AHU cleaning in Lee-on-the-Solent
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you’re dealing with debris and leaves in the fresh air intake and plant that needs cleaning after a refit, we can put it right.
Around a place like Lee-on-the-Solent, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Duct Doctor has been trading since 2009, and we are 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.

Questions from Lee-on-the-Solent
Do you do school ventilation cleaning in Lee-on-the-Solent in the summer holidays?
Yes, and it’s the easiest time to do it. Around Lee-on-the-Solent, the Food Standards Agency lists about 16 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we will fit the work in.
Will you come out to Lee-on-the-Solent?
Yes. Villages and rural sites across the South East are part of our work, Lee-on-the-Solent included. Let us know about access, parking and anything unusual about getting there when you book.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Is there a report after cleaning?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Can you quote from photos?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- A few general shots of the system
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. A planned visit to Lee-on-the-Solent fits your hours; an emergency does not.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes

What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a place like Lee-on-the-Solent are planned ahead, so we arrive with what the survey says the job needs.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Have your last certificate or report to hand

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Book the next check in line with the report
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
