Air handling unit cleaning in Southington, Hampshire
Need AHU cleaning in Southington? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
- Dirty coils holding back the airflow
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. In a small place like Southington, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system

How we handle AHU cleaning in Southington
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers internal panels, drain trays and supply and extract fans, and people most often call us about dust-coated heating and cooling coils and plant that needs cleaning after a refit.
In a village or hamlet like Southington, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Southington

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 work begins.

Common questions in Southington
Is Southington within the area you cover?
Yes. Southington is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Southington be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
How much does AHU cleaning cost in Southington?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or email us.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
What we’re called out for in Southington
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
What we’re most often called out for:
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
- Air handling units with blocked filters
- Drain trays holding standing water
Classrooms and halls at schools such as Overton Church of England Primary School are easiest to work in when pupils are away.
What to look for in a quote
- Whether VAT is included
- When the next visit should be, and why
- What’s included in the scope, part by part
- If the quote is a fixed price or an estimate
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- Any permits to work or inductions
- How big the system is
- Access, including roofs, risers and ceiling voids
- What state the system is in
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
Helping us quote
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. 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.
When something else is needed
Before booking, it helps to know what’s not included:
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
