AHU cleaning in Frostlane, done properly
Where a building in Frostlane has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have dust built up on fan impellers and condensate trays that won’t empty, we can put it right, from filter sections, supply and extract fans and drain trays onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. It’s simpler to plan the work at Frostlane now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

Frostlane questions
Can you clean school ventilation in Frostlane during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Frostlane. Just call 0345 646 2711 or email us with your term dates and we will plan around them.
Do you work at weekends in Frostlane?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Is Frostlane in your area?
Yes. Frostlane is part of the area we cover, as part of our area across London and the South East.
Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
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.

What AHU cleaning looks like in Frostlane

Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Frostlane, the closest hospital is Royal South Hants Hospital, roughly 4 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to 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 do not reach the grease that builds up further in. That part needs specialist access and equipment.
When something else is needed
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- A system that’s undersized for the building
- Controls and BMS settings that run the unit
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Dampers and louvres
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Filter sections
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. For a village or hamlet like Frostlane, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend

Advice
What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- A single visit or a regular plan
- How easy every part is to reach
- The number of sites or systems
- Parking and loading at the site
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
To help us quote quickly, please include:
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from pictures; others need a survey. 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.
