MVHR Commissioning

Get the most out of your MVHR system — with expert commissioning designed for comfort, efficiency, and peace of mind.

What is MVHR Commissioning?

MVHR (Mechanical Ventilation with Heat Recovery) commissioning is the final and most crucial step in getting your ventilation system working exactly as it should. It's where we fine-tune your setup to deliver optimal airflow, ensure full compliance with building regulations and give you the healthy, energy-efficient environment you’ve been planning for.

At 21 Degrees, we don’t just install your MVHR system — we make sure it performs perfectly from day one. Our commissioning service is precise, professional, and fully tailored to your home.

Very professional. They do what they say, when the say they will do it. They designed and certified our Mechanical Ventilation System which is extremely quiet, extremely well balanced and only uses 25 W to run. Extremely happy to work with them
