AHU cleaning in Hailey, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you’re dealing with condensate trays that won’t empty and leaves and litter drawn into the unit, we can put it right, from filter sections, supply and extract fans and heating and cooling coils onwards.
In a village or hamlet like Hailey, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Hailey questions
Can you come to Hailey after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Hailey needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can you get to a site in Hailey?
Yes, we work in villages as well as towns, and Hailey is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply phone us on 0345 646 2711, or email photos.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Report stiff or damaged access doors
- Report musty smells from the vents right away
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Signs you need AHU cleaning in Hailey
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Keep an eye out for any of the following:
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Filters that are clogged or overdue
Healthcare buildings such as Hertford County Hospital, about 3.1 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Hailey, yours matters too.
What your quote should include
- How they set the interval to the next visit
- Proof of insurance
- If the quote is a fixed price or an estimate
- What happens if part of the system cannot be accessed
What a clean will not put right
Before you book, it helps to know what’s not included:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly.

AHU cleaning in Hailey: local notes
The FSA’s food hygiene register lists about 16 schools, colleges and universities and about 17 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in Hailey and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Hertford County Hospital is the nearest hospital, about 3.1 miles west of Hailey. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. Hailey, about 20 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Wherever a school like Roselands Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Hailey are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.

Different parts, different methods
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in Hailey and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
