Hampshire · Air handling unit cleaning
Air handling unit cleaning in South Harewood, Hampshire
AHU cleaning for businesses, landlords and public buildings in South Harewood. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
AHU cleaning for kitchens and businesses in South Harewood
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. 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 internal panels, filter sections and drain trays, and the jobs we see most are dust built up on fan impellers and air handling units never cleaned inside.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What AHU cleaning looks like in South Harewood
The FSA’s food hygiene register lists about 3 schools, colleges and universities with registered kitchens or food service within about 1.5 miles of central South Harewood. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Andover War Memorial Hospital is the nearest hospital, about 4.3 miles north-west of South Harewood. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as Wherwell Primary School are typically done in the holidays, so classrooms are not disturbed.

What affects the quote in South Harewood
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Site requirements such as sign-in and permits
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The postcode and the type of business
- Wide pictures of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to South Harewood.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Move anything stored near the system
- Agree a time when the area can be out of use
How to get a quote
For a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.

What we’re called out for in South Harewood
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
If you run a surgery, dental practice or care home near South Harewood, clean ventilation matters as much to you as to a hospital like Andover War Memorial Hospital (about 4.3 miles north-west).
Before you book anyone

Common questions in South Harewood
Do you work in villages like South Harewood?
Yes, we work in villages as well as towns, and South Harewood is covered. Just mention lanes, gates or anything else about the site when you book.
Can you work in South Harewood outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in South Harewood doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
How long does an AHU clean take?
It takes one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Make sure condensate is draining away
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
