September and October are traditional times of year for offices to service their air conditioning units after a summer of long and heavy use, and this is especially the case in 2023, as aircon systems across the country struggle under the pressure of an unprecedented late summer heatwave!

Servicing and maintaining your office air conditioning unit will help sustain its performance and energy efficiency and identify any early-stage issues that may escalate into a mechanical fault if not addressed. So, what are the main signs that your air conditioning system could benefit from professional attention?


Get In Touch


1. Weak Airflow 

If you notice that your air conditioning system is not blowing enough cool air or not reaching all parts of your office effectively, it could be a warning sign of a mechanical fault, or simply a ventilation issue arising from a clogged filter that needs cleaning. Whatever the case, don’t ignore weak airflow, as it can lead to increased energy bills and cause the system to work harder, eventually raising the risk of a breakdown.

2. Strange Odours

An unusual or pungent smell coming from your air-conditioning unit (sometimes likened to the aroma of a damp Labrador) is a sign that your system is due for a clean and service. The smell could arise from a variety of reasons, most commonly dirty filters, or mould growth inside the system, but it can also sometimes indicate a mechanical fault. These smells are not only unpleasant for workers but could also have health implications for staff with respiratory problems and allergies, so it’s worthwhile acting promptly when you notice something unusual.

3. High Humidity 

One of the roles of an office air-conditioning system is to regulate indoor humidity levels, so if your unit is not maintaining the ideal humidity, you and your employees may experience discomfort, notice the growth of mildew and mould around windowsills, and be more prone to allergies, colds, and other health issues. Maintaining adequate humidity levels also helps preserve the condition of computer equipment and furniture.

4. Unusual Noises 

Although most aircon systems emit a low-level background hum, they are designed to operate quietly with minimal disturbance to staff. If you hear strange noises such as banging, rattling, or grinding coming from your system, or even louder than normal operating sounds, it could indicate loose or worn parts. Acting promptly on this cue can often help you avoid significant damage to the system and lower your overall repair costs.
