How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

Why deal with it now?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. With notice, the visit to Shalford can be fitted around your bookings and events.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Ventilation in Shalford buildings
Food Standards Agency records list about 16 schools, colleges and universities and about 7 caring premises (care homes, nurseries and hospitals) registered as food businesses across Shalford and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. At about 28 miles from central London, Shalford sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included. Mount Alvernia Hospital is the nearest hospital, about 1.6 miles north of Shalford. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you run an office near Shalford station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near Shalford, clean ventilation matters as much to you as to a hospital like Mount Alvernia Hospital (about 1.6 miles north).

Your questions about AHU cleaning in Shalford
Do you clean school ventilation in Shalford in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 16 schools, colleges and universities with registered kitchens within about a mile and a half of Shalford. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work in villages like Shalford?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What information do you need?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure condensate is draining away
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Shalford can be planned properly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Move anything stored near the system

Advice
Signs you need AHU cleaning in Shalford
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Common reasons sites call us include:
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
School buildings such as Shalford Infant School are usually done in the holidays, so classrooms aren’t disturbed.
