Common problems we fix in Chalgrove
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Chalgrove, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
- Leaves and litter drawn into the unit
If you manage a school such as Chalgrove Community Primary School, ventilation cleaning is best booked for the holidays.

AHU cleaning in Chalgrove
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers filter sections, internal panels and drain trays, and the jobs we see most are rooms that smell stuffy when the system runs and air handling units never cleaned inside.
For a building near Chalgrove, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What AHU cleaning can’t fix
Some problems need a different service or another trade:
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
If in doubt, ring 0345 646 2711 or email us and we will say what we think before booking.
Where we work
- Drain trays
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Internal panels
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Your questions about AHU cleaning in Chalgrove
Is Chalgrove in your area for AHU cleaning?
Yes, we work in Chalgrove and the places around it. Just ring 0345 646 2711 or use the quote form with a few details of the site.
Do you cover smaller places like Chalgrove?
Yes. Chalgrove is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Can you quote from photos?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If pictures are not enough, we will survey first.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Between visits
So the system stays in good health:
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Change filters on schedule and log each change
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
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
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. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. In a place like Chalgrove, we fit the visit around your hours.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Booking now means the visit to Chalgrove is planned around you, not forced by a breakdown.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
