AHU cleaning in Bitterne Park, done properly
An air handling unit is the heart of a building’s ventilation: 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, so cleaning the unit matters as much as cleaning the ducts. We’re often asked to deal with plant that has been serviced but not cleaned and dust built up on fan impellers, on drain trays, dampers and louvres and internal panels.
For a building near Bitterne Park, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
What a clean won’t put right
It’s worth knowing the limits before booking:
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think before booking.
What the work covers
- Filter sections
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Drain trays
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. When a site near Bitterne Park shuts unexpectedly, the people who rely on it notice at once.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.

What affects the quote in Bitterne Park
There’s no set price list, because no two systems are the same. The quote depends on:
- The size of the system
- A single visit or a regular plan
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Wide pictures of the system and the area around it
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room

FAQs for Bitterne Park
Do you cover smaller places like Bitterne Park?
Yes. Villages and rural sites across the South East are part of our work, Bitterne Park included. Just mention lanes, gates or anything else about the site when you book.

What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we 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 are fully insured.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can you clean without disrupting the building?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. For a place like Bitterne Park, we load the van from the survey notes so the work can be done in one visit where possible.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Mention any sign-in, permit or induction we need

Advice
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 won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
