Heating, cooling, water supply and ventilation from a team that learned what precise construction really means on industrial projects, under penalty clauses and strict technical supervisors. We now bring that same discipline to your condominium project or your home.
I'm Márk Istenes, founder and owner of Istenes Épületgépészet Kft. Early in my career I spent years running large-scale industrial projects for one of Hungary's largest general contractors, with a building services engineering degree from the Faculty of Engineering and Information Technology at the University of Pécs behind me.
In industrial construction there's no room for excuses: penalty clauses, strict technical supervisors and precise plans rule everything. When I founded my own company, I brought that same uncompromising organization and engineering discipline into the residential and condominium sector. Our team is young and digitally fluent, yet understands and reads even the most complex construction drawings.
Our team and philosophyCentral plant rooms, risers and per-unit individual metering and control, with seamless regulatory approval and flawless handover documentation — for developers who can't afford delays.
Condominium solutions →Heat-pump heating/cooling, underfloor heating and heat-recovery ventilation for new builds; gas boiler replacement, complete water/drainage renovation and bathroom reconstruction for existing homes, with clean, tidy execution.
Residential services →Complete mechanical systems for halls, warehouses and office buildings: heating/cooling and VRV/VRF systems, industrial ventilation, vacuum rainwater drainage and compressed-air system installation.
Industrial solutions →A 10-unit condominium or a single-room renovation — with us it comes with the same discipline and paperwork as an industrial project.
You won't have to chase us by phone. We communicate digitally, respond quickly, and keep the site diary up to date every day.
We select and install the best-quality systems and materials tailored to your needs and the project's budget.
We organized our team so we can respond immediately in Budaörs, Érd, Dunakeszi, Szentendre, Gödöllő and the capital.
On request we prepare the mechanical design together with a design office we work closely with, so there are no issues with the plans during construction — the project stays in one hand from design to handover.
Before we take on the mechanical systems of homes and condominiums, large corporations and general contractors tested us on live projects with penalty clauses. Some of our references:
Price always depends on the size of the house, the chosen system (heat pump, gas boiler, surface heating) and the technical scope, so a fixed price would be irresponsible to quote. Send us your plans or ideas and we'll prepare a transparent, itemized quote — the request is free and comes with no obligation.
We work in Budapest and within a 1-hour radius of the capital, including Budaörs, Érd, Dunakeszi, Szentendre, Gödöllő and Szigetszentmiklós. Our team and logistics are specifically organized to respond quickly across this area.
On request we also prepare the mechanical design, together with a design office we work closely with. This means there are no issues with the plans during construction: the project stays in one hand from design to handover.
We contact you within 2 business days of receiving your request. The time to prepare the quote depends on the size of the project; with a detailed construction plan we can typically give an accurate, itemized price faster.
For most new houses, an air-to-water heat pump combined with surface heating (underfloor, wall or ceiling) is the most economical choice, since it delivers even comfort even at low flow temperatures. The final decision should always be based on the house's heat-loss calculation and your lifestyle — we help with that.
We provide complete handover documentation: pressure-test records, declarations of conformity and equipment manuals, ready to use immediately for the occupancy permit. We know exactly how much a delay can cost financially, so keeping to the schedule is a basic requirement for us.
Yes. You can count on us for extensions, alterations, new water or drainage connections, and unexpected mechanical faults. For us, a smaller job doesn't mean less attention — you get the same quality and tidiness.
