AHU cleaning in Brickendon
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers heating and cooling coils, internal panels and drain trays, and people most often call us about blocked condensate drains and slimy trays and dirty fans and fan housings.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the quote in Brickendon
The price is fixed before any work begins. It’s based on:
- One-off work versus a regular cycle
- The condition of the system
- The size of the system
- Whether several sites go on one quote
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What to send for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- The site address and the type of premises
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, call us on 0345 646 2711, or send details by email.
Landlords, agents and facilities managers
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 send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Brickendon questions
Will you come out to Brickendon?
Yes. Villages and rural sites across the South East are part of our work, Brickendon included. Photos of the system and directions to the site help us plan the visit.
Can you do AHU cleaning in Brickendon?
Yes, Brickendon is within the area we cover across London and the South East. You can ring 0345 646 2711 or email us and let us know what needs doing.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you price the work without visiting?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Ventilation in Brickendon buildings
Brickendon is about 18 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. Hertford County Hospital is the nearest hospital, about 2.8 miles north of Brickendon. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For workplaces around Bayford station with mechanical ventilation, cleaning can be done in the evening or at weekends.

When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Problems with the unit’s controls or sensors
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
If you are not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Internal panels
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Heating and cooling coils
- Drain trays
What we’re called out for in Brickendon
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
- Plant that has been serviced but not cleaned
Healthcare buildings such as Hertford County Hospital, about 2.8 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Brickendon, yours matters too.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they’re fully insured
- Whether they recommend a next date
- Whether the quote is based on a survey or photos
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Brickendon run smoothly.
- 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.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Related advice
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Our emergency line runs 24/7, but a planned visit to Brickendon is calmer for everyone.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before we start.

Between visits
A little care between visits keeps the system in better shape. We recommend:
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
