- Debris and leaves in the fresh air intake
- Dust built up on fan impellers
- Odours coming through the supply air
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
- Don’t store bins or materials near the intake
- Report musty smells from the vents right away
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How we handle AHU cleaning in Cross End
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have air handling units never cleaned inside and fan sections that haven’t been cleaned in years, we can put it right, from internal panels, dampers and louvres and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.

What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711, or email photos.

How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
AHU cleaning in Cross End: local notes
Cross End’s nearest hospital, Halstead Hospital, is about 3.3 miles south-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. At about 47 miles from central London, Cross End sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare ventilation, from large hospitals like Halstead Hospital (about 3.3 miles south-west) to small clinics, depends on clean filters, coils and ducts. An inspection comes first for any ventilation job around Cross End, so the cleaning matches what’s there.
Cross End is about 4 miles north-east of Halstead, in Essex.

Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. Out of sight is the usual reason a rural system goes too long without attention.
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 will go through it with you.
What you get with us
- We diagnose before we treat
- Fixed quotes, normally within one working day
- Accredited under CHAS and SafeContractor, with ISO 9001
- Photo reports with every job
What we do, step by step
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Cross End, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
