AHU cleaning across New Street

What your team can do, and what needs us

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.

How we handle AHU cleaning in New Street

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with odours coming through the supply air and air handling units never cleaned inside, we can help, from supply and extract fans, drain trays and dampers and louvres onwards.

Work in a small place like New Street starts with agreeing access and timings.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the job changes from site to site

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.

Internal casing and panels

Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.

How we price AHU cleaning

We do not publish a price list, because no two systems are the same. What we look at:

  • The condition of the system
  • Working hours and out-of-hours timing
  • How big the system is
  • Whether several sites go on one quote

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

What we need to know

We can often survey from pictures. The most useful are:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your last certificate, test record or report
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The postcode and the type of business

Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.

Looking after it afterwards

Aftercare is simple, and it makes the next visit easier:

  • Make sure the unit’s access doors open easily
  • Change filters on schedule and log each change
  • Keep the certificate and photo report with the plant records
  • Book the next check in line with the report

The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.

Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

The process

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like New Street.

  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, coils, fan section and casing are cleaned in turn.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. We close up the unit and send the certificate and before and after pictures.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Make sure someone can let us in and lock up afterwards
  • Allow time for equipment near the work to be turned off and cool down

How to get a quote

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711, or email photos.

Advice

What a clean will not put right

An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:

  • Breakdowns that need a mechanical engineer
  • Controls and BMS settings that run the unit
  • Coils that are corroded or leaking and need replacing

If you are not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer before you book.

What the work covers

  • Supply and extract fans

Leave it or put it right?

A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.

We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we will explain what it covers.

FAQs for New Street

Can a school’s ventilation in New Street be done out of term time?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of New Street. Tell us your holiday dates and we will book the visit for when the site is empty.

Do you work at weekends in New Street?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.

How much notice should we give?

Earlier is better, particularly for night and weekend visits. We usually quote within one working day, and there’s a 24/7 line for emergencies.

Can you quote from photos?

Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.

Can you clean the ducts connected to the AHU?

Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.

What happens if you can’t reach some of it?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Are you insured?

Yes. Duct Doctor is fully insured, and we can share the details when you need them.

What do you clean inside the unit?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
