Bosham Hoe AHU cleaning
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for commercial sites in Bosham Hoe and across West Sussex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
- Fan sections that haven’t been cleaned in years
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
AHU cleaning for kitchens and businesses in Bosham Hoe
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you are dealing with drain trays holding standing water and units that have only ever had filter changes, we can help.
In a village or hamlet like Bosham Hoe, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system help us make the most of a visit to a place like Bosham Hoe.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Photos are the quickest way to a quote: 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 we can price many jobs without a visit.
Advice
Do you need AHU cleaning in Bosham Hoe?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Look out for any of the following:
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
Ventilation work in and around Bosham Hoe is risk-based: inspect, then clean what needs it.
What your quote should include
- What’s included in the scope, part by part
- If the quote is a fixed price or an estimate
- Whether the quote is based on a survey or pictures
- How areas they cannot reach will be recorded
What happens if it’s left?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A planned visit to Bosham Hoe is easier to arrange than an emergency callout.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll explain what it covers.

Honest limits
AHU cleaning can’t fix everything, and we will tell you before work begins. It does not solve:
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
- Problems with the unit’s controls or sensors

FAQs for Bosham Hoe
Will you come out to Bosham Hoe?
Yes, we work in villages as well as towns, and Bosham Hoe is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Bosham Hoe for AHU cleaning?
Yes, Bosham Hoe is covered. To start, call us on 0345 646 2711 or send us an email with a few pictures of the system.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
How long does it take to clean an air handling unit?
Expect it to take from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
- Diary the inspection date recommended in the report
- Make sure condensate is draining away
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.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
