About our AHU cleaning in Peartree Green
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We are often asked to deal with stale or musty smells from the ventilation and units that have only ever had filter changes, across heating and cooling coils, drain trays and internal panels.
Smaller buildings around Peartree Green often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Peartree Green buildings and their air
Going by the FSA’s register, there are about 35 schools, colleges and universities, about 51 care, childcare and hospital premises and about 18 hotels and guest houses serving food in and around Peartree Green, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Peartree Green’s nearest hospital, Royal South Hants Hospital, is about 1 mile north-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage shops or offices close to Woolston station, a TR19® Air inspection shows whether the ductwork needs cleaning. Hospitals such as Royal South Hants Hospital (about 1 mile north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Peartree Green are no different. For schools like Ludlow Infant Academy, the holidays are the usual time to inspect and clean ventilation.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Facilities teams in offices, schools and healthcare sites book us too in Peartree Green and across Southampton. Larger estates can be phased building by building around the people who use them.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In a smaller place like Peartree Green, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- 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
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
Advice
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
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 they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Peartree Green questions
Can you get to a site in Peartree Green?
Yes, Peartree Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can ventilation in schools around Peartree Green be cleaned out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 35 schools, colleges and universities with registered kitchens within about a mile and a half of Peartree Green. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we’ll fit the work in.
How long does an AHU clean take?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
When should our AHU next 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.
Can you clean without disrupting the building?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Fixed quotes for AHU cleaning in Peartree Green
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- The size of the system
- Site rules, permits and inductions
- The number of sites or systems
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, ring 0345 646 2711 or use the quote form 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 typically have a quote within one working day.
Why deal with it now?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Even a site near Peartree Green that’s only busy part of the week needs its system checked on a schedule.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.

Between visits
Once we’ve finished, these simple steps help:
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
