What a dirty air conditioner really costs you
Every hour of operation pushes cubic metres of air through the filters and the coil of the indoor unit. Dust, textile fibres and moisture gradually build up. Air flows less freely, heat exchange deteriorates, and the compressor has to run longer to reach the same temperature.
You pay for this in three ways: higher electricity use, less healthy air (odours, mould in the condensate tray) and faster wear of components. Annual servicing brings the unit back to its normal operating conditions, whether it cools your home or your business.
Clean first, then measure: the two stages of the visit
Our air-conditioning technician starts by listening: how long the unit has been running, what you have noticed, how you use it. They then protect the floor and wall beneath the indoor unit.
Next comes the cleaning itself:
- removing and washing the filters;
- cleaning the coil, the blower wheel and the condensate tray;
- disinfecting with a product designed for air conditioners;
- checking the condensate drain and clearing it if needed;
- dusting the fins of the outdoor unit and checking its mounting.
The unit is then switched back on. Only at this point do readings make sense: they describe a clean air conditioner, so any abnormal value points to a real problem rather than mere dirt.
The readings we record
Depending on the type of unit, the technician measures:
- the return air temperature (air drawn from the room) and the supply air temperature;
- the temperature difference between the two, the first indicator of efficiency;
- the current drawn by the outdoor unit, compared with the manufacturer's data;
- circuit pressures where the situation calls for it;
- a leak check on the accessible joints.
Each value is explained to you in plain terms, on the spot. If the refrigerant circuit has to be opened, only a technician holding the refrigerant handling certificate does the work, and the operation is logged.
A clear report, followed by active vigilance
Before leaving, the technician gives you a service report: work carried out, readings taken, condition of each unit, setting tips. If a part shows signs of weakness, the report says so. No repair goes ahead without your written approval; if you wish, we will quote for a repair.
We then keep your unit's history. The following year, your new readings are compared with the previous ones, which reveals any slow decline. We also get back in touch before the season, and before any leak-check deadline: this is our active vigilance.
