Installation, start-up and training in the operation of air handling systems. We are technically able to solve spaces with any requirements. Family and apartment houses, office premises, industrial buildings including clean rooms, hospitals, banks, etc.

Recuperation = heat recovery. A home heat recovery unit brings in fresh air from outside and heats it with heat energy recovered from the waste air of the building. This results in large savings in the energy needed for heating. The two air streams are perfectly separated so that odours from the exhaust air do not penetrate into the supply air. Heat exchangers achieve high heat transfer efficiencies, typically around 90%.

In cooperation with established contractors, we provide complete implementation of technical building equipment (HVAC) – heating, measurement and control, medical installations.

Air conditioning

We can advise you on the right type and performance of air conditioning for your house or apartment. We provide complete turnkey deliveries, including professional installation, necessary construction work and warranty and post-warranty service.

Heat pumps

Replace your existing electric boiler, gas boiler or solid fuel boiler with an environmentally friendly and efficient heat pump.

We will design a suitable solution, select the optimal performance and take care of all subsidies for replacing existing sources or reducing energy consumption.

For the replacement of an older heat source with a heat pump, you can currently claim 80-180 CZK – depending on the type of original source and the amount of your annual income.


The maintenance interval for filter replacement is approx. 3 months, i.e. 4 times per year. This interval can be extended up to two or three times, provided pre-filters are used for outside air intake. It can be reduced by up to half for systems exposed to extreme dust loads (intake near roads, industrial buildings, etc.).

We supply filters for ventilation systems from DELBAG, Atrea, Systemair, Elektrodesign.

We can replace filter fabrics, filter inserts, pocket filters and HEPA filters.


Condition inspection, repair and renovation of HVAC systems and their parts. We carry out the replacement of filters and propose the technical optimisation of HVAC systems according to the evolving needs of our customers.

Based on a service contract, we can guarantee HVAC service within 24 hours of reporting a malfunction.
