  • Inspection of the MVHR unit and its visible connections
  • Cleaning of the accessible unit interior
  • Cleaning of the accessible heat exchanger
  • Inspection and cleaning of accessible fan surfaces where the unit permits it
  • Replacement of the standard filter set where we have confirmed it in advance
  • Cleaning of accessible room terminals
  • Inspection of the condensate connection and drainage
  • Control, boost and bypass checks where these apply
  • Measured airflow checks at accessible terminals using calibrated equipment
  • Minor balancing adjustments where they are technically possible
  • Before and after photographs for your report
  • A written service report with our recommendations

Quoted separately

  • Full duct cleaning
  • Specialist, premium and unusual filters
  • Standard filters where the make and model were not supplied before attendance
  • Repairs
  • Replacement parts
  • Access equipment
  • Extensive fault investigation
  • Major rebalancing
  • Remedial work
  • Formal commissioning and airflow certification
  • Additional units beyond the one we have quoted
  • Return visits
  • Travel outside the regional coverage we confirm with you

What a standard visit involves

  • Inspect. The unit, its visible connections, the filters, the fan surfaces and the condensate connection, as far as they can be reached.
  • Clean. The accessible unit interior, the heat exchanger and the accessible room terminals. This is not a full duct clean.
  • Measure. Airflow at the accessible terminals using calibrated equipment, plus control, boost and bypass checks where these apply.
  • Report. A written record of what we found, the readings we took and what we recommend, with anything further quoted separately.

Three things to be clear about

  • Cleaning immediately behind an accessible room terminal is not a full duct clean. Full duct cleaning is separate work.
  • A service is planned maintenance. It is not a repair, and we do not promise that servicing will correct a fault your system already has.
  • Where we find work outside the standard service, we explain what we found, show you the evidence and quote separately before any chargeable work goes ahead.

Apartment and group servicing

From £140 including VAT per unit

That rate applies where three or more units at the same building are serviced during one coordinated attendance. One coordinated attendance means one planned visit to the building, with access to each unit arranged for that day.

It is a starting rate for the building. We confirm it once we know the unit types, how many units there are and how access will work. We already support apartment customers in Greater Manchester, alongside our regional work in the North East and the North.

  • Landlords with several units in one building
  • Managing agents and block managers
  • Residents arranging a shared visit with neighbours
  • Housing providers with ventilation across a scheme
  • Developers handing over a completed building

Repairs and replacements are assessed before they are quoted. We look at the unit, the fault, the parts position and the access, then set out the options and what each one costs. We do not publish repair, replacement or commissioning prices, because they depend on the unit, the fault and the property.

  • Fault finding on units that have stopped, are showing a warning or are underperforming
  • Fan, sensor and control faults
  • Duct, terminal and connection problems
  • Units where a part is no longer available from the manufacturer
  • Replacement of a unit that is past economic repair
  • Design and installation for new build, renovation and retrofit
  • Whole dwelling systems, and decentralised or extract systems for individual rooms
  • Positioning, commissioning and balancing on new installations

Commissioning is not the same as servicing

  • Commissioning sets a system up and verifies that it delivers its designed airflows. It is separate work and it is quoted separately.
  • A routine service includes measured airflow checks and minor balancing where that is technically possible. It does not set out to commission a system, and it does not by itself demonstrate compliance under Part F.

Nuaire MRXBOX servicing and official manuals

WWR services Nuaire MRXBOX units, subject to model, condition and access confirmation. Specifications below are summarised from Nuaire’s current product pages. Official documents open on Nuaire’s website.

What every model in this range shares, according to Nuaire

  • The heat exchanger is up to 95 per cent efficient, which Nuaire link to low specific fan power and a high SAP score.
  • The unit can be mounted on a wall or in a cupboard.
  • Filters are accessible from the front cover and no tools are required.
  • An opposite handed configuration is available.
  • An automatic bypass is fitted.
  • An optional Summer and Winter switch gives the occupant direct control of the heat exchanger bypass.
  • The unit comes with a two year warranty including parts and labour.

Signs a system needs attention

Tell us what you have noticed. These are the things owners most often describe, and what each one can point to.

