AHU cleaning in Ockford Ridge, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers internal panels, heating and cooling coils and drain trays, and the jobs we see most are units that have only ever had filter changes and condensate trays that won’t empty.
In a village or hamlet like Ockford Ridge, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Ockford Ridge and across Surrey. Work can be phased by floor, building or site to keep disruption down.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Whether we need access equipment or extra panels
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
Before you ask for a quote, gather:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711, or send details by email.
Common questions in Ockford Ridge
Do you work in villages like Ockford Ridge?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can ventilation in schools around Ockford Ridge be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Ockford Ridge, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711, or email photos with the site type, opening hours and a few photos.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Other services in Ockford Ridge
What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work 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 Ockford Ridge, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

When to call us in Ockford Ridge
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
It’s time to book a visit if you see:
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
If you run a surgery, dental practice or care home near Ockford Ridge, clean ventilation matters as much to you as to a hospital like Milford Hospital (about 0.8 miles north-east).
What your quote should include
- Whether a survey comes first
- Whether the quote shows VAT
- What paperwork you get at the end
- How areas they can’t reach will be recorded
Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Ockford Ridge simpler. If the system at a site near Ockford Ridge fails, there may be nowhere nearby to move to.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or send details by email, and we will explain what it covers.
