What happens if it’s left?
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. The sooner the work is done, the simpler the job for a site in Lymington.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

AHU cleaning in Lymington
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. Common call-outs are for drain trays holding standing water and intake sections clogged with outdoor debris, across dampers and louvres, heating and cooling coils and drain trays.
For a school, surgery or office in Lymington, cleaning is planned around opening hours: evenings, weekends or school holidays.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the visit works
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 the rest is down to us. Afterwards, the area is left tidy and the written report follows. Photos taken on a phone are usually enough for us to plan a job in Lymington and give a fixed quote.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading

FAQs for Lymington
Do you cover Lymington for AHU cleaning?
Yes, Lymington is within the area we cover across London and the South East. You can ring 0345 646 2711, or email photos and let us know what needs doing.

Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
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.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Are you insured?
Yes. We carry full insurance, and we have been trading since 2009.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you need AHU cleaning in Lymington?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Keep an eye out for any of the following:
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
If you manage shops or offices close to Lymington Town station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Ventilation in Lymington buildings
Food Standards Agency records list about 8 schools, colleges and universities, about 14 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses registered as food businesses in and around Lymington, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Lymington’s nearest hospital, Lymington New Forest Hospital, is about 0.9 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Lymington Junior School are easiest to work in when pupils are away. Healthcare ventilation, from large hospitals like Lymington New Forest Hospital (about 0.9 miles north) to small clinics, depends on clean filters, coils and ducts.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Whether several sites go on one quote
- Site rules, permits and inductions
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
- When the site is open and when it’s quiet
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
