Air handling unit cleaning in Drayton, Hampshire
Professional AHU cleaning in and around Drayton, booked around your opening hours and finished with a written report and pictures.
- Dust-coated heating and cooling coils
- Units that have only ever had filter changes
- Odours coming through the supply air
Looking after it afterwards
To keep the system working properly between visits:
- Report musty smells from the vents right away
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
AHU cleaning in Drayton, done properly
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. The work covers drain trays, filter sections and dampers and louvres, and common reasons people get in touch are leaves and litter drawn into the unit and dirty coils holding back the airflow.
Somewhere as small as Drayton, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Your questions about AHU cleaning in Drayton
Do you cover Drayton for AHU cleaning?
Yes, Drayton is covered. Just ring 0345 646 2711, or send details by email with a few details of the site.
Will you come out to Drayton?
Yes, we work in villages as well as towns, and Drayton is covered. The journey is planned ahead, so a few details about the route help.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Is a quote from photos possible?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures are not enough, we will survey first.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a small place like Drayton, a system that fails can take a site out of use.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

What a clean will not put right
Some problems need a different service or another trade:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer

What affects the quote in Drayton
Before we fix a price, we need to know a few things. We check:
- How many systems or sites are involved
- Parking and loading at the site
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
When you call or email, these details help:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
What AHU cleaning looks like in Drayton
The nearest hospital to Drayton is Petersfield Community Hospital, about 4.7 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. We cover Drayton, about 54 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare ventilation, from large hospitals like Petersfield Community Hospital (about 4.7 miles east) to small clinics, depends on clean filters, coils and ducts.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Do you need AHU cleaning in Drayton?
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
It’s time to book a visit if you see:
- Dirty fans and fan housings
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
If you manage a school such as East Meon Church of England Controlled Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- What paperwork you get at the end
- Which accreditations they hold, and whether you can check them
- Whether they recommend a next date
- What hours they’ll be on site
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Drayton 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.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
