How we handle AHU cleaning in Horspath
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you’re dealing with blocked condensate drains and slimy trays and air handling units never cleaned inside, we can put it right.
In a village or hamlet like Horspath, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
When it’s something else
A few issues sit outside what this work can do:
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer.

Signs you need AHU cleaning in Horspath
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
What we are most often called out for:
- Dust-coated heating and cooling coils
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
- Plant that needs cleaning after a refit
For schools like Horspath Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.

Horspath questions
Is Horspath within the area you cover?
Yes, we work in villages as well as towns, and Horspath is covered. The journey is planned ahead, so a few details about the route help.
Can you come to Horspath after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Horspath does not have to lose a day’s trading. Your opening times are the first thing we ask for.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Do you have insurance?
Yes. We carry full insurance, and we have been trading since 2009.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711 or email us.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How long will the unit be out of action?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so call 0345 646 2711 or use the quote form to talk it through.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send pictures, we can arrive in Horspath knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions

Leave it or put it right?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A fault that closes a site in a village like Horspath affects everyone who depends on it.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- The condition of the system
- Any permits to work or inductions
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
When you call or email, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- The site address and the type of premises
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then ring 0345 646 2711, or send details by email.
