AHU cleaning for kitchens and businesses in Millbridge
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, heating and cooling coils and dampers and louvres, and the jobs we see most are rooms that smell stuffy when the system runs and dirty filters cutting the airflow.
Work in a small place like Millbridge starts with agreeing access and timings.
The sign-off is always in writing: a written report, dated and illustrated with pictures, 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.

Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Millbridge, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear the space around the work
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.

How we price AHU cleaning
You’ll get a fixed price before we start. It takes into account:
- The condition we find in the survey
- How easy every part is to reach
- Where the site is and how we reach it
- Working hours and out-of-hours timing
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
When you contact us, it’s useful to have:
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Watch for drips or damp patches near the plant
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Report stiff or damaged access doors
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Busy, occupied buildings like these are where clean supply air matters most. For Millbridge, the closest hospital is Chase Community Hospital, roughly 5.7 miles south-west.

When to call us in Millbridge
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Look out for these warning signs:

- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.

How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, typically ready within one working day.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do you need to switch the unit off?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
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.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
