About our AHU cleaning in Broadford
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Typical jobs include leaves and litter drawn into the unit and dirty filters cutting the airflow, across dampers and louvres, supply and extract fans and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What staff can safely do
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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

Different parts, different methods
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
When to call us in Broadford
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
These are the problems we see most often:
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
Classrooms and halls at schools such as Shalford Infant School are easiest to work in when pupils are away.

The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Broadford, let us know and we will plan around it.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Clear the space around the work
- Have your last certificate or report to hand

What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- What state the system is in
- Working hours and out-of-hours timing
- The scale of the work
- Where the site is and how we reach it
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
What we need to know
Before you ask for a quote, gather:
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- The postcode and the type of business

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. If the system at a site near Broadford fails, there may be nowhere nearby to move to.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
