Hampshire · Air handling unit cleaning
Upper Street AHU cleaning
We cover Upper Street for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports as standard.
- Dust-coated heating and cooling coils
- Drain trays holding standing water
- Air handling units never cleaned inside
Different parts, different methods
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
About our AHU cleaning in Upper Street
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, once the unit has been shut down and isolated. The work covers internal panels, filter sections and heating and cooling coils, and the jobs we see most are plant that needs cleaning after a refit and dirty coils holding back the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system help us make the most of a visit to a place like Upper Street.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Clear the space around the work
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- The times the site is available
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What we need to know
You do not need the technical terms. It helps if you can send:
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, call us on 0345 646 2711 or drop us a line.
Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It does not solve:
- Leaking heating or cooling coils
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before you book.

What else we do in Upper Street
Common problems we fix in Upper Street
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
The symptoms we’re asked about most are:
- Dirty filters cutting the airflow
- Odours coming through the supply air
- Dirty fans and fan housings
- Units that have only ever had filter changes
Salisbury District Hospital, about 5.5 miles north, is the nearest hospital to Upper Street, and healthcare sites of every size need their supply air kept clean.
Comparing quotes
- When they can work, and whether that’s outside your opening hours
- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
- Whether a written report and photos are included
In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
