AHU cleaning in Upper Heyford, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Typical jobs include fan sections that haven’t been cleaned in years and coils clogged with dust and debris, on heating and cooling coils, drain trays and supply and extract fans.
In a smaller place like Upper Heyford, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
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. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

Upper Heyford questions
Can the work in Upper Heyford be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Upper Heyford does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you cover smaller places like Upper Heyford?
Yes. Upper Heyford is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What AHU cleaning cannot fix
To be straight with you, some problems need a different fix:
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think.

- How easy every part is to reach
- The condition we find in the survey
- The number of sites or systems
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:

The symptoms we’re asked about most include:
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow

Comparing quotes

- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- How VAT is shown on the quote
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Do not store bins or materials near the intake
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Keep inspection doors on the unit in good order
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
