AHU cleaning in Preston Bissett, done properly
Where a building in Preston Bissett has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for units needing a clean before a new tenant or handover and drain trays holding standing water, on heating and cooling coils, supply and extract fans and drain trays.
Work in a small place like Preston Bissett starts with agreeing access and timings.

Preston Bissett questions
Do you work in villages like Preston Bissett?
Yes. Villages and rural sites across the South East are part of our work, Preston Bissett included. The journey is planned ahead, so a few details about the route help.
Can you come to Preston Bissett after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Preston Bissett doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
How long does an AHU clean take?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Out of sight is the usual reason a rural system goes too long without attention.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in pictures first means the trip to Preston Bissett can be planned properly.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend

Related advice
Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Other services in Preston Bissett
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Common problems we fix in Preston Bissett
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Clients typically contact us after spotting something like this:
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
- Dirty fans and fan housings
Ventilation work in and around Preston Bissett is risk-based: inspect, then clean what needs it.
