About our AHU cleaning in Chelmsford
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. If you have filters that are clogged or overdue and intake sections clogged with outdoor debris, we can help.
Work in occupied buildings in Chelmsford is planned around the people using them, so we work zone by zone, out of hours where necessary.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. A big building in Chelmsford does not have to shut: the work can be spread across a few evenings or weekends.
- 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.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive

How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711 or email us and tell us about the site and its opening hours.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
How long will the unit be out of action?
The work takes from a few hours for a compact unit to a day or more for a large one. Large plant can be split over several shifts, so phone us on 0345 646 2711 or drop us a line to talk it through.
Are you insured?
Yes. We carry full insurance, and we have been trading since 2009.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Managing agents and facilities teams in Chelmsford
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
How the job changes from site to site
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Fixed quotes for AHU cleaning in Chelmsford
Your quote is based on your site. We consider:
- Travel, parking and unloading
- The number of sites or systems
- How big the system is
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
When you call or email, it’s useful to have:
- Wide pictures of the system and the area around it
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
When something else is needed
Some problems need a different service or another trade:
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
Parts of the system we cover
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Internal panels
- Filter sections
- Supply and extract fans
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Do not store bins or materials near the intake
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Ventilation in Chelmsford buildings
Food Standards Agency data includes about 33 schools, colleges and universities, about 36 care, childcare and hospital premises and about 4 hotels, B&Bs and guest houses across Chelmsford and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 30 miles out from central London, Chelmsford is part of the South East area we work across. The visit is fixed around your opening hours, not ours.

Classrooms and halls at schools such as Trinity Road Primary School are easiest to work in when pupils are away. Healthcare buildings such as Priory Hospital, about within half a mile north, depend on their ventilation; if you manage a surgery, clinic or care home near Chelmsford, yours matters too.

Common problems we fix in Chelmsford
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Common reasons sites call us include:
- Dirty coils holding back the airflow
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
Workplaces around Chelmsford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
