Eco Vent provided commissioning service for MVHR system recently installed. The commitment by Lucas to ensure that the system was properly installed and balanced was excellent with the amount of time required to acchieve exacting results never an issue. For a high standard of workmanship I would highly recommend Eco Vent.
I highly recommend this company, they were quick to turn up, very efficient and Lucas did a great job, thanks
Really happy with the job this guy did in my warehouse. He sorted out the ventilation properly and the humidity has gone way down. You can actually feel the difference in the air. Quick, tidy, and didn’t cost a fortune. Would definitely recommend!
Eco Vent did a fantastic job! The ventilation works even better than I expected. The humidity in the house has dropped from 80% to 60% (most of the day it's below 60%). Now I have proper ventilation in my home, not just some holes in the walls that were supposed to serve as ventilation
Meet the Founder — Lucas Koc
Lucas
Founder, Lead Installer & Blog Author — Eco Vent Ireland
Hello, I’m Lucas — originally from Poland, now proudly based in Ireland, where I found my love, home, passions and my profession.
Privately, I’m passionate about new technologies and 3D interior design, which often influences the way I approach system planning, layout and the aesthetic integration of ventilation into a home’s architecture.
Before founding Eco Vent Ireland, my work revolved around metal fabrication, home renovations and carpentry. Those years gave me an engineer-minded approach: precision, structural awareness and discipline. And in ventilation — just like in joinery —
“Great results are always built from small, invisible details.”
I got into ventilation after dealing with a serious mould and humidity problem in my own newly bought house. That experience pushed me to complete the NZEB Ventilation Programme.
I saw how many homes were struggling with poor air quality, humidity, noise and badly-installed ductwork. I decided to specialise fully in ventilation so I could bring a higher standard of workmanship, proper system balancing, and clean, discreet finishes that most installers don’t offer.
10 Reasons Why You Should Choose Eco Vent Ireland
Choosing the right ventilation installer has a direct impact on your home’s comfort, energy efficiency and long-term health. At Eco Vent Ireland, every system is designed with precision, safety and durability at its core. My approach combines technical expertise, real-world experience and a genuine commitment to doing things the right way — with no shortcuts, ever. Here are ten reasons why homeowners across Leinster trust Eco Vent Ireland:
MY STORY
From Homeowner to Ventilation Specialist
My journey into ventilation began 4 years ago, when my wife and I bought our first home in Ireland.
Something shocked us immediately:
– no extract fans in the bathrooms
– an airtight home without any ventilation strategy
Previous owners wanted the house “more energy efficient”, but forgot that airtightness without purpose-provided ventilation simply traps moisture.
Ireland’s climate is humid. We quickly noticed condensation, stale air and the early signs of mould. As perfectionists I knew our home had to be a healthy place – not a breeding ground for moisture, bacteria and allergens.
NZEB Ventilation programme
Eventually, to solve the problem of poor ventilation in my house, I enrolled in the Irish NZEB Ventilation programme — and everything clicked.
The training gave me the technical foundation I needed to understand ventilation not just as a system, but as a balance of airflow, airtightness, building physics and user behaviour. The first home I “fixed” was my own.
I installed an MVHR system to address the humidity and ventilation problems we were experiencing.
Soon after, I helped friends fix their own humidity and ventilation issues.
My wife said:
“You should do this professionally.”
And Eco Vent Ireland was born.
Today, I combine technical precision with high level craftsmanship. I can run ductwork neatly, build custom enclosures, and finish everything to a high aesthetic standard that most installers don’t offer. My work is not only technically correct and fully compliant with Irish ventilation regulations —it also looks discreet, modern and professionally fitted.
Why I Respect Irish Building Regulations
One thing I admire about Irish Building Regulations is how all parts of the system support each other — ventilation, airtightness, fire safety, plumbing, energy performance. Nothing conflicts. Everything is synchronised. A perfect symbiosis.
Part F Building Regulations Ireland Example:
Irish Building Regulations — especially TGD Part F and Part L — are exceptionally well designed. During the calculation of the general airflow rate for a dwelling in Ireland, two scenarios must be considered:
1. Based on total floor area,
2. Based on the occupancy of the dwelling.
You calculate the value for each scenario and select the higher one as the starting point for the general airflow rate for the entire building.
Additionally, the system must have a minimum 25% extra capacity above this value. This reserve is essential for providing sufficient boost when needed — for example, during showers, cooking, or when guests visit and the number of occupants temporarily increases. Meeting these thresholds ensures compliance with TGD Part F (2019) and forms a strong foundation for creating a healthy indoor environment — but it is not an automatic 100% guarantee.
