AHU Cleaning in Old Heath
Looking for AHU cleaning in Old Heath? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and pictures.
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Condensate trays that will not empty
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
How we handle AHU cleaning in Old Heath
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you’re dealing with air handling units never cleaned inside and filters that are clogged or overdue, we can put it right.
Smaller buildings around Old Heath often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. Even a site near Old Heath that’s only busy part of the week needs its system checked on a schedule.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

Managing agents and facilities teams in Old Heath
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare in Old Heath and across Essex. Work can be phased by floor, building or site around the people who use them.
AHU cleaning around Old Heath
There are about 8 schools, colleges and universities and about 18 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within 1.5 miles or so of the middle of Old Heath. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.9 miles north-west of Old Heath is Essex County Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Old Heath, about 51 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
If you manage a school such as Old Heath Community Primary School, ventilation cleaning is best booked for the holidays.

How we price AHU cleaning
A fixed price needs a few facts first. We look at:
- How easy every part is to reach
- One-off work versus a regular cycle
- Site rules, permits and inductions
- Where the site is and how we reach it
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Asking for a quote
When you contact us, it’s useful to have:
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- Photos showing the whole system and its surroundings
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 pictures, get a survey first. Either way, you get a fixed price before we start.
Old Heath: your questions answered
Can you get to a site in Old Heath?
Yes, we work in villages as well as towns, and Old Heath is covered. Photos of the system and directions to the site help us plan the visit.
Can you clean school ventilation in Old Heath during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Old Heath. Booking early in the term gives the best choice of holiday dates.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
Is a quote from photos possible?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If photos aren’t enough, we will survey first.
Do you have insurance?
Yes. We’re fully insured, and the details are available on request.
How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Old Heath, not ours.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
Get a fixed quote
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.

What we’re called out for in Old Heath
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Keep an eye out for these warning signs:
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
Healthcare ventilation, from large hospitals like Essex County Hospital (about 1.9 miles north-west) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- Whether a written report and photos are included
- Exactly which parts of the system are covered
- How areas they cannot reach will be recorded
- Whether they’re fully insured
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- File each AHU report in the maintenance log
- Report musty smells from the vents straight away
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
