- Coils clogged with dust and debris
- Odours coming through the supply air
How it works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In a small place like Rogate, the journey is planned ahead and the visit arranged around the site’s hours.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

AHU cleaning in Rogate, done properly
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you are dealing with dust-coated heating and cooling coils and air handling units with blocked filters, we can put it right, from filter sections, internal panels and supply and extract fans onwards.
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.

Why deal with it now?
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 Rogate simpler. Out of sight is the usual reason a rural system goes too long without attention.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

What else we do in Rogate
How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Questions from Rogate
Is AHU cleaning available in Rogate?
Yes, we work in Rogate and the places around it. You can ring 0345 646 2711 or drop us a line and tell us what needs doing.
Can the work in Rogate be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just phone us on 0345 646 2711 or email us with your opening times and we will plan around them.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you quote from photos?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. If pictures are not enough, we will survey first.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
How long does it take to clean an air handling unit?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can ring 0345 646 2711 or email us to plan it.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Does the AHU have to be shut down for cleaning?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- The times the site is available
- A single visit or a regular plan
- Site requirements such as sign-in and permits
- The number of sites or systems
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
Helping us quote
To speed up the quote, send us:
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
For a fixed quote, call us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
Rogate buildings and their air
Rogate is about 47 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included. Rogate’s nearest hospital, Petersfield Community Hospital, is about 4 miles west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Wherever a school like Rogate CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Rogate is about 4 miles east of Petersfield, in Hampshire. Whether your site is in the middle of Rogate or further out, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building.

Do you need AHU cleaning in Rogate?
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
What we’re most often called out for:
- Leaves and litter drawn into the unit
- Stale or musty smells from the ventilation
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near Rogate, clean ventilation matters as much to you as to a hospital like Petersfield Community Hospital (about 4 miles west).

Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
