AHU cleaning in Waterside
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for dirty fans and fan housings and air handling units never cleaned inside, across heating and cooling coils, internal panels and drain trays.
For a building in or near Waterside, access is agreed in advance and the visit is planned around the journey.
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 carry full insurance.

What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.

What AHU cleaning looks like in Waterside
Going by the FSA’s register, there are about 20 schools, colleges and universities and about 18 hospitals, care homes and childcare premises serving food across Waterside and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Waterside, about 26 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. About 2.5 miles south of Waterside is Amersham Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Waterside Primary Academy are easiest to work in when pupils are away.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
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’re happy to quote for all of it.
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Waterside, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down

How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- How big the system is
- Access, including roofs, risers and ceiling voids
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.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Why act early in Waterside
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Waterside simpler. With notice, the visit to Waterside can be fitted around your bookings and events.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
