AHU cleaning near Sharpthorne

What staff can safely do

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

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, and that is where we come in.

AHU cleaning in Sharpthorne

All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you’re dealing with leaves and litter drawn into the unit and dust built up on fan impellers, we can help.

For a building in or near Sharpthorne, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

For insurers and inspectors, the record counts. That’s 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.

Between visits

Results last longer with the right care. Here’s what we suggest:

  • Stick to the filter change plan
  • Check the drain tray is emptying during routine visits
  • Store the TR19 paperwork where auditors can find it
  • Clear leaves and litter away from the intake

Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.

Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

Different parts, different methods

Fans and fan sections

Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.

Drain trays

The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

Landlords, agents and facilities managers

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

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.

Ventilation in Sharpthorne buildings

About 29 miles out from central London, Sharpthorne is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Sharpthorne’s nearest hospital, Queen Victoria Hospital, is about 4.5 miles north-east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.

Hospitals such as Queen Victoria Hospital (about 4.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Sharpthorne are no different. Wherever a school like West Hoathly CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Sharpthorne is about 4 miles south of East Grinstead, in West Sussex. Sites in Sharpthorne get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures. We cover 371 places across West Sussex, from busy centres to quieter spots. Our Brighton page covers sites nearby (17 miles or so).

Every address in RH19 is within our area for AHU cleaning, from the main roads to the quietest streets.

We also cover West Hoathly (1 mile west), Highbrook (2 miles south), Selsfield Common (2 miles north-west), Little London (2 miles south-west) and Birchgrove (3 miles south-east).

What happens on the day

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Sharpthorne, the date and timings are agreed with you well before the day.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. You get a TR19® certificate and a photo report.

Before we arrive

  • Dig out any earlier paperwork for the system
  • Allow time for equipment near the work to be turned off and cool down
  • Mention any locked doors, roof access or ceiling voids

Getting a quote

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.

What happens if it’s left?

Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A planned visit to Sharpthorne is easier to arrange than an emergency callout.

We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

Sharpthorne: your questions answered

Is Sharpthorne within the area you cover?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Is Sharpthorne in your area for AHU cleaning?

Yes, Sharpthorne is covered. You can call us on 0345 646 2711, or send details by email and tell us what needs doing.

Will we get paperwork for the AHU clean?

Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.

Do you look at the system first?

Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.

What do you do with what you remove?

It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.

What is TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.

What do you clean inside the unit?

All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.

How often should an air handling unit be cleaned?

It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.

How we price AHU cleaning

You’ll get a fixed price before work begins. It’s based on:

  • Site requirements such as sign-in and permits
  • Whether we need access equipment or extra panels
  • Whether it’s a one-off visit or part of a schedule
  • The condition of the system

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Asking for a quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • A few general shots of the system
  • The postcode and the type of business
  • Your opening hours and when the area is out of use
  • How we’d reach plant on a roof or in a plant room

There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or drop us a line.
