About our AHU cleaning in Sacombe Green
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with coils clogged with dust and debris and filters that are clogged or overdue, we can put it right, from heating and cooling coils, dampers and louvres and drain trays onwards.
In a village or hamlet like Sacombe Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Good records are part of the job. Each visit is written up with photos, 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 ready for an insurer, fire officer or EHO.

What affects the cost of AHU cleaning
Sites vary more than people expect. What affects the quote:
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
- The size of the system
- How many systems or sites are involved
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
What to send for a quote
To help us quote quickly, please include:
- Your opening hours and when the area is out of use
- Any previous report or certificate
- Wide photos of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels

Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Planning a trip to Sacombe Green ahead is easier for everyone than a rushed one.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Why book with us
- A fixed price before any work starts
- One number for every site across the South East and London
- In business since 2009
- Fully insured

Do you need AHU cleaning in Sacombe Green?
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us after spotting one of these:
- Air handling units due a clean after building work
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Coils clogged with dust and debris
Healthcare ventilation, from large hospitals like Hertford County Hospital (about 4.7 miles south) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- Proof of insurance
- Proof of accreditation you can verify
- Whether the figure could change on the day
- Whether the quote shows VAT
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Sacombe Green, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call us on 0345 646 2711 or use the quote form.

Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
- Check the drain tray is emptying during routine visits
- Keep the area around the fresh air intake clear
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Honest limits
Some problems need a different service or another trade:
- A system that is undersized for the building
- Dirty ducts beyond the unit itself
- Building management system faults
