Air handling unit cleaning in Runwell, Essex

- Debris and leaves in the fresh air intake
How we handle AHU cleaning in Runwell
Where a building in Runwell has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you have debris and leaves in the fresh air intake and odours coming through the supply air, we can put it right.
In a smaller place like Runwell, 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Runwell questions
Can ventilation in schools around Runwell be cleaned out of term?
Yes, out-of-term visits are normal for schools. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of Runwell, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or send us an email, and we’ll fit the work in.
Can the work in Runwell be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Runwell keeps running as normal. Let us know the hours you’re closed and we will book within them.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where necessary.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Places near Runwell
What else we do in Runwell
What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Common problems we fix in Runwell
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us are:
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
Workplaces around Wickford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Before you book anyone
- When the next visit should be, and why
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
- What records you will receive afterwards
How it works
Every visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Runwell and bring what the job is likely to need.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- Travel, parking and unloading
- Whether several sites go on one quote
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
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 staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
