How we handle AHU cleaning in Sprig's Alley
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. Common call-outs are for air handling units never cleaned inside and stale or musty smells from the ventilation, across supply and extract fans, dampers and louvres and internal panels.
Somewhere as small as Sprig's Alley, 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.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Fixed quotes for AHU cleaning in Sprig's Alley
Sites vary more than people expect. What affects the quote:
- How easy every part is to reach
- One-off work versus a regular cycle
- The size of the system
- Travel, parking and unloading
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Sprig's Alley are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. Equipment tucked in a roof space or outbuilding near Sprig's Alley rarely gets looked at unless someone books it.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.

Sprig's Alley questions
Is Sprig's Alley within the area you cover?
Yes, Sprig's Alley is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you work in Sprig's Alley outside opening hours?
Yes, we can come after you close and finish before you open. The work in Sprig's Alley can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
When should our AHU next 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 do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
When something else is needed
It’s worth knowing the limits before booking:
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
- Problems with the unit’s controls or sensors
