AHU cleaning in Otham, done properly
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers heating and cooling coils, supply and extract fans and internal panels, and common reasons people get in touch are dirty filters cutting the airflow and odours coming through the supply air.
For a building near Otham, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why act early in Otham
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. It’s better to plan the work at a site near Otham than wait for a failure.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

Managing agents and facilities teams in Otham
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Otham buildings and their air
Going by the FSA’s register, there are about 17 schools, colleges and universities and about 11 caring premises (care homes, nurseries and hospitals) serving food in Otham and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 2.8 miles north of Otham is KIMS hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. At about 33 miles from central London, Otham sits well inside the area we cover. The visit is fixed around your opening hours, not ours.

Otham questions
Do you clean school ventilation in Otham in the holidays?
Yes, and it’s the easiest time to do it. Around Otham, the Food Standards Agency lists about 17 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you get to a site in Otham?
Yes, we work in villages as well as towns, and Otham is covered. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or send us an email.
Can you quote from pictures?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
When to call us in Otham
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Look out for these warning signs:
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Plant that needs cleaning after a refit
School buildings such as Senacre Technology College are normally done in the holidays, so classrooms aren’t disturbed.
What your quote should include
- Whether the quote is based on a survey or pictures
- Whether the price is fixed
- How they set the interval to the next visit
- Proof of insurance
How the job changes from site to site
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.

The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a place like Otham are planned ahead, so we arrive with what the survey says the job needs.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
