AC maintenance in Belgium

Servicing cooling equipment is more than washing filters: fouled coils reduce heat transfer, so the unit runs longer and uses more energy without the user noticing a fault. The condensate route also deserves attention, because a partly blocked drain causes moisture damage long before water appears on the floor. We clean, measure pressures and temperatures, and compare them with the previous service.

AC maintenance: technician servicing an indoor air-conditioning unit

Our approach

Service with cleaning and measurement

On every service we follow the same order: record operation, clean coils and filters, test the condensate route, then log pressures and temperatures for the next comparison.

  1. 01

    Record the operation

    We measure the suction and discharge temperatures and compare them with the commissioning values. A smaller difference than before points to fouling or to a shortage of refrigerant.

  2. 02

    Clean the system

    Filters, indoor coil and outdoor coil are cleaned, and the fan checked. Coil fouling is the most underestimated cause of higher consumption at unchanged usage.

  3. 03

    Check the condensate route

    The drain is flushed and the fall checked so no water stands anywhere. A pump, where fitted, is tested with water rather than only checked for operation.

  4. 04

    Measure and report

    After cleaning, pressures and temperatures are remeasured and recorded. If the readings indicate refrigerant loss, we look for the leak instead of topping up and leaving.

Why servicing matters

Where an AC system quietly loses performance

Fouled coils reduce heat transfer. The unit runs longer for the same comfort without an obvious fault. Washing filters alone does not fix that if the fins themselves are dirty.

A partly blocked condensate drain causes moisture damage long before water sits on the floor. A pump that no longer draws also stays unnoticed until the tray overflows.

A refrigerant drop from a leak is sometimes masked for years by topping up. On a service visit we measure pressures and temperatures and name suspected loss instead of topping up quietly.

Servicing is the baseline. If readings point to a leak, odour or fault, we hand off to the right repair.

Signs to watch

When servicing should not wait

These signs point to fouling, condensate trouble or the start of refrigerant loss.

  • The unit cools more slowly or runs longer at the same usage.
  • A musty smell appears at start-up or while cooling.
  • You see moisture marks under the indoor unit or along the drain.
  • Energy use rises without you cooling more.
  • The outdoor coil is packed with dust, leaves or deposit.
  • Since the last visit there has been no comparison of readings.

Before we arrive

What you can prepare for the service visit

A short preparation speeds the visit and gives us a useful comparison with earlier readings.

  1. 01

    Clear space around the unit

    Move furniture or boxes from under and around the indoor unit so we can open it without damage.

  2. 02

    Note recent complaints

    Write down odour, lower airflow, water or higher consumption, and since when. That steers the measurements.

  3. 03

    Find earlier handover readings if you have them

    An install or previous service report helps. Without one we set a new baseline.

  4. 04

    Keep the outdoor unit accessible

    Clear the path to the outdoor unit so we can check the coil and the connections.

Clear pricing

What determines the price

Our call-outs start from €63.60 incl. VAT (6 % for homes over 10 years old, otherwise 21 %).

Service pricing depends on the number of units, access and whether you need periodic cleaning only or also parts. A single split is not priced like a multi-split with several indoor units.

You get the price for the planned visit in advance. If repair is needed, a separate quote comes before we replace parts.

Benefits

  • Coils cleaned, not just the filters washed out
  • Pressures and temperatures measured and compared with the last service
  • Condensate route flushed and checked for fall
  • Suspected refrigerant loss named rather than simply topped up
  • Electrical connections checked for overheating

What does AC maintenance cost?

Our call-outs start from €63.60 incl. VAT (6 % for homes over 10 years old, otherwise 21 %). The final price depends on the number of units, how easy they are to reach and the condition of the filters and coils. Any repair parts are agreed separately.

How often should an air conditioner be serviced?

For most homes a periodic visit each season or according to use is enough. Heavy use or dusty spaces may need a shorter interval. We match frequency to what the readings show.

Is filter cleaning the same as a service?

No. Washing filters helps, but a service also covers coils, condensate drainage, pressures and temperatures. That is how we separate fouling from refrigerant loss.

Do you top up refrigerant during maintenance?

Only if readings show a shortage, and after discussion. We look for the leak first. Topping up without leak tracing is named as a temporary measure.

How soon can servicing happen?

Timing depends on the area and availability. Water leaks or total failure are scheduled with priority when the diary allows. Our line is available 24/7.

Is there a warranty on replaced parts?

Up to 2 years warranty on labour; parts carry the manufacturer’s warranty.

When should you call an air conditioning technician straight away?

Some signs call for switching the unit off rather than letting it run: a burning smell, an unusual mechanical noise, water running from the indoor unit, ice that stays on the coil, or a breaker that trips on start-up. Turn the system off and leave it off: running it through those signs can make the fault worse.

Why Van Dijk Home

Topping up without finding the leak treats a symptom and leaves the problem. We clean the coils as well, measure pressures and temperatures against the previous service, and name refrigerant loss as a finding.
