- Coils clogged with dust and debris
- Dust built up on fan impellers
- Air handling units never cleaned inside
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Report musty smells from the vents right away
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in Caversham
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for drain trays holding standing water and leaves and litter drawn into the unit, across internal panels, heating and cooling coils and supply and extract fans.
Around a town like Caversham, the buildings with ducted ventilation are typically offices, schools, surgeries and care homes. Their supply and extract ducts all gather dust over time.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Caversham: your questions answered
Do you cover Caversham for AHU cleaning?
Yes, we work in Caversham and the places around it. You can ring 0345 646 2711 or email us and let us know what needs doing.
Can you come to Caversham after we close?
Yes, nights and weekends are routine for us. The work in Caversham can fit around your hours. Your opening times are the first thing we ask for.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

Common problems we fix in Caversham
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
Healthcare buildings such as Royal Berkshire Hospital, about 1.9 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Caversham, yours matters too.

What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. We arrive in Caversham once you’ve closed and leave the site ready for the morning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Move anything stored near the system
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
How to get 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.

- How easy every part is to reach
- Any permits to work or inductions

What to send for a quote:
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- Problems your staff have spotted

Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then ring 0345 646 2711, or send details by email.