Actual indoor air quality also depends on:
- The condition of the building itself (insulation, airtightness, absence of thermal bridges).
- The quality of the outdoor air
- Correct installation and maintenance of the system
- User behaviour
- Controlling indoor pollution sources
My Installation Philosophy — Precision & No Shortcuts
“Think for 3 hours, work for 5 minutes.“
In my view, good ventilation work is 90% planning and 10% installing. When you carefully design every detail in advance, the installation itself becomes quick, accurate, and problem-free.
Real Examples — Why Planning Matter?
Want to see what happens when ventilation is installed without proper planning? Check the case studies below for real faults I encounter on Irish sites — and how they should have been done.
Rigid Ducts Wherever Possible
I avoid flexible ducting because it is not lifetime‑durable, it can be easily damaged during professional cleaning, it traps more dust, and it reduces overall performance. Irish building regulations reinforce this best practice: “Use of flexible ductwork should be avoided and should only be used in very short lengths.”
I also favour oversizing duct diameters wherever possible, as this significantly reduces airflow resistance and helps the system operate more quietly and efficiently.
Rigid ducts require planning, skill and proper insulation — especially around 90° and 45° bends. Creating insulation that fits these bends perfectly takes time and craftsmanship, which is why I prepare custom templates in my workshop before arriving on site. This ensures a perfect fit and avoids wasting time during installation. You can see a detailed look at this insulation process in our Heat Recovery Ventilation System Installation Gallery
Case Study: The Washing Machine Hose Condensate Trap
I once found a washing machine hose used as a condensate drain — loosely pushed onto a PVC pipe and located 20 cm from an electrical junction box. A small leak could have caused serious damage. This is why proper installation matters.
Case Study: Missing Duct Insulation
Missing insulation on cold duct sections is common. This causes heat loss, reduced heat recovery efficiency and condensation risks. Insulation is not optional — it’s a core requirement of Part F.
Designing Systems for Future Maintenance
Good ventilation systems must be installed in a way that allows safe and practical maintenance in the future. When installing systems in attic spaces, I always build a small section of flooring first — free of charge — to ensure safe access for myself and for anyone who services the system in the years ahead. This simple step greatly improves safety and long‑term maintainability of the installation.
My years of experience in renovations also allow me to design duct routes in a way that makes it easy to conceal them later without affecting the existing look of the rooms. A ventilation installation can even be an opportunity to refresh the interior — because a simple, well‑executed duct concealment can add character and clean lines to an otherwise plain space. See our ductwork concealment photo gallery
Why Building Diagnostics Matter
Before selecting or assessing any mechanical ventilation system, it is important to understand how the building actually performs. Knowing the building energy rating, the overall airtightness and the quality of insulation gives a clearer picture of how effective the chosen system will be.
The most reliable method of assessing airtightness is the blower door test — it provides measurable data about how much air escapes through the building envelope. Thermal imaging can also be extremely useful, especially for identifying simple issues such as insulation that doesn’t sit tightly against the ceiling or rafters. These gaps create cold spots (thermal bridges) which can lead to condensation and mould.
Most of these defects can be fixed in just a few minutes, yet they can significantly impact the home’s overall energy efficiency and indoor air quality. That’s why, during the winter months, I include free thermal imaging with every service — to help homeowners spot and resolve these issues early.
Education, Transparency & Future Plans
Education & Transparency
I write all articles on the Eco Vent Blog, sharing guidance about ventilation, IAQ and moisture control. Every post is checked for accuracy and updated when standards change. For full transparency, see our Editorial & Corrections Policy
My Professional Plans for the Future
I am preparing to advance my qualifications with the goal of designing and commissioning industrial‑scale ventilation systems. Expanding into this field will allow me to apply my precision‑driven approach to more complex and large‑scale environments, while continuing to build on the foundation created with residential systems.
Plans for Eco Vent Ireland
Eco Vent will continue to grow as an educational resource for Irish homeowners. I plan to:
– publish more in‑depth articles and technical guides
– expand the Case Studies section with real examples from site visits,
– create tutorials for homeowners and DIY enthusiasts who want to understand or manage their own systems, and
– introduce EcoBot — an AI‑powered assistant designed to help visitors diagnose common ventilation issues. Many ventilation problems arise simply because homeowners were never shown how their system works or how to maintain it. EcoBot will serve as a first line of support, helping people get reliable guidance quickly and easily.
