01 / 5About us
We do more than install HVAC systems — we build long-term partnerships.
Reliability, engineering expertise and uncompromising quality since day one.
01 — Our story
From Sarajevo's engineering tradition to Europe's construction sites.
ASG Klimatechnik Kft was established in Budapest in 2021, at a time when the European construction industry was adapting to the new demands and operational challenges that followed the COVID-19 pandemic. The objective was clear from the start: deliver high-quality HVAC engineering, installation and maintenance without compromise.
We build on the extensive experience of our engineering team and the strength of trusted strategic partners — including our partner group in Sarajevo, a leading company in HVAC and fire protection systems in Bosnia and Herzegovina with decades of experience across European markets.
Today our portfolio includes the construction, refurbishment and maintenance of HVAC systems in some of Budapest's most recognized commercial developments — and premium retail stores across the continent for one of the world's most demanding clients: Inditex.
The trust placed in us by internationally recognized clients and global brands is the strongest confirmation of our professionalism and consistent commitment to excellence.
