About our AHU cleaning in Oak Corner
If the units serving a building in Oak Corner 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 filter sections, heating and cooling coils and drain trays, and the jobs we see most are dust-coated heating and cooling coils and dirty filters cutting the airflow.
For a building in or near Oak Corner, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Oak Corner, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
How to get a quote
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
How we price AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- Parking and loading at the site
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What a clean will not put right
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.

FAQs for Oak Corner
Can you clean school ventilation in Oak Corner during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Oak Corner. Send us your term dates when you ring 0345 646 2711, or email photos, and we’ll fit the work in.
Is Oak Corner within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you work evenings or weekends?
Yes, if daytime working isn’t practical. Tell us when the unit can go off and we will work to that.
What if parts of the system can’t be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
How long does it take to clean an air handling unit?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, including evenings or weekends.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Multi-site and managed buildings
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.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Signs you need AHU cleaning in Oak Corner
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Keep an eye out for any of the following:
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Condensate trays that won’t empty
In Oak Corner, we look inside the system before deciding what needs cleaning.
