How we handle AHU cleaning in Kingwood Common
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers filter sections, heating and cooling coils and drain trays, and common reasons people get in touch are dust-coated heating and cooling coils and plant that has been serviced but not cleaned.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has 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 are fully insured.

How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition of the system
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.
Helping us quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Kingwood Common and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
How the job changes from site to site
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Do you need AHU cleaning in Kingwood Common?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us include:
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
Battle Hospital, about 5.1 miles south, is the nearest hospital to Kingwood Common, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- Whether VAT is included
- How areas they cannot reach will be recorded
- When they can work, and whether that is outside your opening hours
- If they look at the system before pricing
Kingwood Common questions
Can you work in Kingwood Common outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Kingwood Common needn’t be disturbed. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Do you offer AHU cleaning in Kingwood Common?
Yes. We work across London and the South East, and Kingwood Common is part of that. You can give us a ring on 0345 646 2711 or email us and tell us what needs doing.
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.
How much does AHU cleaning cost in Kingwood Common?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
- Look at the condensate drain whenever the unit is serviced
- Clear leaves and litter away from the intake
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.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Seeing the system in photos first means the trip to Kingwood Common can be planned properly.
- 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.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
