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.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
AHU cleaning for kitchens and businesses in Petersfield
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with plant that has been serviced but not cleaned and air handling units with blocked filters, we can help, from filter sections, internal panels and drain trays onwards.
In Petersfield, ventilation in schools and offices is cleaned when the building is quiet: out of hours, at weekends or during the holidays.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Larger estates can be phased building by building around the people who use them.
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Petersfield simpler. The sooner the work is done, the simpler the job for a site in Petersfield.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep filter changes on time and recorded
- Flag stale or damp smells in the supply air
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
Different parts, different methods
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
AHU cleaning in Petersfield: local notes
Going by the FSA’s register, there are about 5 schools, colleges and universities and about 7 care, childcare and hospital premises serving food in Petersfield and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Petersfield Community Hospital is the nearest hospital, about under half a mile west of Petersfield. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. We cover Petersfield, about 50 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.
Workplaces around Petersfield station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Wherever a school like Petersfield Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Questions from Petersfield
Do you do school ventilation cleaning in Petersfield in the summer holidays?
Yes. The holidays are the usual time for school work. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Petersfield, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work overnight in Petersfield?
Yes, evening, overnight and weekend work is normal for us. The work in Petersfield can fit around your hours. Let us know the hours you’re closed and we will book within them.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How it works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. A few photos of the system and its access points help us plan a visit in Petersfield.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
