AHU cleaning in Hare Green
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for odours coming through the supply air and drain trays holding standing water, across dampers and louvres, filter sections and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
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 to hand when an insurer or inspector asks.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Keep the area around the fresh air intake clear
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents straight away
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
- Any permits to work or inductions
- The scale of the work
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Any previous report or certificate
Some systems can be priced from photos; 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 any work starts.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
When to call us in Hare Green
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Hare Green, that’s air they breathe for hours at a time.
Signs it’s time to call us include:
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
- Condensate trays that won’t empty
An inspection comes first for any ventilation job around Hare Green, so the cleaning matches what’s there.
Before booking anyone
- Whether the work can be done while the site is closed
- Whether the quote shows VAT
- How they set the interval to the next visit
- Whether they’re fully insured
When it’s something else
Some problems need a different service or another trade:
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
If you are not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.

What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How it 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. The timing of a visit to Hare Green is set by you, and the travel is our side of the planning.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Mention any parking or loading restrictions
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
