Common problems we fix in Rudmore
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Keep an eye out for any of the following:
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
For schools like The Flying Bull Academy, the holidays are the usual time to inspect and clean ventilation.

How we handle AHU cleaning in Rudmore
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, dampers and louvres and drain trays, and the jobs we see most are air handling units due a clean after building work and air handling units with blocked filters.
In a place like Rudmore, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Tell us when your site near Rudmore is quiet and the visit will be booked for then.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Common questions in Rudmore
Can you get to a site in Rudmore?
Yes, we work in villages as well as towns, and Rudmore is covered. The journey is planned ahead, so a few details about the route help.
Can you work in Rudmore outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Rudmore keeps running as normal. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Can you price the work without visiting?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If photos aren’t enough, we’ll survey first.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Report stiff or damaged access doors
- Change filters on schedule and log each change
- Report musty smells from the vents straight away
- Don’t store bins or materials near the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Leave it or put it right?

Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.

What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and 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.
