How we handle AHU cleaning in Hatherden
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers drain trays, heating and cooling coils and supply and extract fans, and the jobs we see most are dust built up on fan impellers and air handling units due a clean after building work.
Work in a small place like Hatherden starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Do you need AHU cleaning in Hatherden?
Whatever surrounds a building in Hatherden, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
If you notice any of these, it’s worth a diagnosis:
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Dirty fans and fan housings
- Drain trays holding standing water
If you run a surgery, dental practice or care home near Hatherden, clean ventilation matters as much to you as to a hospital like Andover War Memorial Hospital (about 2.6 miles south).

Between visits
Simple habits between visits make a real difference. Our advice:
- Keep inspection doors on the unit in good order
- Diary the inspection date recommended in the report
- Keep the certificate and photo report with the plant records
- Don’t ignore odours coming through the grilles
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Hatherden, let us know and we will plan around it.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area 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.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system

FAQs for Hatherden
Is Hatherden within the area you cover?
Yes, we work in villages as well as towns, and Hatherden is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer AHU cleaning in Hatherden?
Yes, we work in Hatherden and the places around it. To start, ring 0345 646 2711 or email us with a few pictures of the system.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
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 pictures and any previous report.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
How we price AHU cleaning
Your quote is based on your site. We consider:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
What to send for a quote
Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- Problems your staff have spotted
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.
How the job changes from site to site
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Larger estates can be phased building by building around the people who use them.
