AHU cleaning near Lower Horncroft

AHU cleaning in Lower Horncroft, done properly

Coils are where a lot of the dirt ends up. 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 aren’t flattened. The work covers heating and cooling coils, dampers and louvres and supply and extract fans, and the jobs we see most are units needing a clean before a new tenant or handover and coils clogged with dust and debris.

Somewhere as small as Lower Horncroft, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

FAQs for Lower Horncroft

Can you clean school ventilation in Lower Horncroft during the holidays?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Lower Horncroft. Booking early in the term gives the best choice of holiday dates.

Can you work in Lower Horncroft outside opening hours?

Yes. We work evenings, overnight and at weekends. The work in Lower Horncroft can fit around your hours. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.

How much does AHU cleaning cost?

It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711, or email photos with the site type, opening hours and a few pictures.

What do you do with what you remove?

It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

What is TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Do you cover Lower Horncroft?

Yes. We work in Lower Horncroft and across West Sussex, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form.

Can one contract cover all our sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.

Can you quote from photos?

Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. If photos aren’t enough, we will survey first.

For landlords and multi-site operators

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.

What we are called out for in Lower Horncroft

Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.

Common reasons sites call us include:

  • Intake sections clogged with outdoor debris
  • Air handling units never cleaned inside
  • Air handling units due a clean after building work
  • Dust-coated heating and cooling coils

For buildings in and around Lower Horncroft, TR19® Air cleaning starts with an inspection.

Questions to ask before booking

How we price AHU cleaning

The price is fixed before any work begins. It takes into account:

  • One-off work versus a regular cycle
  • Whether we need access equipment or extra panels
  • Site requirements such as sign-in and permits
  • Travel, parking and unloading

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • The paperwork from the last visit, if you have it
  • Where the site is and what kind of site it is
  • Wide pictures of the system and the area around it
  • Any symptoms, from odd noises to smells or leaks

Want a quote for AHU cleaning? Please give us a ring on 0345 646 2711 or send us an email with a few details about the site. We will explain what we’d do and send a fixed quote before anything is booked.

What your team can do, and what needs us

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

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 don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

The process

On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Seeing the system in photos first means the trip to Lower Horncroft can be planned properly.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After photos are taken and the certificate issued.

Before we arrive

  • Clear the space around the work
  • Find the previous report, if there is one
  • Agree a time when the area can be out of use

Advice

Leave it or put it right?

When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Lower Horncroft simpler. It’s worth booking a check, because nobody sees inside a duct day to day.

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.

Aftercare tips

Think of this as the after-treatment advice, short and simple:

  • Report stiff or damaged access doors
  • Store the TR19 paperwork where auditors can find it
  • Clear leaves and litter away from the intake
  • Diary the inspection date recommended in the report

Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.

Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
