Why it’s worth doing now in Petham

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

About our AHU cleaning in Petham
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have dust-coated heating and cooling coils and dust built up on fan impellers, we can help.
In a village or hamlet like Petham, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Ventilation in Petham buildings
Petham is about 53 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included. The nearest hospital to Petham is Kent and Canterbury Hospital, about 3.4 miles north-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For schools like Petham Primary School, the holidays are the usual time to inspect and clean ventilation.

Honest limits
It’s worth knowing the limits before booking:
- Leaking heating or cooling coils
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Filter sections
Different parts, different methods
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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. Leave those to us.
Common problems we fix in Petham
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Signs it’s time to call us include:
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Drain trays holding standing water
Healthcare ventilation, from large hospitals like Kent and Canterbury Hospital (about 3.4 miles north-east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Exactly which parts of the system are covered
- Whether a survey comes first
- Whether VAT is included
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Don’t ignore odours coming through the grilles
- Keep the area around the fresh air intake clear
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Petham questions
Can ventilation in schools around Petham be cleaned out of term?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Petham, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711, or email photos, and we will fit the work in.
Can the work in Petham be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Petham can fit around your hours. Just ring 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Is Petham in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Petham.
Can you price the work without visiting?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. If pictures aren’t enough, we’ll survey first.
Does the AHU have to be shut down for cleaning?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
How much does AHU cleaning cost in Petham?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us.
