Air handling unit cleaning in Charlton, West Sussex
AHU cleaning for Charlton, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Condensate trays that will not empty
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. If you can send photos, we can arrive in Charlton knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Arrange a key holder or contact on site
Getting a quote
Some systems can be priced from pictures; 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.
Advice
About our AHU cleaning in Charlton
Where a building in Charlton has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have debris and leaves in the fresh air intake and blocked condensate drains and slimy trays, we can help, from heating and cooling coils, drain trays and dampers and louvres onwards.
For a building in or near Charlton, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

FAQs for Charlton
Can the work in Charlton be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Charlton needn’t be disturbed. Your opening times are the first thing we ask for.
Will you come out to Charlton?
Yes, we work in villages as well as towns, and Charlton is covered. Just mention lanes, gates or anything else about the site when you book.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What do you do with what you remove?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
How much does AHU cleaning cost in Charlton?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
How we price AHU cleaning
A fixed price needs a few facts first. We check:
- One-off work versus a regular cycle
- Travel, parking and unloading
- Working hours and out-of-hours timing
- How easy every part is to reach
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or email us, and we’ll explain what it covers.
What we need to know
Before you ask for a quote, gather:
- The site address and the type of premises
- Any previous report or certificate
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
When it’s something else
We won’t sell you work that does not address the problem, so here are the limits:
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Internal panels
AHU cleaning around Charlton
Charlton’s nearest hospital, Chichester Centre, is about 4.6 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. At about 49 miles from central London, Charlton sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Chichester Centre, about 4.6 miles south, is the nearest hospital to Charlton, and healthcare sites of every size need their supply air kept clean. Wherever a school like Singleton CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.

What else we do in Charlton
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. With notice, the visit to Charlton can be fitted around your bookings and events.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
