AHU cleaning in Englefield Green, done properly
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers dampers and louvres, supply and extract fans and internal panels, and people most often call us about debris and leaves in the fresh air intake and blocked condensate drains and slimy trays.
For a building near Englefield Green, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What the work involves, part by part
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- The size of the system
- Travel, parking and unloading
- A single visit or a regular plan
- Whether several sites go on one quote
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
To get a fixed quote, give us a ring on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
The process
Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away 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. In a place like Englefield Green, we fit the visit around your hours.
- We look at the unit and the plant area during the survey.
- 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.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area
Getting a quote
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Ventilation in Englefield Green buildings
There are about 12 schools, colleges and universities, about 7 hospitals, care homes and childcare premises and about 7 hotels, B&Bs and guest houses on the FSA’s food hygiene register across Englefield Green 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 21 miles out from central London, Englefield Green is part of the South East area we work across. Evening, overnight and weekend visits are all possible. The nearest hospital to Englefield Green is King Edward VII Hospital, about 3.6 miles north-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 Englefield Green Infant School and Nurseries has ducted ventilation, a half-term visit keeps the work out of lesson time.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

Common problems we fix in Englefield Green
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
If you notice any of these, it’s worth a diagnosis:
- Air handling units with blocked filters
- Condensate trays that will not empty
- Units that have only ever had filter changes
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like King Edward VII Hospital (about 3.6 miles north-west) to small clinics, depends on clean filters, coils and ducts.

What AHU cleaning can’t fix
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

- Mechanical faults with motors, belts or bearings
- Damaged coils beyond cleaning
If you’re not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer before booking.

Leave it or put it right?
Stuffy rooms and stale smells in a building in Englefield Green can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Light use slows the build-up but does not stop it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.
