AHU cleaning in Harcourt Hill, done properly
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you have fan sections that haven’t been cleaned in years and units that have only ever had filter changes, we can put it right.
In a village or hamlet like Harcourt Hill, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Harcourt Hill questions
Do you do school ventilation cleaning in Harcourt Hill in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Harcourt Hill. You can call us on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you work in villages like Harcourt Hill?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Do you work evenings or weekends?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
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 quote for both.
Managing agents and facilities teams in Harcourt Hill
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. Where responsibility is shared, records matter even more.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
To speed up the quote, please include:
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Harcourt Hill, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Clear loose items from the work area

Why it’s worth doing now in Harcourt Hill
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Rural sites cannot always move to another kitchen or room when something fails.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
