About our AHU cleaning in Sandhills
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Typical jobs include drain trays holding standing water and units needing a clean before a new tenant or handover, on internal panels, filter sections and heating and cooling coils.
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.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Your questions about AHU cleaning in Sandhills
Do you work in villages like Sandhills?
Yes. Villages and rural sites across the South East are part of our work, Sandhills included. Let us know about access, parking and anything unusual about getting there when you book.
Can ventilation in schools around Sandhills be cleaned out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Sandhills. Just give us a ring on 0345 646 2711 or email us with your term dates and we will plan around them.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
What should I send you?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Sandhills, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or send us an email.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
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 is where we come in.
Multi-site and managed buildings
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How many systems or sites are involved
- The size of the system
- Any permits to work or inductions
- One-off work versus a regular cycle
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Helping us quote
We can often survey from pictures. The most useful are:
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711 or use the quote form.

How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
