AHU cleaning in Highams Park, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, supply and extract fans and filter sections, and the jobs we see most are air handling units with blocked filters and dirty fans and fan housings.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Highams Park.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Questions from Highams Park
Can ventilation in schools around Highams Park be cleaned out of term?
Yes, and it’s the easiest time to do it. With about 22 schools and colleges on the FSA’s register within roughly a mile and a half of Highams Park, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can the work in Highams Park be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Highams Park can fit around your hours. Let us know the hours you’re closed and we will book within them.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Fixed quotes for AHU cleaning in Highams Park
The survey tells us what the work involves. The main factors are:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. 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.
Signs you need AHU cleaning in Highams Park
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, building up layer by layer.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
Classrooms and halls at schools such as South Chingford Foundation School are easiest to work in when pupils are away.
What your quote should include
- If they look at the system before pricing
- Whether the quote shows VAT
- Whether inaccessible sections are listed on the report
- What’s included in the scope, part by part
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
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.
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 work takes one overnight shift for many single units, with bigger plant phased. Before any visit in Highams Park, we agree where the van can stop and how equipment reaches the system.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
Before we arrive
- Have your last certificate or report to hand
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
