AHU Cleaning in Chilgrove

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
AHU cleaning in Chilgrove
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. We’re often asked to deal with drain trays holding standing water and odours coming through the supply air, on internal panels, heating and cooling coils and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Managing agents and facilities teams in Chilgrove
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
When it’s something else
In fairness, some problems need a different fix:
- Leaking heating or cooling coils
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.

What affects the quote in Chilgrove
Every site gets its own quote. This is what makes a difference:
- Any permits to work or inductions
- The times the site is available
- How many systems or sites are involved
- Where the site is and how we reach it
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
You do not need the technical terms. Just send:
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- The times we could work without disrupting the site
To get a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

How the visit works
We turn up 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 from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Chilgrove, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
- Clear the space around the work

Between visits
After the visit, a few habits help the work last:
- Keep filter changes on time and recorded
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
- Don’t store bins or materials near the intake
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Chilgrove questions
Can you do AHU cleaning in Chilgrove?
Yes. We work across London and the South East, and Chilgrove is part of that. You can give us a ring on 0345 646 2711 or send us an email and let us know what needs doing.
Do you work at weekends in Chilgrove?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Chilgrove needn’t be disturbed. Tell us your opening hours when you ask for a quote.
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 the last report help too. After that, simply phone us on 0345 646 2711 or use the quote form.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
How long does it take to clean an air handling unit?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
