FAQs for Downend
Can you do AHU cleaning in Downend?
Yes. We work across London and the South East, and Downend is part of that. A fixed quote typically follows within one working day of the survey details.
Can the work in Downend be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Downend keeps running as normal. Let us know the hours you’re closed and we will book within them.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Do you have insurance?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so call 0345 646 2711, or email photos to talk it through.
What does AHU cleaning cost?
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 work begins.
About our AHU cleaning in Downend
If the units serving a building in Downend have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for plant that has been serviced but not cleaned and drain trays holding standing water, on dampers and louvres, internal panels and heating and cooling coils.
Somewhere as small as Downend, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, and we are 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.

How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy every part is to reach
- Travel, parking and unloading
- The size of the system
- How many systems or sites are involved
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Helping us quote
What to send for a quote:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which 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 Downend.
- We agree a shutdown window that suits the building.
- We take before photos 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 photos and issue the certificate and report.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711 or drop us a line.
Advice
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What we’re called out for in Downend
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Downend, that’s air they breathe for hours at a time.
Clients typically contact us when they notice one of these:
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Condensate trays that won’t empty
Healthcare ventilation, from large hospitals like Whitecroft Hospital (about 2.7 miles south-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether they recommend a next date
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
- Whether inaccessible sections are listed on the report
Why act early in Downend
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Equipment tucked in a roof space or outbuilding near Downend rarely gets looked at unless someone books it.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
