Air handling unit cleaning in Hart Plain, Hampshire
AHU cleaning for Hart Plain, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Drain trays holding standing water
How we handle AHU cleaning in Hart Plain
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers internal panels, dampers and louvres and drain trays, and the jobs we see most are dust-coated heating and cooling coils and dirty filters cutting the airflow.
Around a place like Hart Plain, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits
Here’s the after-treatment advice, in brief:
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Hart Plain questions
Can the work in Hart Plain be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Hart Plain needn’t be disturbed. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Do you cover smaller places like Hart Plain?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
How long does an AHU clean take?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, out of hours if needed.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What AHU cleaning cannot fix
It’s worth knowing the limits before booking:
- Building management system faults
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before booking.
What the work covers

How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A site near Hart Plain normally has room to park, so the questions are about access to the system and your hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a smaller place like Hart Plain, a site that has to close is felt quickly.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
