What AHU cleaning looks like in Upper Froyle
Upper Froyle’s nearest hospital, Alton Community Hospital, is about 4 miles south-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. At about 42 miles from central London, Upper Froyle sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
School buildings such as Eggar's School are usually done in the holidays, so classrooms aren’t disturbed.

About our AHU cleaning in Upper Froyle
We clean air handling units for buildings in Upper Froyle and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers internal panels, drain trays and filter sections, and common reasons people get in touch are air handling units with blocked filters and plant that needs cleaning after a refit.
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 pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Different parts, different methods
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Common problems we fix in Upper Froyle
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Common reasons sites call us are:
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
- Drain trays holding standing water
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Upper Froyle, clean ventilation matters as much to you as to a hospital like Alton Community Hospital (about 4 miles south-west).

Fixed quotes for AHU cleaning in Upper Froyle
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
Helping us quote
When you call or email, it’s useful to have:
- Problems your staff have spotted
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, call 0345 646 2711 or drop us a line.
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Upper Froyle run smoothly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Honest limits
In fairness, there are a few things this work won’t fix:
- Building management system faults
- Coils that are corroded or leaking and need replacing
- A system that’s undersized for the building
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
What the work covers
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Filter sections
Aftercare tips
Once we’ve finished, these simple steps help:
- Report stiff or damaged access doors
- Look at the condensate drain whenever the unit is serviced
- Don’t store bins or materials near the intake
- Report musty smells from the vents right away
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Upper Froyle questions
Is Upper Froyle in your area for AHU cleaning?
Yes, Upper Froyle is covered. A fixed quote typically follows within one working day of the survey details.
Is Upper Froyle within the area you cover?
Yes. Upper Froyle is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
Can you clean without disrupting the building?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
