AHU cleaning for sites in Cranleigh

Why act early in Cranleigh

A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s better to plan the work at a site near Cranleigh than wait for a failure.

We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we will talk you through it.

About our AHU cleaning in Cranleigh

An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you have condensate trays that won’t empty and intake sections clogged with outdoor debris, we can put it right.

In a smaller place like Cranleigh, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.

Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Cranleigh

Your quote is based on your site. We consider:

  • Where the site is and how we reach it
  • The condition we find in the survey
  • Access, including roofs, risers and ceiling voids
  • The scale of the work

Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.

Helping us quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • The paperwork from the last visit, if you have it
  • A few general shots of the system
  • Close-ups of filters, grilles, hatches or access panels
  • Any symptoms, from odd noises to smells or leaks

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

Managing agents and facilities teams in Cranleigh

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

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

Different parts, different methods

Drain trays

Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.

Filters

Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What happens on the day

Your staff do not 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 the rest is down to us. Afterwards, the area is left tidy and the written report follows. Visits to a place like Cranleigh are planned ahead, so we arrive with what the survey says the job needs.

  1. We start with a survey of the unit and a fixed quote for the work.
  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. Standing water and slime come out of the tray and the drain is checked.
  5. You get a TR19® certificate and a photo report.

How to prepare

  • Find the previous report, if there is one
  • Tell us about site rules, permits or sign-in
  • Mention any locked doors, roof access or ceiling voids

Related advice

Cranleigh: your questions answered

Can ventilation in schools around Cranleigh be cleaned out of term?

Yes, and it’s the easiest time to do it. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cranleigh. Tell us your holiday dates and we will book the visit for when the site is empty.

Can you get to a site in Cranleigh?

Yes. Cranleigh is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.

How much does AHU cleaning cost in Cranleigh?

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

Do you clean the ductwork as well?

Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.

What is TR19?

BESA’s ventilation hygiene 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.

How often should an air handling unit be cleaned?

There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.

Can you look after several sites?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

Which kinds of sites do you work on?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Between visits

No system stays clean for ever, but care slows the build-up. Our tips:

  • Report stiff or damaged access doors
  • Make sure condensate is draining away
  • File each AHU report in the maintenance log
  • Do not ignore odours coming through the grilles

Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
