AHU Cleaning in Highwood
Professional AHU cleaning in and around Highwood, timed so the site keeps working and finished with a written report and pictures.
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
Leave it or put it right?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Our emergency line runs 24/7, but a planned visit to Highwood is calmer for everyone.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Why us?
- Fixed quotes from a survey or pictures
- Work around your opening hours, with 24/7 emergency cover
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- CHAS and SafeContractor accredited, with ISO 9001

AHU cleaning for kitchens and businesses in Highwood
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you have fan sections that haven’t been cleaned in years and drain trays holding standing water, we can help, from heating and cooling coils, supply and extract fans and filter sections onwards.
For a building in or near Highwood, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

When to call us in Highwood
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
What we are most often called out for:
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Dirty filters cutting the airflow
Healthcare ventilation, from large hospitals like St Leonard's Hospital (about 5.5 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Before booking anyone
- Whether inaccessible sections are listed on the report
- Whether they’re fully insured
- Whether they recommend a next date
- Whether a written report and pictures are included
When something else is needed
We won’t sell you work that does not address the problem, so here are the limits:
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly before booking.
Where we work
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Internal panels
Highwood questions
Is Highwood within the area you cover?
Yes, Highwood is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you work in Highwood outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Highwood does not have to lose a day’s trading. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Highwood.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

How the job changes from site to site
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Don’t ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
