About our AHU cleaning in Hastingleigh
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for units that have only ever had filter changes and rooms that smell stuffy when the system runs, on supply and extract fans, drain trays and filter sections.
Somewhere as small as Hastingleigh, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the job changes from site to site
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.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A planned visit to Hastingleigh is easier to arrange than an emergency callout.
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 will have a fixed price before work begins.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We check:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- Site requirements such as sign-in and permits
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Asking for a quote
You do not need the technical terms. Just send:
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- When the site is open and when it’s quiet

Your questions about AHU cleaning in Hastingleigh
Do you work at weekends in Hastingleigh?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Hastingleigh needn’t be disturbed. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Will you come out to Hastingleigh?
Yes, Hastingleigh is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Is a quote from pictures possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What’s TR19?
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.
Ventilation in Hastingleigh buildings
Hastingleigh is about 52 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Hastingleigh’s nearest hospital, William Harvey Hospital, is about 3.9 miles south-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Hastingleigh, clean ventilation matters as much to you as to a hospital like William Harvey Hospital (about 3.9 miles south-west). For schools like Bodsham Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. Seeing the system in pictures first means the trip to Hastingleigh can be planned properly.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Between visits
So the system stays in good health:
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents straight away
- Don’t store bins or materials near the intake
- Keep filter changes on time and recorded
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.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
