- Dirty coils holding back the airflow
How we handle AHU cleaning in Hainault
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers heating and cooling coils, filter sections and supply and extract fans, and the jobs we see most are units that have only ever had filter changes and debris and leaves in the fresh air intake.
In a smaller place like Hainault, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. When a site near Hainault shuts unexpectedly, the people who rely on it notice at once.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. A site near Hainault typically has room to park, so the questions are about access to the system and your hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
- Tell us where we can park and unload
Getting a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What else we do in Hainault
Different parts, different methods
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
What affects the quote in Hainault
The quote reflects the site in front of us. We take into account:
- How big the system is
- How easy every part is to reach
- Parking and loading at the site
- Site rules, permits and inductions
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
What to send for a quote:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- The times we could work without disrupting the site
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Clear leaves and litter away from the intake
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
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 problems we fix in Hainault
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
These are the problems we see most often:
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
- Drain trays holding standing water
Classrooms and halls at schools such as Limes Farm Junior School are easiest to work in when pupils are away.
