AHU Cleaning in Rackham
Our technicians work in Rackham on air handling unit cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Dust-coated heating and cooling coils
- Odours coming through the supply air
- Dust built up on fan impellers
Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
AHU cleaning in Rackham, done properly
We clean air handling units for buildings in Rackham and across West Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and the jobs we see most are dirty fans and fan housings and coils clogged with dust and debris.
For a building in or near Rackham, access is agreed in advance and the visit is planned around the journey.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What AHU cleaning can’t fix
We will not sell you work that does not address the problem, so here are the limits:
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
- Damaged coils beyond cleaning
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Filter sections
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Internal panels
- Supply and extract fans
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. A planned visit to Rackham is easier to arrange than an emergency callout.
Whatever the type of site, the quote works 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 explain each part.

How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Rackham, let us know and we’ll plan around it.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms

Hospitals such as Arundel and District Hospital (about 4.8 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Rackham are no different. Ventilation work in and around Rackham is risk-based: inspect, then clean what needs it.

Your questions about AHU cleaning in Rackham
Can you come to Rackham after we close?
Yes, we can come after you close and finish before you open. The work in Rackham can fit around your hours. Tell us your opening hours when you ask for a quote.
Is Rackham within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Rackham included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
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.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How long will the unit be out of action?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, including evenings or weekends.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What affects the cost of AHU cleaning
Sites vary more than people expect. What affects the quote:
- One-off work versus a regular cycle
- Travel, parking and unloading
- Working hours and out-of-hours timing
- Any permits to work or inductions
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before work begins.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Your last certificate, test record or report
- The postcode and the type of business
- Any access panels or hatches you can see
- The times we could work without disrupting the site
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
