AHU cleaning in High Cross
Our AHU cleaning covers sites in High Cross and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with odours coming through the supply air and dirty coils holding back the airflow, we can put it right.
In a village or hamlet like High Cross, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How it works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like High Cross are booked in advance, at a time that suits whoever runs the site.
- 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.
- 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
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
Why it’s worth doing now in High Cross
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. A planned visit to High Cross is easier to arrange than an emergency callout.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

Managing agents and facilities teams in High Cross
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
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.
Common problems we fix in High Cross
Whatever surrounds a building in High Cross, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
What we’re most often called out for:
- Fan sections that haven’t been cleaned in years
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
Hospitals such as Petersfield Community Hospital (about 2.7 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near High Cross are no different.

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
AHU cleaning around High Cross
High Cross is about 50 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. For High Cross, the closest hospital is Petersfield Community Hospital, roughly 2.7 miles south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Froxfield Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Look at the condensate drain whenever the unit is serviced
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Report stiff or damaged access doors
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 confirm water is draining away.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Your questions about AHU cleaning in High Cross
Do you work overnight in High Cross?
Yes, nights and weekends are routine for us. It means the site in High Cross keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you work in villages like High Cross?
Yes, we work in villages as well as towns, and High Cross is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
