Signs you need AHU cleaning in Childerditch
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Look out for any of the following:
- Units that have only ever had filter changes
- Dirty filters cutting the airflow
- Drain trays holding standing water
- Dust-coated heating and cooling coils
Healthcare buildings such as Spire Hartswood Hospital, about 1.8 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Childerditch, yours matters too.
Questions to ask before booking
- Whether VAT is included
- Exactly which parts of the system are covered
- Whether the quote is based on a survey or pictures
- Whether the figure could change on the day
How we handle AHU cleaning in Childerditch
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, internal panels and heating and cooling coils, and people most often call us about dirty fans and fan housings and leaves and litter drawn into the unit.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Keeping the system healthy
After the visit, a few habits help the work last:
- Don’t ignore odours coming through the grilles
- Plan the next inspection before the last report gets filed away
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Childerditch and across Essex. Work can be phased by floor, building or site around the people who use them.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Childerditch, the journey is planned ahead and the visit arranged around the site’s hours.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.

- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet

Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.

Common questions in Childerditch
Do you cover smaller places like Childerditch?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you work at weekends in Childerditch?
Yes, evening, overnight and weekend work is normal for us. The work in Childerditch can fit around your hours. Your opening times are the first thing we ask for.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Are you insured?
Yes. We are fully insured, and the details are available on request.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply ring 0345 646 2711 or drop us a line.
Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Systems in rural buildings are often out of sight and out of mind.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
