AHU cleaning in Bentworth
Heating and cooling coils trap dust that gets past the filters. 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’re dealing with units needing a clean before a new tenant or handover and debris and leaves in the fresh air intake, we can help, from filter sections, dampers and louvres and heating and cooling coils onwards.
For a building in or near Bentworth, access is agreed in advance and the visit is planned around the journey.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Questions from Bentworth
Do you cover smaller places like Bentworth?
Yes. Bentworth is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Can the work in Bentworth be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Bentworth keeps running as normal. Tell us your opening hours when you ask for a quote.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long does an AHU clean take?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
What else we do in Bentworth
How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Bentworth, lanes, gates and parking are worth mentioning in advance.
- 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.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool

Related advice
Different parts, different methods
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.

What we’re called out for in Bentworth
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Signs it’s time to call us include:
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
Healthcare buildings such as Alton Community Hospital, about 2.8 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Bentworth, yours matters too.
Before you book anyone
- How they set the interval to the next visit
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system can’t be accessed
- What’s included in the scope, part by part
Multi-site and managed buildings
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 can quote for the whole system.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
How we price AHU cleaning
We do not publish a price list, because sites vary so much. What we look at:
- The size of the system
- Whether several sites go on one quote
- One-off work versus a regular cycle
- Where the site is and how we reach it
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What to send for a quote
We can often survey from pictures. The most useful are:
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
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 so you know the cost before any work starts.
