AHU cleaning in Howe Street, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you are dealing with stale or musty smells from the ventilation and filters that are clogged or overdue, we can put it right, from heating and cooling coils, dampers and louvres and internal panels onwards.
In a village or hamlet like Howe Street, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Are you insured?
Yes. We’re fully insured, and the details are available on request.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What a clean won’t put right
We won’t sell you work that doesn’t address the problem, so here are the limits:
- A system that’s undersized for the building
- Building management system faults
- Dirty ducts beyond the unit itself
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before you book.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Howe Street and across Essex. Work can be phased by floor, building or site to keep disruption down.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What we are called out for in Howe Street
Whatever surrounds a building in Howe Street, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Intake sections clogged with outdoor debris
- Condensate trays that won’t empty
- Dirty fans and fan housings
Wherever a school like Chelmer Valley High School has ducted ventilation, a half-term visit keeps the work out of lesson time.

- Whether the figure could change on the day
Looking after it afterwards
After the visit, a few habits help the work last:
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Howe Street.
- We survey the unit from pictures or on site and agree what’s included.
- 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.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area

Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Howe Street is calmer for everyone.
Kitchens, offices, schools and hospitals are all priced 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 will explain each part.

Different parts, different methods
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
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.
