About our AHU cleaning in Nob's Crook
If the units serving a building in Nob's Crook have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you’re dealing with fan sections that haven’t been cleaned in years and dirty coils holding back the airflow, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Nob's Crook, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
How to get a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Nob's Crook buildings and their air
Food Standards Agency data includes about 5 caring premises (care homes, nurseries and hospitals) in and around Nob's Crook, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 4.2 miles south of Nob's Crook is Moorgreen Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare buildings such as Moorgreen Hospital, about 4.2 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Nob's Crook, yours matters too. Wherever a school like Colden Common Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Why it’s worth doing now in Nob's Crook
If people in a building in Nob's Crook complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly.
What the work covers
- Internal panels
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Filter sections
- Heating and cooling coils
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.

Questions from Nob's Crook
Can you come to Nob's Crook after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Is Nob's Crook within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Is a quote from photos possible?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll normally reply within one working day.
What the work involves, part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
