AHU cleaning in Herstmonceux
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, with the unit switched off and made safe first. The work covers heating and cooling coils, internal panels and supply and extract fans, and the jobs we see most are units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays.
In a village or hamlet like Herstmonceux, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Herstmonceux.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos 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.
Before we arrive
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
What a clean won’t put right
It’s worth knowing the limits before booking:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

AHU cleaning in Herstmonceux: local notes
Amberstone Hospital is the nearest hospital, about 2 miles west of Herstmonceux. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. About 46 miles out from central London, Herstmonceux is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
Healthcare ventilation, from large hospitals like Amberstone Hospital (about 2 miles west) to small clinics, depends on clean filters, coils and ducts. For schools like Herstmonceux Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Herstmonceux simpler. Systems in rural buildings are often out of sight and out of mind.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
How long does it take to clean an air handling unit?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, and you can call 0345 646 2711 or use the quote form to plan it.

Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
