AHU cleaning for kitchens and businesses in Broughton Crossing
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Common call-outs are for coils clogged with dust and debris and blocked condensate drains and slimy trays, on filter sections, supply and extract fans and dampers and louvres.
Somewhere as small as Broughton Crossing, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Why it’s worth doing now in Broughton Crossing
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A fault that closes a site in a village like Broughton Crossing affects everyone who depends on it.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why Broughton Crossing businesses choose us
- Accredited under CHAS and SafeContractor, with ISO 9001

Questions from Broughton Crossing
Do you clean school ventilation in Broughton Crossing in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 13 schools, colleges and universities with registered kitchens within about a mile and a half of Broughton Crossing. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we will fit the work in.
Do you work overnight in Broughton Crossing?
Yes, evening, overnight and weekend work is normal for us. It means the site in Broughton Crossing keeps running as normal. Tell us your opening hours when you ask for a quote.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
How long does an AHU clean take?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What else we do in Broughton Crossing
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- One-off work versus a regular cycle
- How many systems or sites are involved
- The times the site is available
- Parking and loading at the site
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or email photos.
When to call us in Broughton Crossing
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.
Keep an eye out for these warning signs:
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
Hospitals such as Tindal Centre (about 0.8 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Broughton Crossing are no different.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- Whether the price is fixed
- If they look at the system before pricing
- Whether the work can be done while the site is closed
How the visit works
A visit follows the same order every time: protect the area, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Broughton Crossing is set by you, and the travel is our side of the planning.
- We survey the unit from photos or on site and agree what’s included.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
Getting a quote
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
When it’s something else
We’d rather tell you now than book work that will not help, so here are the limits:
- A system that is undersized for the building
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.
Where we work
- Drain trays
- Internal panels
- Dampers and louvres
