About our AHU cleaning in Greenstead Green
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Common call-outs are for dust built up on fan impellers and intake sections clogged with outdoor debris, on supply and extract fans, drain trays and heating and cooling coils.
Work in a small place like Greenstead Green starts with agreeing access and timings.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What staff can safely do
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, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
What affects the cost of AHU cleaning
You’ll get a fixed price before work begins. It takes into account:
- Parking and loading at the site
- What state the system is in
- The times the site is available
- Whether several sites go on one quote
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Your opening hours and when the area is out of use
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Greenstead Green are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
Questions from Greenstead Green
Can you clean school ventilation in Greenstead Green during the holidays?
Yes, out-of-term visits are normal for schools. Around Greenstead Green, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Can you work in Greenstead Green outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Greenstead Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
When to call us in Greenstead Green
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Common reasons sites call us include:
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Rooms that smell stuffy when the system runs
If you run a surgery, dental practice or care home near Greenstead Green, clean ventilation matters as much to you as to a hospital like Halstead Hospital (about 1.8 miles north).
What to look for in a quote
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
- How VAT is shown on the quote
- What records you’ll receive afterwards
When something else is needed
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Controls and BMS settings that run the unit
- A system that’s undersized for the building
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
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.
Different parts, different methods
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.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
