AHU cleaning in Wantage, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you’re dealing with filters that are clogged or overdue and air handling units never cleaned inside, we can put it right.
Buildings in towns like Wantage often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When your team notices a problem 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 can diagnose it and quote.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
How it works
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. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. A closed day, an evening or an early start: whichever suits your site in Wantage, we will book around it.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Wantage: your questions answered
Can a school’s ventilation in Wantage be done out of term time?
Yes, out-of-term visits are normal for schools. With about 8 schools and colleges on the FSA’s register within roughly a mile and a half of Wantage, it pays to plan holiday dates ahead. Just ring 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you work at weekends in Wantage?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Wantage needn’t be disturbed. Your opening times are the first thing we ask for.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you have insurance?
Yes. We carry full insurance, and we have been trading since 2009.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Which accreditations do you hold?
Duct Doctor is 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 the job changes from site to site
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so you can decide on any repairs.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Wantage buildings and their air
The FSA’s food hygiene register lists about 8 schools, colleges and universities and about 10 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in Wantage and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 57 miles out from central London, Wantage is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
School buildings such as St Mary's School are normally done in the holidays, so classrooms aren’t disturbed.

Honest limits
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It won’t put right:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design

Fixed quotes for AHU cleaning in Wantage
The survey tells us what the work involves. We look at:
- What state the system is in
- How big the system is
- The times the site is available
- One-off work versus a regular cycle
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- The site address and the type of premises
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Common problems we fix in Wantage
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
These are the problems we see most often:
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Dust built up on fan impellers
Around Wantage, as anywhere, ventilation cleaning begins with an inspection.
