AHU cleaning in Earlswood
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you have intake sections clogged with outdoor debris and dust-coated heating and cooling coils, we can help, from internal panels, heating and cooling coils and dampers and louvres onwards.
Visits to a place like Earlswood are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
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.

Earlswood questions
Will you come out to Earlswood?
Yes. Earlswood is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can a school’s ventilation in Earlswood be done out of term time?
Yes. The holidays are the usual time for school work. Around Earlswood, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
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 will talk you through the next steps.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
Can you clean without disrupting the building?
Yes, wherever it helps the building. We plan the shutdown window with you.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. For a site near Earlswood, the work is booked around your opening hours, evenings and weekends included.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
Getting a 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.

What AHU cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Building management system faults
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.
Parts of the system we cover
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Internal panels
- Filter sections
- Dampers and louvres

What else we do in Earlswood
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
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.
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, so cleaning the ducts without the unit only goes so far. Around Earlswood, a kitchen or building out of action is missed straight away.
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 go through it with you.

Keeping the system healthy
Once we have finished, these simple steps help:
- Keep inspection doors on the unit in good order
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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.
