Hillhead AHU cleaning
Need AHU cleaning in Hillhead? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
How we handle AHU cleaning in Hillhead
If the units serving a building in Hillhead have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you’re dealing with air handling units with blocked filters and dirty coils holding back the airflow, we can help, from drain trays, supply and extract fans and filter sections onwards.
For a building in or near Hillhead, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What a clean will not put right
A few issues sit outside what this work can do:
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer
- Building management system faults
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
What we work on in Hillhead
- Internal panels
- Filter sections
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Dampers and louvres
Do you need AHU cleaning in Hillhead?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that’s where slime and odours start.
Keep an eye out for any of the following:
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
- Intake sections clogged with outdoor debris
Healthcare buildings such as Coldeast, about 4.6 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Hillhead, yours matters too.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- Whether the quote shows VAT
- If they look at the system before pricing
- Whether a written report and pictures are included
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- Where the site is and how we reach it
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
You do not need the technical terms. Just send:
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
Want a quote for AHU cleaning? Please call 0345 646 2711 or send us an email with a few details about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.

Aftercare tips
To keep the system working properly between visits:
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

How it works
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 anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Hillhead, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Find the previous report, if there is one
- Mention any parking or loading restrictions
