In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
How we handle AHU cleaning in Crawley
We clean air handling units for buildings in Crawley and across Hampshire, 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. We’re often asked to deal with plant that has been serviced but not cleaned and units needing a clean before a new tenant or handover, on internal panels, supply and extract fans and heating and cooling coils.
Work in a small place like Crawley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
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.

Common questions in Crawley
Do you cover Crawley for AHU cleaning?
Yes. We work across London and the South East, and Crawley is part of that. You can call us on 0345 646 2711 or use the quote form and tell us what needs doing.
Can the work in Crawley be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Crawley keeps running as normal. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711 or email us.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, ring 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
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, especially where there’s been moisture. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.

What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Building management system faults
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think before booking.
What the work covers
- Internal panels
- Filter sections
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Drain trays
Signs you need AHU cleaning in Crawley
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Clients typically contact us when they notice one of these:
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Crawley, clean ventilation matters as much to you as to a hospital like Royal Hampshire County Hospital (about 4.5 miles south-east).
Questions to ask before you book
- How VAT is shown on the quote
- How areas they can’t reach will be recorded
- Whether they’re fully insured
- Proof of accreditation you can verify
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Crawley, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Advice
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Do not ignore odours coming through the grilles
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

Fans and fan sections
