About our AHU cleaning in Chertsey
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you’re dealing with rooms that smell stuffy when the system runs and intake sections clogged with outdoor debris, we can help, from supply and extract fans, heating and cooling coils and filter sections onwards.
In a place like Chertsey, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s better to plan the work at a site near Chertsey than wait for a failure.

How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
How we price AHU cleaning
Sites vary more than people expect. What affects the quote:
- How many systems or sites are involved
- The times the site is available
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Your opening hours and when the area is out of use
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or email us.
In-house cleaning or a specialist?
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.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Ventilation in Chertsey buildings
Food Standards Agency records list about 18 schools, colleges and universities and about 17 hospitals, care homes and childcare premises registered as food businesses across Chertsey and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1 mile south-west of Chertsey is Runnymede Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Chertsey, about 19 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
Hospitals such as Runnymede Hospital (about 1 mile south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Chertsey are no different. Workplaces around Chertsey station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as St Anne's Catholic Primary School are usually done in the holidays, so classrooms are not disturbed.

Between visits
After the visit, a few habits help the work last:
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Do not store bins or materials near the intake
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
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.
Common questions in Chertsey
Can ventilation in schools around Chertsey be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Chertsey, the Food Standards Agency lists about 18 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711 or email us, and we will fit the work in.
Can you come to Chertsey after we close?
Yes, nights and weekends are routine for us. It means the site in Chertsey keeps running as normal. Just phone us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. We will ask for anything else we need.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Do you work in Chertsey?
Yes. Our technicians work in Chertsey, within the South East and London area we cover.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Tell us when your site near Chertsey is quiet and the visit will be booked for then.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
