AHU cleaning near Little Canfield

What we’re called out for in Little Canfield

Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.

If you notice any of these, it’s worth a diagnosis:

  • Odours coming through the supply air
  • Units that have only ever had filter changes
  • Air handling units due a clean after building work
  • Dirty filters cutting the airflow

Healthcare buildings such as Herts and Essex Hospital, about 4.8 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Little Canfield, yours matters too.

What your quote should include

  • What hours they’ll be on site
  • When the next visit should be, and why
  • Exactly which parts of the system are covered
  • Whether VAT is included

About our AHU cleaning in Little Canfield

Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for air handling units with blocked filters and odours coming through the supply air, across filter sections, drain trays 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, where filters and drain trays get forgotten.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Multi-site and managed buildings

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. With shared responsibility, good records help everyone.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.

Filters

What’s on the filters is a good clue to what’s further in. We photograph them for the report.

FAQs for Little Canfield

Do you do school ventilation cleaning in Little Canfield in the summer holidays?

Yes. Half-terms and the summer break are the natural time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Little Canfield, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711, or email photos, and we will fit the work in.

Can you get to a site in Little Canfield?

Yes, Little Canfield is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.

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.

Do you work evenings or weekends?

Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.

What types of premises do you cover?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

What does TR19 mean?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

What should I send you?

The site address, the type of premises and your opening hours, along with a few photos and any previous report.

Does the AHU have to be shut down for cleaning?

Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.

Looking after it afterwards

Here’s the after-treatment advice, short and simple:

  • Keep inspection doors on the unit in good order
  • Look at the condensate drain whenever the unit is serviced
  • Note any water around the unit or leaks below it
  • Report musty smells from the vents straight away

When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.

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

Why deal with it now?

A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A fault that closes a site in a village like Little Canfield affects everyone who depends on it.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos.
