What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Where the site is and how we reach it
- Site rules, permits and inductions
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
What we need to know
When you contact us, it’s useful to have:
- Wide photos of the system and the area around it
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
The quickest way to a quote is to send pictures: 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 we can price many jobs without a visit.
AHU cleaning in Broxbourne
If the units serving a building in Broxbourne have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers internal panels, supply and extract fans and filter sections, and people most often call us about coils clogged with dust and debris and fan sections that haven’t been cleaned in years.
In a place like Broxbourne, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What AHU cleaning cannot fix
AHU cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- A system that’s undersized for the building
If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
Parts of the system we cover
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Drain trays
- Internal panels
- Supply and extract fans
Managing agents and facilities teams in Broxbourne
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
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 the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Everything the job in Broxbourne needs is worked out beforehand, from the survey.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system

Advice
FAQs for Broxbourne
Can the work in Broxbourne be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Broxbourne can fit around your hours. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you work in villages like Broxbourne?
Yes. Broxbourne is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
