Ventilation in Penton Corner buildings
Food Standards Agency data includes about 4 schools, colleges and universities and about 10 care, childcare and hospital premises in and around Penton Corner, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.5 miles east of Penton Corner is Andover War Memorial Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Portway Junior School, ventilation cleaning is best booked for the holidays.

AHU cleaning in Penton Corner
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. We are often asked to deal with units needing a clean before a new tenant or handover and filters that are clogged or overdue, on internal panels, heating and cooling coils and dampers and louvres.
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.
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.

What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A system that’s undersized for the building
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before you book.

FAQs for Penton Corner
Can ventilation in schools around Penton Corner be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Penton Corner. Just give us a ring on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Is Penton Corner within the area you cover?
Yes, Penton Corner is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can you quote from pictures?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. If pictures are not enough, we will survey first.
What happens if it’s left?
Stuffy rooms and stale smells in a building in Penton Corner can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. With notice, the visit to Penton Corner can be fitted around your bookings and events.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or send us an email for straight advice and a fixed quote.

Part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Penton Corner, let us know and we’ll plan around it.
- 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.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids
How to get a quote
For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Advice
How we price AHU cleaning
A fixed price needs a few facts first. We look at:
- The size of the system
- Site rules, permits and inductions
- The condition we find in the survey
- Where the site is and how we reach it
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- The postcode and the type of business
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
Signs you need AHU cleaning in Penton Corner
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
Healthcare buildings such as Andover War Memorial Hospital, about 1.5 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Penton Corner, yours matters too.
Before you book anyone
- Exactly which parts of the system are covered
- Whether the quote is based on a survey or photos
- Whether they’re fully insured
- Whether the work can be done while the site is closed
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
