Brighton and Hove · Air handling unit cleaning
Air handling unit cleaning in Seven Dials, Brighton and Hove
AHU cleaning for Seven Dials, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
- Drain trays holding standing water
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
AHU cleaning in Seven Dials, 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. The work covers internal panels, heating and cooling coils and drain trays, and the jobs we see most are drain trays holding standing water and air handling units never cleaned inside.
For a building near Seven Dials, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the visit works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. For a place like Seven Dials, we load the van from the survey notes so the work can be done in one visit where possible.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Agree a time when the area can be out of use
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What affects the quote in Seven Dials
The diagnosis comes before the price. The main factors are:
- The condition we find in the survey
- A single visit or a regular plan
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- When the site is open and when it’s quiet
- The postcode and the type of business
- Any access panels or hatches you can see
- Problems your staff have spotted
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 questions in Seven Dials
Can ventilation in schools around Seven Dials be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 57 schools and colleges with food registrations within roughly a mile and a half of Seven Dials. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Seven Dials?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do you need to switch the unit off?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What the work involves, part by part
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Honest limits
It’s worth knowing the limits before booking:
