Air handling unit cleaning in Wix, Essex
For air handling unit cleaning in Wix, one call is all it takes, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Dirty fans and fan housings

- Debris and leaves in the fresh air intake
What we do, step by step
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Wix before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Find the previous report, if there is one
- Clear the space around the work
- Let us know about permits to work or site inductions

AHU cleaning in Wix
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you’re dealing with dirty fans and fan housings and air handling units with blocked filters, we can put it right, from supply and extract fans, drain trays and filter sections onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What we are called out for in Wix
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Look out for any of the following:
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
If you manage a school such as Wix and Wrabness Primary School, ventilation cleaning is best booked for the holidays.

- Whether they’re fully insured

- Whether the quote is based on a survey or photos
How we price AHU cleaning
We do not publish a price list, because sites vary so much. What we look at:
- The times the site is available
- Parking and loading at the site
- How big the system is
- How easy every part is to reach
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
Why it’s worth doing now in Wix
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. If the system at a site near Wix fails, there may be nowhere nearby to move to.
The cost 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.
Why book with us
- A single point of contact for sites across the South East and London
- Trading since 2009
- Out-of-hours work and a 24/7 emergency line
- Every job surveyed first
See our cost guide and how to check a contractor.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Report water on the plant room floor
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
- Book the next check in line with the report
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Common questions in Wix
Can you get to a site in Wix?
Yes, we work in villages as well as towns, and Wix is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Wix be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Wix needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
