About our AHU cleaning in Ashurst Bridge
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 dampers and louvres, internal panels and drain trays, and the jobs we see most are air handling units due a clean after building work and blocked condensate drains and slimy trays.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Ashurst Bridge.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Agree a time when the area can be out of use
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Do you need AHU cleaning in Ashurst Bridge?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Ashurst Hospital (about 1.4 miles south) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- If they look at the system before pricing
- What paperwork you get at the end
- What’s included in the scope, part by part
- What insurance they carry
Ashurst Bridge buildings and their air
There are about 16 schools, colleges and universities and about 27 hospitals, care homes and childcare premises on the FSA’s food hygiene register in and around Ashurst Bridge, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.4 miles south of Ashurst Bridge is Ashurst Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like Hazel Wood Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- Parking and loading at the site
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- The postcode and the type of business
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
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, you get a fixed price before we start.
Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s worth booking a check, because nobody sees inside a duct day to day.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
- Keep inspection doors on the unit in good order
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Different parts, different methods
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
