AHU cleaning in New Forest, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. We are often asked to deal with dust built up on fan impellers and intake sections clogged with outdoor debris, on supply and extract fans, heating and cooling coils and internal panels.
For a building in or near New Forest, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Signs you need AHU cleaning in New Forest
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch when they notice one of these:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Coils clogged with dust and debris
- Odours coming through the supply air
Around New Forest, as anywhere, ventilation cleaning begins with an inspection.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Proof of accreditation you can verify
- Whether the price is fixed
- How VAT is shown on the quote
What AHU cleaning can’t fix
AHU cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly before booking.
Where we work
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Internal panels
- Heating and cooling coils
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Store the TR19 paperwork where auditors can find it
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
New Forest questions
Do you cover New Forest for AHU cleaning?
Yes. Our area runs across London and the South East, New Forest included. Get in touch with the details and we’ll arrange a survey.
Do you work at weekends in New Forest?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
How long will the unit be out of action?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, out of hours if needed.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Managing agents and facilities teams in New Forest
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Leave it or put it right?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s simpler to plan the work at New Forest now than to arrange it in a hurry later.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

The process
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near New Forest, let us know and we’ll plan around it.
- We agree a shutdown window that suits the building.
- We take before pictures 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 photos are taken and the certificate issued.
How to prepare
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down

What affects the quote in New Forest

- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- Working hours and out-of-hours timing
- The scale of the work
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
