What AHU cleaning looks like in Perry Green
Food Standards Agency records list about 3 hospitals, care homes and childcare premises registered as food businesses across Perry Green and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Perry Green’s nearest hospital, William Julien Courtauld Hospital, is about 3.5 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. We cover Perry Green, about 40 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.
Healthcare buildings such as William Julien Courtauld Hospital, about 3.5 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Perry Green, yours matters too. If you manage a school such as Alec Hunter Academy, ventilation cleaning is best booked for the holidays.
Perry Green is about 3 miles south-east of Braintree, in Essex. Whether your site is in the middle of Perry Green or further out, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building.

How we handle AHU cleaning in Perry Green
Where a building in Perry Green has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers heating and cooling coils, supply and extract fans and filter sections, and the jobs we see most are coils clogged with dust and debris and fan sections that haven’t been cleaned in years.
In a village or hamlet like Perry Green, 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. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A planned visit to Perry Green is easier to arrange than an emergency callout.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

When it’s something else
Some problems need a different service or another trade:
- A system that’s undersized for the building
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover
- Dampers and louvres
- Drain trays
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Filter sections
Keeping the system healthy
Results last longer with the right care. We suggest:
- Stick to the filter change plan
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Fixed quotes for AHU cleaning in Perry Green
Every site gets its own quote. This is what makes a difference:
- How big the system is
- What state the system is in
- The times the site is available
- Any permits to work or inductions
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
We can often survey from pictures. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
For AHU cleaning in Perry Green, call us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote usually follows within one working day.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
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.
Questions from Perry Green
Do you cover smaller places like Perry Green?
Yes, we work in villages as well as towns, and Perry Green is covered. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Perry Green?
Yes, evening, overnight and weekend work is normal for us. It means the site in Perry Green keeps running as normal. Your opening times are the first thing we ask for.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Perry Green and turn up when the site is quiet.
- 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
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
Ask for a quote
The quickest way to a quote is to send pictures: 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.
