Knights Enham questions
Will you come out to Knights Enham?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Can the work in Knights Enham be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Knights Enham needn’t be disturbed. Tell us your opening hours when you ask for a quote.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How much does AHU cleaning cost in Knights Enham?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
AHU cleaning for kitchens and businesses in Knights Enham
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers filter sections, drain trays and heating and cooling coils, and common reasons people get in touch are air handling units never cleaned inside and plant that needs cleaning after a refit.
Somewhere as small as Knights Enham, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site around the people who use them.
Do you need AHU cleaning in Knights Enham?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Clients usually contact us after spotting one of these:
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
For schools like Roman Way Primary School, the holidays are the usual time to inspect and clean ventilation.

What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Seeing the system in photos first means the trip to Knights Enham can be planned properly.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids

Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
- Keep inspection doors on the unit in good order
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.
Where we work
- Internal panels
- Supply and extract fans

What else we do in Knights Enham
What happens if it’s left?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Rural sites can’t always move to another kitchen or room when something fails.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
