MVHR Installation
About This Service
MVHR Installation Done Right
Fresh, filtered air throughout your home, recovered heat you’d otherwise lose and lower energy waste — that’s the outcome of a correctly installed MVHR. AB Plumbing & Maintenance fit Axia MVHR units, mount equipment in lofts or cupboards and run rigid ducting to habitable rooms while extracting from kitchens and bathrooms. We balance supply and extract diffusers, commission the polymer heat exchanger to meet Building Regulations and leave a clear handover with straightforward maintenance advice.
Why Choose us for MVHR Installation?
Continuous supply of filtered fresh air removes cooking and bathroom moisture at source — reducing condensation, mould and odours without opening windows.
A correctly commissioned polymer heat exchanger recovers the bulk of warm air heat; the system is balanced to minimise heat loss and meet Building Regulations.
Tottington-based family firm with 32 years’ experience, Gas Safe registration and Axia MVHR accreditation — tidy installations, clear paperwork and aftercare you can rely on.
How It Works
Site survey & design
We measure rooms, inspect loft/cupboard space and map duct routes; you get a written proposal that explains where units, ducts and terminals will sit.
Supply & installation
Axia MVHR unit installed in the loft or a service cupboard, rigid ducting run to rooms, and filters fitted — all work carried out by our Axia-trained, Gas Safe-registered engineer.
Balancing & handover
We balance supply and extract diffusers, commission the heat exchanger, set humidity/boost controls, issue commissioning notes and give practical maintenance guidance.
Frequently Asked Questions
Find answers to common questions about our services and process.
Yes. MVHR can be retrofitted in many existing homes, though duct routing and unit location must be surveyed first. We assess loft space, service cupboards and room layouts during a site visit and advise on minimal-intrusion routes and whether rigid or semi-rigid ducting is best for your property.
When installed and balanced correctly, modern Axia units run quietly — the noise is usually only audible near the unit or grilles during high boost settings. Our commissioning process includes setting fan speeds and choosing terminal locations to keep noise well below typical living-room thresholds.
Routine maintenance is straightforward: filter checks and changes (typically every few months to a year depending on the filter class and household), periodic duct and heat exchanger inspections, and occasional cleaning of terminals. We provide a clear maintenance sheet and can arrange scheduled servicing if required.
MVHR recovers heat from extracted air so it reduces heat loss through ventilation, which can lower heating demand. It works alongside your heating system rather than replacing it; we can advise on how MVHR interacts with your existing boiler or central heating during the survey.
Yes. We design and commission systems to comply with current Building Regulations for ventilation. Every installation includes commissioning notes and records showing balanced airflow, correct extractor rates and compliance checks carried out by our Axia-trained, Gas Safe-registered engineer.
