AHU cleaning in New Copse
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. The work covers heating and cooling coils, drain trays and filter sections, and people most often call us about dirty coils holding back the airflow and drain trays holding standing water.
Work in a small place like New Copse starts with agreeing access and timings.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in New Copse before we set off.
- 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 pictures are taken and the certificate issued.
How to prepare
- Agree a time when the area can be out of use
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids

New Copse questions
Do you work overnight in New Copse?
Yes, nights and weekends are routine for us. The work in New Copse can fit around your hours. Your opening times are the first thing we ask for.
Is AHU cleaning available in New Copse?
Yes, New Copse is within the area we cover across London and the South East. Get in touch with the details and we will arrange a survey.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, with new panels fitted where needed.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
When to call us in New Copse
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
Alton Community Hospital, about 3.2 miles east, is the nearest hospital to New Copse, and healthcare sites of every size need their supply air kept clean.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Whether several sites go on one quote
- What state the system is in
- The size of the system
- Whether we need access equipment or extra panels
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
To help us quote quickly, send us:
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or email us.
What AHU cleaning cannot fix
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Building management system faults
- Airflow problems caused by the system’s design
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Heating and cooling coils
- Drain trays
- Internal panels
- Filter sections
- Dampers and louvres
- Supply and extract fans
Leave it or put it right?
Stuffy rooms and stale smells in a building in New Copse can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s worth booking a check, because nobody sees inside a duct day to day.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
