Essex · Air handling unit cleaning
Air handling unit cleaning in Widford, Essex
For air handling unit cleaning in Widford, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Odours coming through the supply air
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
AHU cleaning in Widford
Where a building in Widford has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have blocked condensate drains and slimy trays and dust-coated heating and cooling coils, we can put it right.
Somewhere as small as Widford, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What else we do in Widford
Managing agents and facilities teams in Widford
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Make sure condensate is draining away
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Report water on the plant room floor
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What affects the quote in Widford
The diagnosis comes before the price. The main factors are:
- Site requirements such as sign-in and permits
- How many systems or sites are involved
- The condition we find in the survey
- Where the site is and how we reach it
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
We can often survey from photos. Try to include:
- The site address and the type of premises
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711 or send us an email.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Widford, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Widford questions
Can a school’s ventilation in Widford be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Widford. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you cover smaller places like Widford?
Yes, Widford is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How much notice do you need?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Common problems we fix in Widford
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Look out for any of the following:
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Dirty fans and fan housings
Wherever a school like Mildmay Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before you book anyone
- Whether they’re fully insured
- Whether the figure could change on the day
- Whether the quote is based on a survey or photos
- What’s included in the scope, part by part
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to Widford is calmer for everyone.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
Why book with us
- Every job surveyed first
- Work around your opening hours, with 24/7 emergency cover
- CHAS and SafeContractor accredited, with ISO 9001
- A fixed price before any work starts
