Lower Pennington AHU cleaning
AHU cleaning in Lower Pennington from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Units that have only ever had filter changes
- Dirty filters cutting the airflow
- Leaves and litter drawn into the unit
How we handle AHU cleaning in Lower Pennington
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers dampers and louvres, drain trays and supply and extract fans, and the jobs we see most are air handling units due a clean after building work and dirty filters cutting the airflow.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Work can be phased by floor, building or site to keep disruption down.

What else we do in Lower Pennington
Ventilation in Lower Pennington buildings
Food Standards Agency data includes about 5 schools, colleges and universities, about 13 care, childcare and hospital premises and about 3 hotels and B&Bs in Lower Pennington and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. About 2 miles north of Lower Pennington is Lymington New Forest 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.
Hospitals such as Lymington New Forest Hospital (about 2 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lower Pennington are no different. Classrooms and halls at schools such as Priestlands School are easiest to work in when pupils are away.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. 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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
How we price AHU cleaning
A fixed price needs a few facts first. We check:
- Whether several sites go on one quote
- The scale of the work
- The times the site is available
- A single visit or a regular plan
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
When you call or email, it’s useful to have:
- Problems your staff have spotted
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
What we do, step by step
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Lower Pennington, the date and timings are agreed with you well before the day.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
How to get a quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711, or email photos.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
- Make sure condensate is draining away
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Lower Pennington: your questions answered
Do you cover smaller places like Lower Pennington?
Yes, Lower Pennington is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Lower Pennington be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Lower Pennington. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
What if parts of the system cannot be reached?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. With notice, the visit to Lower Pennington can be fitted around your bookings and events.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or send us an email, and we will explain what it covers.
