AHU cleaning in Pitsea
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, dampers and louvres and heating and cooling coils, and people most often call us about debris and leaves in the fresh air intake and coils clogged with dust and debris.
For a school, surgery or office in Pitsea, cleaning is planned around opening hours: out of hours, at weekends or during the holidays.
Duct Doctor has been trading since 2009, and we’re 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.

Can you do AHU cleaning in Pitsea?
Yes, Pitsea is within the area we cover across London and the South East. To start, call 0345 646 2711 or drop us a line with a few photos of the system.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Which sectors do you work in?
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 long does it take to clean an air handling unit?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, out of hours if needed.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. Before the visit, a few photos of the system and how to reach it help us plan the work in Pitsea.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions

Advice
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Why act early in Pitsea
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. Booking now keeps it a routine visit to Pitsea rather than an urgent one.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

Different parts, different methods
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
What AHU cleaning looks like in Pitsea
The FSA’s food hygiene register lists about 14 schools, colleges and universities and about 21 hospitals, care homes and childcare premises with registered kitchens or food service across Pitsea and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Pitsea’s nearest hospital, Basildon University Hospital, is about 2.3 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. We cover Pitsea, about 26 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
Hospitals such as Basildon University Hospital (about 2.3 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Pitsea are no different. For schools like The Basildon Upper Academy, the holidays are the usual time to inspect and clean ventilation. Workplaces around Pitsea station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

What affects the quote in Pitsea
Some jobs are bigger than they look, and some smaller. What affects the quote:
- A single visit or a regular plan
- Site rules, permits and inductions
- How many systems or sites are involved
- The condition we find in the survey
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- Any previous report or certificate
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then ring 0345 646 2711, or email photos.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. 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. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
What a clean won’t put right
Before booking, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