A warning light on the unit
Different units use lights differently, so the first thing we need is the make and model. Send us a photograph of the unit and the light, and we will tell you what we think it means and what it usually takes to resolve.
The unit has become noisy
New noise usually means something has changed. Loaded filters, a build up on a fan, a loose panel, a worn bearing or a duct problem can all show up as noise. Some of that is addressed within a service and some needs a repair, which we assess and quote before any work goes ahead.
Weak airflow or no airflow at the terminals
Loaded filters and dirty terminals are common causes, and both are addressed within a standard service. Airflow can also be weak because of a duct problem, a control setting or a failing fan. Measured readings help us narrow down the cause and decide whether the system needs servicing, investigation, corrective work or recommissioning.
Condensation or lingering moisture
A system that is not moving the air it was designed to move can show up as moisture staying in the property longer than it should. We measure what the system is delivering rather than assume, then explain what we found and what would change it.
Odours moving between rooms
This can point to terminals and ductwork that need attention, to a system that is out of balance, or to how the system was set up. We inspect and measure, then explain what we found.
The unit seems stuck in boost
Boost is often triggered by a bathroom or kitchen switch, by a sensor or by a control setting. We check the controls, the boost trigger and the sensors where these apply.
Water around or below the unit
Do not touch the unit, its wiring or any switch near it, and do not try to mop up water around electrical equipment. If you think there is an immediate electrical danger, contact a qualified electrician straight away. Otherwise send us the make and model and describe what you can see, and photograph it only if you can do that without reaching near the unit.
The unit runs constantly or seems to cost more to run
A system working against loaded filters or restricted ductwork has to work harder. We can tell you what the system is delivering now. We do not promise a specific saving, because that depends on your property, your system and how it is used.

Systems we are asked about

Before we confirm a price we review the make, model, age, condition, parts availability and access for your system. That review is how we decide whether we can help, and it is why we ask for the details up front.

We do not publish a claim that we service every make and model, and we will tell you plainly if your system is one we cannot support. We also do not describe ourselves as approved, authorised or a partner of any manufacturer unless we hold the evidence for that exact wording.

How an enquiry works

STEP 1

You tell us about the system

Postcode, property type, unit make and model, roughly how many room terminals there are, how the unit can be reached, and anything you have noticed. Choose the closest option in the enquiry form and put the rest in the message, because the form has one message field rather than a field for each detail.

STEP 2

We confirm the price

We check whether the standard service suits your system and whether we can confirm the correct standard filter set, then give you the price for your own system and any travel position. Nothing is arranged until you have it.

STEP 3

We attend, then you get the evidence

We carry out the service, measure airflow at the accessible terminals, and send you a written report with your results, what we found and what we recommend. Anything beyond the standard service is quoted separately.

Frequently asked questions

Why is it a starting price rather than a fixed price?
Because properties differ. The unit type, the number of room terminals, how the unit is reached and where the property is all affect the visit. We confirm your price before we attend, so you are never asked to accept a figure you have not seen.
Are replacement filters included?
Standard filters are included where you told us the make and model before we attend and we confirmed the correct standard filter set. Specialist, premium and unusual filters are quoted separately, and so are standard filters where we could not confirm the set in advance.
How often should an MVHR system be serviced?
A professional service once a year suits most domestic systems. Filters usually need attention more often, and how often depends on the manufacturer’s instructions for your unit, the filter type, the environment around the property, how the system is used and the condition we find.
Will a service fix a fault?
Not necessarily, and we will not promise that it will. Servicing corrects some things, such as airflow lost to loaded filters and dirty terminals. A genuine fault is assessed and quoted as a repair.
Do you issue a Part F certificate?
Not as part of a routine service. Routine servicing does not demonstrate compliance under Part F. Commissioning and airflow certification are separate work, quoted separately, and we will tell you exactly what you would receive before you commit to it.
Can you service my make of unit?
We review the make, model, age, condition, parts availability and access before we confirm anything. We do not claim to service every make, and we will tell you plainly if yours is one we cannot help with.
Can you balance my system during a service?
We make minor balancing adjustments where they are technically possible. We measure what the system is delivering. Where design or previous commissioning information is available, we compare the readings with it. Where it is not available, we explain the limitations and whether further investigation or commissioning is appropriate. Not every system can be balanced successfully within a routine visit.

Enquire about an MVHR service

Choose the closest service option, then put the postcode, the property type, the unit make and model, roughly how many room terminals there are, how the unit is reached and what you have noticed into the message. The form has one message field, so the detail matters. We will confirm what your system needs and what it costs before anything is arranged.

Choose the service that matches your enquiry before you send the form.
