AHU cleaning in Aldershot, done properly
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Common call-outs are for coils clogged with dust and debris and air handling units never cleaned inside, on dampers and louvres, filter sections and heating and cooling coils.
In a town like Aldershot, ventilation cleaning typically means offices, schools, surgeries, care homes and leisure buildings. Their supply and extract ducts all gather dust over time.
Nothing is signed off by word of mouth: 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.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Ventilation in Aldershot buildings
Food Standards Agency data includes about 25 schools, colleges and universities, about 19 care, childcare and hospital premises and about 3 hotels and guest houses across Aldershot and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 4.7 miles north-west of Aldershot is Fleet Community Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Aldershot, about 34 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
School buildings such as Talavera Junior School are typically done in the holidays, so classrooms are not disturbed. Fleet Community Hospital, about 4.7 miles north-west, is the nearest hospital to Aldershot, and healthcare sites of every size need their supply air kept clean.
Aldershot is about 8 miles west of Guildford, in Hampshire. Across the GU11 area, we can carry out AHU cleaning at your premises. Our area takes in 683 places across Hampshire, large and small. Guildford is in our area too, about 8 miles from Aldershot.
AHU cleaning in GU11 and GU12 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Station Road, East Station Road and High Street and the roads around them. You will find Aldershot on the A323 and A325, which makes it straightforward for our technicians to reach for out-of-hours visits. Nearby, we also carry out AHU cleaning in Weybourne (1 mile south-west), Badshot Lea (1 mile south), Heath End (1 mile south-west), Tongham (1 mile south-east) and Hale (2 miles south-west). Within a short drive, we also cover Basingstoke (15 miles west), Farnborough (3 miles north), Fleet (4 miles north-west), Alton (11 miles south-west), Yateley (7 miles north-west) and Bordon (10 miles south-west).

Common questions in Aldershot
Can you come to Aldershot after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Aldershot needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you offer AHU cleaning in Aldershot?
Yes. We work across London and the South East, and Aldershot is part of that. To start, phone us on 0345 646 2711 or send us an email with a few photos of the system.
How much does AHU cleaning cost in Aldershot?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then give us a ring on 0345 646 2711 or email us.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
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.
How we price AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- How easy every part is to reach
- The number of sites or systems
- The condition we find in the survey
- How big the system is
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- A few general shots of the system
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Signs you need AHU cleaning in Aldershot
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Most sites get in touch after spotting something like this:
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
For workplaces around Aldershot station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Questions to ask before booking
- Whether a survey comes first
- What records you will receive afterwards
- If the quote is a fixed price or an estimate
- When they can work, and whether that is outside your opening hours
What a clean will not put right
It’s worth knowing the limits before booking:
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer.
What we work on in Aldershot
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Internal panels
Aftercare tips
To keep the system working properly between visits:
- Check the drain tray is emptying during routine visits
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
