Essex · Air handling unit cleaning
Ingatestone AHU cleaning
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for commercial sites in Ingatestone and across Essex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Booking now means the visit to Ingatestone is planned around you, not forced by a breakdown.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Why book with us
- Out-of-hours work and a 24/7 emergency line
- One contact for all your sites in London and the South East
- Full insurance on every job
- CHAS, SafeContractor and ISO 9001
About our AHU cleaning in Ingatestone
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include dirty fans and fan housings and debris and leaves in the fresh air intake, on internal panels, dampers and louvres and supply and extract fans.
For a building near Ingatestone, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What we are called out for in Ingatestone
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Ingatestone, that is air they breathe for hours at a time.
Common reasons sites call us include:
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Intake sections clogged with outdoor debris
If you manage offices or shops near Ingatestone station, their ventilation can be inspected and cleaned out of hours.
What to look for in a quote
- What insurance they carry
- Whether the quote is based on a survey or pictures
- Whether the whole system is included, or only the parts that are easy to reach
- What records you will receive afterwards
The process
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Because the survey comes first, a visit to Ingatestone can usually be finished without a second trip.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Let us know about parking and loading

Common questions in Ingatestone
Can you get to a site in Ingatestone?
Yes. Villages and rural sites across the South East are part of our work, Ingatestone included. Photos of the system and directions to the site help us plan the visit.
Can you come to Ingatestone after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
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.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
How we price AHU cleaning
The diagnosis comes before the price. We look at:
- How big the system is
- Any permits to work or inductions
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
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 play a part.
What to send for a quote
What to send for a quote:
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
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, the quote is fixed before any work is booked.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Book the next check in line with the report
- File each AHU report in the maintenance log
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
