerant check and condensate drain. For larger systems the F-gas regulation requires regular leak checks, which we document.
