AHU cleaning in Dial Post, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include coils clogged with dust and debris and air handling units with blocked filters, on filter sections, internal panels and heating and cooling coils.
Somewhere as small as Dial Post, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Common questions in Dial Post
Can the work in Dial Post be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Dial Post doesn’t have to lose a day’s trading. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
Is Dial Post in your area for AHU cleaning?
Yes, we work in Dial Post and the places around it. Get in touch with the details and we’ll arrange a survey.
How long does an AHU clean take?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What information do you need?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
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.
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.
When something else is needed
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Mechanical faults with motors, belts or bearings
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.

Aftercare tips
Once we’ve finished, these simple steps help:
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
- Don’t store bins or materials near the intake
- Make sure condensate is draining away
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Dial Post before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
- Clear loose items from the work area

Advice
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- The condition we find in the survey
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- The size of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- 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
- Detail shots of panels, filters and grilles
- The site address and the type of premises
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
