Questions from Clanfield
Can you work in Clanfield outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Clanfield keeps running as normal. Your opening times are the first thing we ask for.
Is AHU cleaning available in Clanfield?
Yes, we work in Clanfield and the places around it. A fixed quote usually follows within one working day of the survey details.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
How long will the unit be out of action?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so ring 0345 646 2711, or send details by email to talk it through.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
AHU cleaning in Clanfield
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers filter sections, drain trays and internal panels, and the jobs we see most are dirty fans and fan housings and air handling units with blocked filters.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning a trip to Clanfield ahead is easier for everyone than a rushed one.
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.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
- Keep inspection doors on the unit in good order
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Fixed quotes for AHU cleaning in Clanfield
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- A single visit or a regular plan
- How big the system is
- What state the system is in
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
Asking for a quote
When you contact us, it’s useful to have:
- Any previous report or certificate
- When the site is open and when it’s quiet
- The site address and the type of premises
- Any access panels or hatches you can see
If you need AHU cleaning in Clanfield, call us on 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Clanfield.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Common problems we fix in Clanfield
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Rooms that smell stuffy when the system runs
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
- Dust built up on fan impellers
Wherever a school like Clanfield Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.
