AHU cleaning in Hoo, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We are often asked to deal with dirty filters cutting the airflow and drain trays holding standing water, on dampers and louvres, internal panels and drain trays.
Somewhere as small as Hoo, ducted ventilation is normally 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.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What staff can safely do
Day-to-day cleaning is something your team can do: 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, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
AHU cleaning around Hoo
The nearest hospital to Hoo is Queen Elizabeth the Queen Mother Hospital, about 5 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare buildings such as Queen Elizabeth the Queen Mother Hospital, about 5 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Hoo, yours matters too.

Questions from Hoo
Can you come to Hoo after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Hoo can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you get to a site in Hoo?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or email us and tell us about the site and its opening hours.
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- Site rules, permits and inductions
- One-off work versus a regular cycle
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Where the site is and what kind of site it is
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
- Don’t store bins or materials near the intake
- Change filters on schedule and log each change
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Hoo run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, call 0345 646 2711, or send details by email.
Advice
What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Why deal with it now?
If people in a building in Hoo complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Equipment tucked in a roof space or outbuilding near Hoo rarely gets looked at unless someone books it.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
