How we handle AHU cleaning in Peper Harow
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. Typical jobs include plant that has been serviced but not cleaned and filters that are clogged or overdue, across supply and extract fans, dampers and louvres and heating and cooling coils.
For a building in or near Peper Harow, access is agreed in advance and the visit is planned around the journey.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the quote in Peper Harow
Your quote is based on your site. We consider:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- The size of the system
- Whether it’s a one-off visit or part of a schedule
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Asking for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- The site address and the type of premises
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or email us.
Do you need AHU cleaning in Peper Harow?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Common reasons sites call us are:
- Dirty coils holding back the airflow
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
Hospitals such as Milford Hospital (about 2.3 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Peper Harow are no different.
Questions to ask before booking
- Whether the quote shows VAT
- Whether inaccessible sections are listed on the report
- How they set the interval to the next visit
- Whether the price is fixed
Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Honest limits
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly.
Parts of the system we cover
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Drain trays
- Dampers and louvres
- Filter sections
What your team can do, and what needs us
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.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. It’s worth booking a check, because nobody sees inside a duct day to day.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.
