AHU cleaning in Larkfield

About our AHU cleaning in Larkfield

An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. We’re often asked to deal with rooms that smell stuffy when the system runs and air handling units never cleaned inside, across internal panels, supply and extract fans and drain trays.

Somewhere as small as Larkfield, ducted ventilation is usually 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.

Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What we do, step by step

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Somewhere like Larkfield, lanes, gates and parking are worth mentioning in advance.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  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. A TR19® certificate and photo report follow the clean.

How to prepare

  • Arrange a key holder or contact on site
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us the best time to work, such as after service or at a weekend

What we’re called out for in Larkfield

Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.

Common reasons sites call us are:

  • Dirty filters cutting the airflow
  • Dirty coils holding back the airflow
  • Intake sections clogged with outdoor debris
  • Dust built up on fan impellers

For schools like Brookfield Junior School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before you book

  • Whether VAT is included
  • What paperwork you get at the end
  • When the next visit should be, and why
  • Whether the quote is based on a survey or pictures

Questions to ask before you book

Larkfield: your questions answered

Do you cover smaller places like Larkfield?

Yes, we work in villages as well as towns, and Larkfield is covered. A survey first, from photos or a visit, means we arrive with the right kit.

Do you do school ventilation cleaning in Larkfield in the summer holidays?

Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Larkfield. Booking early in the term gives the best choice of holiday dates.

How much notice do you need?

The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.

What if parts of the system can’t be reached?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Can you clean the ducts connected to the AHU?

Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.

Do you offer emergency callouts?

Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.

Can you price the work without visiting?

In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.

How long does an AHU clean take?

Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.

What affects the cost of AHU cleaning

There’s no set price list, because sites vary so much. The quote depends on:

  • The condition we find in the survey
  • One-off work versus a regular cycle
  • Parking and loading at the site
  • Site requirements such as sign-in and permits

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each 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 postcode and the type of business
  • Your last certificate, test record or report
  • Photos showing the whole system and its surroundings
  • Any access panels or hatches you can see

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

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

In-house cleaning or a specialist?

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between 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, which is where we come in.

Aftercare tips

To keep the system working properly between visits:

  • Check the drain tray is emptying during routine visits
  • Store the TR19 paperwork where auditors can find it
  • Stick to the filter change plan
  • Keep the area around the fresh air intake clear

The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.

Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
