At ARMEEC LTD, we offer expert ventilation flow-rate balancing services across London, Manchester, and the wider UK to ensure your property’s ventilation system works efficiently. Whether you’re a homeowner, builder, or developer, we make sure your ventilation delivers the precise amount of fresh air to every room.
Ventilation balancing is the critical process of measuring and adjusting the airflow in a mechanical ventilation system. It’s a vital step when installing systems like Mechanical Extract Ventilation (MEV) or Mechanical Ventilation with Heat Recovery (MVHR). Without proper balancing, rooms can become stuffy, noisy, or damp, leading to poor air quality and unhappy occupants.
An unbalanced system is loud, inefficient, and non-compliant. Getting it commissioned properly protects your building and its occupants.
Guarantees that every single room gets the exact, correct amount of fresh supply air and extracted stale air based on design calculations.
Helps your MVHR or MEV system work efficiently and quietly. Over-extracting wastes heat, while under-extracting leaves moisture behind.
Actively prevents condensation, mould, and dampness caused by poor airflow, protecting the structural fabric of your property.
Legally meets Part F of the Building Regulations for ventilation standards, ensuring your project avoids costly compliance failures.
Increases occupant comfort and dramatically improves indoor air quality (IAQ) by flushing out VOCs, CO2, and airborne allergens.
A formal commissioning report is explicitly required for building control sign-off on all new builds and major renovations.
We take the guesswork out of ventilation commissioning, providing a seamless service from testing to final certification.
We accurately test the airflow from every supply and extract grille using strictly calibrated anemometer equipment.
We physically adjust the fan speeds at the main unit and tune the individual room dampers to precisely meet design targets.
We work collaboratively with your installers to resolve issues and fine-tune the system if immediate problems are identified on site.
We provide a comprehensive commissioning report showing final flow rates and full compliance with Part F regulations.
As homes across London and the UK are built with tighter envelopes to retain heat, mechanical ventilation has become critical. Without it, properties suffocate. Balancing your MEV or MVHR system ensures your property breathes correctly while maintaining the thermal efficiency required by the latest Building Regulations.
There are two primary types of mechanical systems we commission across the UK, each requiring specific testing methodologies:
MEV systems continuously extract stale, moisture-laden air from "wet rooms" (kitchens, bathrooms, utilities). We measure the extract rates at the terminals to ensure they meet the minimum whole-dwelling ventilation rates, relying on trickle vents in windows to supply fresh replacement air.
MVHR is more complex. It extracts stale air but uses its heat to warm incoming fresh air, which is then supplied to "habitable rooms" (bedrooms, living rooms). We must balance both the extract and supply legs simultaneously so the property doesn't become positively or negatively pressurized.
Failing to commission your ventilation system isn't just a paperwork issue. An unbalanced MVHR unit can operate at a fraction of its intended efficiency. This means you are paying to run a system that is actively leaking your home's heat, completely defeating the purpose of installing a heat recovery unit in the first place.
We provide fast booking and friendly advice throughout the entire commissioning process.
