AHU cleaning in Hambrook
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you’re dealing with blocked condensate drains and slimy trays and rooms that smell stuffy when the system runs, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, 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.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Hambrook buildings and their air
There are about 4 schools, colleges and universities and about 6 hospitals, care homes and childcare premises on the FSA’s food hygiene register in Hambrook and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. At about 56 miles from central London, Hambrook sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. About 4.7 miles west of Hambrook is Havant War Memorial Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Chidham Parochial Primary School are easiest to work in when pupils are away. Healthcare buildings such as Havant War Memorial Hospital, about 4.7 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Hambrook, yours matters too.
Hambrook is about 5 miles west of Chichester, in West Sussex.

How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
What to send for a quote
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide photos of the system and the area around it
- The postcode and the type of business
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711 or drop us a line.

What else we do in Hambrook
Signs you need AHU cleaning in Hambrook
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
If you run an office near Nutbourne station, its supply ductwork can gather dust for years before anyone looks inside.
Before you book anyone
- What records you will receive afterwards
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If they look at the system before pricing
- What insurance they carry
Between visits
Results last longer with the right care. Here’s what we suggest:
- Check the drain tray is emptying during routine visits
- Keep inspection doors on the unit in good order
- Note any water around the unit or leaks below it
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Your questions about AHU cleaning in Hambrook
Can the work in Hambrook be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Hambrook needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Will you come out to Hambrook?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What AHU cleaning can’t fix
We will not sell you work that does not address the problem, so here are the limits:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Hambrook before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
How to get a quote
Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
