Book AHU cleaning in Barns Green

Common problems we fix in Barns Green

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.

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

  • Rooms that smell stuffy when the system runs
  • Dust-coated heating and cooling coils
  • Air handling units with blocked filters
  • Drain trays holding standing water

Healthcare ventilation, from large hospitals like Horsham Hospital (about 4 miles north-east) to small clinics, depends on clean filters, coils and ducts.

Before you book anyone

  • Whether VAT is included
  • Whether the price is fixed
  • When they can work, and whether that’s outside your opening hours
  • Whether inaccessible sections are listed on the report

Choosing a duct cleaning contractor

AHU cleaning for kitchens and businesses in Barns Green

The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you’re dealing with plant that has been serviced but not cleaned and air handling units with blocked filters, we can help, from supply and extract fans, dampers and louvres and drain trays onwards.

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.

We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the quote in Barns Green

The diagnosis comes before the price. We look at:

  • Any permits to work or inductions
  • How easy every part is to reach
  • Where the site is and how we reach it
  • The size of the system

The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.

Asking for a quote

Many jobs can be priced from pictures and some basics. Useful things to send:

  • The times we could work without disrupting the site
  • Your last certificate, test record or report
  • Detail shots of panels, filters and grilles
  • Photos showing the whole system and its surroundings

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Honest limits

In fairness, there are a few things this work will not fix:

  • Ductwork downstream of the unit, which is a separate clean
  • Airflow problems caused by the system’s design
  • Problems with the unit’s controls or sensors

If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

Where we work

  • Drain trays
  • Internal panels
  • Dampers and louvres
  • Heating and cooling coils
  • Supply and extract fans
  • Filter sections

The process

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Barns Green.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

How to prepare

  • Plan for cooking equipment or plant to be off before we arrive
  • Mention any parking or loading restrictions
  • Dig out any earlier paperwork for the system

Ask for a quote

Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Barns Green questions

Can the work in Barns Green be done at night or at weekends?

Yes, we can come after you close and finish before you open. It means the site in Barns Green keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

Will you come out to Barns Green?

Yes, we work in villages as well as towns, and Barns Green is covered. Photos of the system and directions to the site help us plan the visit.

How often should an air handling unit be cleaned?

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 do you need from me for a quote?

Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.

How far ahead should we book?

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

Do you offer maintenance contracts?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

How much does AHU cleaning cost?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.

Managing agents and facilities teams in Barns Green

When the building owner and the occupier are different, 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.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Part by part

Internal casing and panels

We open each section through its doors and close them securely when we are done before the unit is handed back.

Filters

Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
