How we handle AHU cleaning in Lancing
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with coils clogged with dust and debris and air handling units never cleaned inside, across supply and extract fans, drain trays and internal panels.
In a smaller place like Lancing, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common questions in Lancing
Is Lancing within the area you cover?
Yes, we work in villages as well as towns, and Lancing is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Can a school’s ventilation in Lancing be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Lancing. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711, or email photos.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the system
- The number of sites or systems
- One-off work versus a regular cycle
- The condition of the system
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
Asking for a quote
We can often survey from pictures. Try to include:
- Any previous report or certificate
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What AHU cleaning cannot fix
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.

Between visits
Think of this as the after-treatment advice, in brief:
- Report stiff or damaged access doors
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What we’re called out for in Lancing
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Signs it’s time to call us include:
- Dust built up on fan impellers
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
- Dust-coated heating and cooling coils
Workplaces around Lancing station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What your quote should include
- Exactly which parts of the system are covered
- What insurance they carry
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
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.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We plan the journey to Lancing and bring what the job is likely to need.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
Ask for a quote
Photos are enough for some jobs, while others need a look on site. 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 work begins.
Advice
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
