AHU cleaning in Tillington

About our AHU cleaning in Tillington

Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Typical jobs include plant that needs cleaning after a refit and air handling units with blocked filters, on internal panels, heating and cooling coils and drain trays.

Somewhere as small as Tillington, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

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.

Landlords, agents and facilities managers

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

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 can quote for the whole system.

Aftercare tips

Aftercare is simple, and it helps at the next visit:

  • Stick to the filter change plan
  • Report water on the plant room floor
  • Look at the condensate drain whenever the unit is serviced
  • Diary the inspection date recommended in the report

When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.

Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

What AHU cleaning cannot fix

We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:

  • Leaking heating or cooling coils
  • Building management system faults
  • Ductwork downstream of the unit, which is a separate clean

If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before you book.

What we work on in Tillington

  • Supply and extract fans
  • Filter sections
  • Drain trays
  • Heating and cooling coils
  • Dampers and louvres

What we do, step by step

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Tillington before we set off.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. We clean out the drain tray and make sure it drains.
  5. We close up the unit and send the certificate and before and after pictures.

Preparing for the visit

  • Tell us where we can park and unload
  • Have your last certificate or report to hand

Advice

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

AHU cleaning in Tillington: local notes

Tillington’s nearest hospital, Midhurst Community Hospital, is about 4.6 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

If you run a surgery, dental practice or care home near Tillington, clean ventilation matters as much to you as to a hospital like Midhurst Community Hospital (about 4.6 miles west).

Tillington: your questions answered

Can you work in Tillington outside opening hours?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.

Is Tillington within the area you cover?

Yes. Villages and rural sites across the South East are part of our work, Tillington included. Just mention lanes, gates or anything else about the site when you book.

Can you come out in an emergency?

Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

Where does the waste go?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.

What does TR19 mean?

A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

How much does AHU cleaning cost?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.

How do you keep the site clean during the work?

Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.

Are you fully insured?

Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.

Why deal with it now?

Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Systems in rural buildings are often out of sight and out of mind.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

Common problems we fix in Tillington

No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.

Keep an eye out for these warning signs:

  • Dust built up on fan impellers
  • Units that have only ever had filter changes
  • Blocked condensate drains and slimy trays
  • Dust-coated heating and cooling coils

If you manage a school such as Petworth Cof E Primary School, ventilation cleaning is best booked for the holidays.
