Don’t Sweat It: 5 Indicators That Your AC Needs Servicing

As the summer months approach, many of us rely on air conditioning to keep our homes and workplaces cool and comfortable. However, a poorly maintained AC can not only fail to keep us cool, but it can also lead to higher energy bills and costly repairs. Regular maintenance is essential to keep your unit working optimally and avoid potential issues.

In this article, we will discuss five signs that your AC needs servicing and what you can do to address them.

1. Poor Airflow

If you notice that your AC is not blowing air as well as it used to, it may be time to service it. Poor airflow can be due to clogged air filters, damaged ductwork, or a faulty fan motor. Clogged air filters can restrict air from entering the unit, making it work harder than it should. This can lead to higher energy bills and decreased efficiency. Damaged ductwork can leak air, causing the cooled air to escape before it reaches its intended destination.

On the other hand, a faulty fan motor can cause the AC to blow warm air instead of cool air. A technician can inspect these components and determine the best course of action to restore proper airflow.

2. Unpleasant Odours

If your AC is producing unpleasant odours, it may be time to service it. Foul smells can be due to mould or bacteria growth in the unit’s evaporator coil or air ducts. These microorganisms thrive in damp and dark environments, which are common in those that have not been adequately maintained. Inhaling mould or bacteria can cause respiratory problems, especially for people with allergies or asthma.

A technician can clean the AC’s components and recommend a suitable disinfectant to prevent future microbial growth.

3. Strange Noises

If your AC is making strange noises, it may be time to service it. Unusual sounds can be due to loose or worn-out components, such as fan blades, belts, or bearings. These components can vibrate or rub against each other, causing a rattling, squeaking, or grinding noise. Ignoring these sounds can lead to further damage and costly repairs. A technician can inspect the unit’s components and replace any faulty parts to prevent further noise.

4. Water Leakage

If you notice water leakage around your AC, it may be time to service it. Water leakage can be due to a clogged condensate drain line or a damaged condensate pump. The condensate drain line removes the excess water that forms during the unit’s cooling process. If this line gets clogged, the water can back up and overflow, causing water damage to your property. The condensate pump, on the other hand, pumps the water out of the AC.

If this pump is damaged, it can cause water to leak. A technician can unclog the drain line or replace the pump to prevent further water damage.

5. Higher Energy Bills

If you notice a sudden increase in your energy bills, it may be time to service your AC. Higher energy bills can be due to an inefficient unit that is working harder than it should. This can be caused by clogged air filters, dirty condenser coils, or a refrigerant leak. Clogged air filters can restrict airflow. Dirty condenser coils can also reduce their efficiency, making it work harder to remove heat from the air.


Regular maintenance is essential to keep your unit working optimally and avoid costly repairs. If you notice any of the above signs, it is best to contact a qualified technician to service your AC. They can inspect, clean, and repair any of its components as needed, ensuring that it is in top condition.
