About our AHU cleaning in Hog Hatch
An air handling unit is the heart of a building’s ventilation: 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, which is why we clean the unit itself, not just the ducts. Common call-outs are for dust-coated heating and cooling coils and air handling units due a clean after building work, on drain trays, internal panels and heating and cooling coils.
Around a place like Hog Hatch, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
The sign-off is always in writing: a dated report with photos 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 affects the quote in Hog Hatch
Your quote is based on your site. We consider:
- Travel, parking and unloading
- How easy every part is to reach
- The condition of the system
- How many systems or sites are involved
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- The times we could work without disrupting the site
- A few general shots of the system
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Why it’s worth doing now in Hog Hatch
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Light use slows the build-up but does not stop it.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Common problems we fix in Hog Hatch
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’s the air they breathe for hours on end.
Most sites get in touch after spotting one of these:
- Air handling units due a clean after building work
- Odours coming through the supply air
- Dirty filters cutting the airflow
- Dirty fans and fan housings
Fleet Community Hospital, about 4.3 miles north-west, is the nearest hospital to Hog Hatch, and healthcare sites of every size need their supply air kept clean.

What else we do in Hog Hatch
Between visits
So the system stays in good health:
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. Getting to the system matters more than parking in a place like Hog Hatch, so let us know how to reach it.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet

FAQs for Hog Hatch
Can a school’s ventilation in Hog Hatch be done out of term time?
Yes, and it’s the easiest time to do it. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hog Hatch. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Can you get to a site in Hog Hatch?
Yes, Hog Hatch is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
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.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
