AHU cleaning in Lucas Green

What affects the cost of AHU cleaning

The price is fixed before any work begins. It takes into account:

  • The condition we find in the survey
  • Any permits to work or inductions
  • When the work can happen, such as evenings, overnight or weekends
  • Whether we need access equipment or extra panels

Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

Helping us quote

To help us quote quickly, please include:

  • A few general shots of the system
  • Detail shots of panels, filters and grilles
  • The roof, plant room or outside wall the system runs to
  • Your last certificate, test record or report

If you need AHU cleaning in Lucas Green, give us a ring on 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.

AHU cleaning in Lucas Green

The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, drain trays and heating and cooling coils, and common reasons people get in touch are debris and leaves in the fresh air intake and drain trays holding standing water.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.

Duct Doctor has been trading since 2009, and we’re 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.

What happens on the day

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Lucas Green, lanes, gates and parking are worth mentioning in advance.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Tell us where we can park and unload
  • Let us know about permits to work or site inductions
  • Tell us the best time to work, such as after service or at a weekend

Ask for a quote

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Honest limits

To be straight with you, some problems need a different fix:

  • Breakdowns that need a mechanical engineer
  • Ductwork downstream of the unit, which is a separate clean
  • Leaking heating or cooling coils

If you are not sure, just ring 0345 646 2711 or send us an email and we’ll give you a straight answer.

What we work on in Lucas Green

  • Heating and cooling coils
  • Internal panels
  • Dampers and louvres
  • Filter sections
  • Drain trays
  • Supply and extract fans

Common problems we fix in Lucas Green

No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.

Most sites get in touch after spotting something like this:

  • Dust-coated heating and cooling coils
  • Debris and leaves in the fresh air intake
  • Odours coming through the supply air
  • Dirty filters cutting the airflow

Wherever a school like Bisley CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What your quote should include

  • Whether they’re fully insured
  • What’s included in the scope, part by part
  • If they look at the system before pricing
  • How areas they cannot reach will be recorded

In-house cleaning or a specialist?

Keep a record of what your team does. 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 cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

Can you quote from photos?

In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.

Do you offer emergency callouts?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

Do you do ventilation duct cleaning too?

Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.

Is there a report after cleaning?

Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

Rooftop and plant room units
