Signs you need AHU cleaning in Longparish
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch after spotting one of these:
- Condensate trays that will not empty
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
School buildings such as Longparish Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.
What your quote should include
- What hours they’ll be on site
- Whether they recommend a next date
- What happens if part of the system can’t be accessed
- What insurance they carry
AHU cleaning in Longparish
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers filter sections, internal panels and drain trays, and common reasons people get in touch are drain trays holding standing water and air handling units due a clean after building work.
In a village or hamlet like Longparish, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

For landlords and multi-site operators
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
What affects the quote in Longparish
The survey tells us what the work involves. The main factors are:
- How easy every part is to reach
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Where the site is and what kind of site it is
- A few general shots of the system
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
Between visits
Here’s the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Longparish questions
Can you come to Longparish after we close?
Yes, we can come after you close and finish before you open. The work in Longparish can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Longparish be done out of term time?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Longparish. Booking early in the term gives the best choice of holiday dates.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
What a clean won’t put right

What else we do in Longparish
What the work involves, part by part
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
What happens on the day
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 before work begins, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Longparish, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload
