Your questions about AHU cleaning in Haslemere
Do you do school ventilation cleaning in Haslemere in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 6 schools and colleges on the FSA’s register within roughly a mile and a half of Haslemere, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you work in villages like Haslemere?
Yes, Haslemere is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Can you clean without disrupting the building?
Yes, if daytime working is not practical. Tell us when the unit can go off and we’ll work to that.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
AHU cleaning in Haslemere
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have plant that has been serviced but not cleaned and condensate trays that won’t empty, we can put it right, from internal panels, supply and extract fans and filter sections onwards.
Visits to a place like Haslemere are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Good records are part of the job. You get a written report with pictures after each 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 to hand when an insurer or inspector asks.

What AHU cleaning cannot fix
Before booking, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before booking.
What the work covers
- Heating and cooling coils
- Drain trays
- Internal panels
- Dampers and louvres
- Filter sections
- Supply and extract fans
Common problems we fix in Haslemere
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
Healthcare buildings such as Haslemere and District Hospital, about 0.6 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Haslemere, yours matters too.
Questions to ask before booking
- What happens if part of the system cannot be accessed
- If the quote is a fixed price or an estimate
- Proof of accreditation you can verify
- What paperwork you get at the end
The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Tell us about any gates, ladders or locked plant areas at your site near Haslemere when you book.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend

What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.

Between visits
Simple habits between visits make a real difference. We recommend:
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- Do not ignore odours coming through the grilles
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
