Questions from Andover Down
Can you work in Andover Down outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Andover Down can fit around your hours. Your opening times are the first thing we ask for.
Can you do AHU cleaning in Andover Down?
Yes, Andover Down is within the area we cover across London and the South East. To start, give us a ring on 0345 646 2711 or drop us a line with a few pictures of the system.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply phone us on 0345 646 2711 or send us an email.
How we handle AHU cleaning in Andover Down
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers filter sections, heating and cooling coils and drain trays, and common reasons people get in touch are units that have only ever had filter changes and units needing a clean before a new tenant or handover.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What affects the quote in Andover Down
There’s no set price list, because sites vary so much. The quote depends on:
- One-off work versus a regular cycle
- Working hours and out-of-hours timing
- Travel, parking and unloading
- The size of the system
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- The paperwork from the last visit, if you have it
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 any work starts.

When to call us in Andover Down
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Drain trays holding standing water
- Stale or musty smells from the ventilation
Hospitals such as Andover War Memorial Hospital (about 2.6 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Andover Down are no different.
What your quote should include
- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Andover Down run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
Ask for a quote
For a fixed quote, call 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.
Related advice
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
