AHU cleaning across Bell's Corner

AHU cleaning for kitchens and businesses in Bell's Corner

Where a building in Bell's Corner has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for plant that has been serviced but not cleaned and filters that are clogged or overdue, on supply and extract fans, heating and cooling coils and filter sections.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.

Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Leave it or put it right?

Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Planning a trip to Bell's Corner ahead is easier for everyone than a rushed one.

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. Ask for a fixed quote and we’ll explain each part.

How the job changes from site to site

Filters

Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.

Rooftop and plant room units

Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.

How we price AHU cleaning

You will get a fixed price before work begins. It takes into account:

  • The scale of the work
  • How many systems or sites are involved
  • The condition of the system
  • When the work can happen, such as evenings, overnight or weekends

You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711, or send details by email, and we will talk you through it.

What to send for a quote

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

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The site address and the type of premises
  • A few general shots of the system
  • The paperwork from the last visit, if you have it

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Landlords, agents and facilities managers

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

What we are called out for in Bell's Corner

Whatever surrounds a building in Bell's Corner, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.

Any of these means the system needs a check-up:

  • Filters that are clogged or overdue
  • Coils clogged with dust and debris
  • Leaves and litter drawn into the unit
  • Air handling units never cleaned inside

If you run a surgery, dental practice or care home near Bell's Corner, clean ventilation matters as much to you as to a hospital like Severalls Hospital (about 5.8 miles south).

What your quote should include

  • What’s included in the scope, part by part
  • Whether a survey comes first
  • Whether the figure could change on the day
  • What paperwork you get at the end

Our hiring checklist

The process

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Bell's Corner and turn up when the site is quiet.

  1. We survey the unit from photos or on site and agree what’s included.
  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. Standing water and slime come out of the tray and the drain is checked.
  5. A TR19® certificate and photo report follow the clean.

Getting ready for the visit

  • Find the previous report, if there is one
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Clear the space around the work
