How we handle AHU cleaning in Lower Brailes

Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. We’re often asked to deal with air handling units with blocked filters and intake sections clogged with outdoor debris, on filter sections, dampers and louvres and heating and cooling coils.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.

The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What we’re called out for in Lower Brailes

Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.

The symptoms we’re asked about most include:

  • Fan sections that haven’t been cleaned in years
  • Drain trays holding standing water
  • Dirty coils holding back the airflow
  • Air handling units with blocked filters

Healthcare buildings such as Ellen Badger Hospital, about 3.5 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Lower Brailes, yours matters too.

What to look for in a quote

  • Whether the figure could change on the day
  • When the next visit should be, and why
  • Whether a written report and pictures are included
  • Whether VAT is included

Questions to ask before you book

Ventilation in Lower Brailes buildings

Lower Brailes’s nearest hospital, Ellen Badger Hospital, is about 3.5 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

If you manage a school such as Brailes CofE Primary School, ventilation cleaning is best booked for the holidays.

Managing agents and facilities teams in Lower Brailes

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

What affects the cost of AHU cleaning

The survey tells us what the work involves. The main factors are:

  • How big the system is
  • The condition we find in the survey
  • The times the site is available
  • Site rules, permits and inductions

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

Asking for a quote

When you call or email, it’s useful to have:

  • Close-ups of filters, grilles, hatches or access panels
  • Where the site is and what kind of site it is
  • When the site is open and when it’s quiet
  • The paperwork from the last visit, if you have it

To get a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.

Questions from Lower Brailes

Do you work in villages like Lower Brailes?

Yes, Lower Brailes is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.

Can you come to Lower Brailes after we close?

Yes. We work evenings, overnight and at weekends. That way a site in Lower Brailes doesn’t have to lose a day’s trading. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.

Which kinds of sites do you work on?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

What happens to the waste?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.

How often do AHUs need cleaning?

TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.

What if parts of the system cannot 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.

Which accreditations do you hold?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.

Do you offer emergency callouts?

Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.

What the work involves, part by part

Heating and cooling coils

Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.

Internal casing and panels

We open each section through its doors and close them securely when we are done, and check every one is shut.

Staff cleaning versus specialist work

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.

The process

The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. We agree a date with you, plan the drive to Lower Brailes and turn up when the site is quiet.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

How to prepare

  • Agree a time when the area can be out of use
  • Tell us where we can park and unload
  • Tell us about site rules, permits or sign-in

Ask for a quote

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, then send a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.

What happens if it’s left?

Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. With notice, the visit to Lower Brailes can be fitted around your bookings and events.

Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What you get with us

  • Work around your opening hours, with 24/7 emergency cover
  • Ventilation hygiene specialists since 2009
