Advice
AHU cleaning in Molehill Green, done properly
If the units serving a building in Molehill Green have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers internal panels, dampers and louvres and drain trays, and the jobs we see most are coils clogged with dust and debris and intake sections clogged with outdoor debris.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
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.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Keeping the system healthy
After the visit, a few habits help the work last:
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Keep inspection doors on the unit in good order
- Note any water around the unit or leaks below it
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

What affects the quote in Molehill Green
We quote each job individually. These are the things that affect it:
- How easy every part is to reach
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
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. Leave those to us.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Do you need AHU cleaning in Molehill Green?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
If you manage offices or shops near Stansted Airport station, their ventilation can be inspected and cleaned out of hours.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
