Common Air Conditioning Problems

The main symptons

Most day-to-day AC problems are caused by neglecting regular maintenance. We have have provided a list of the common problems we encounter below.

If you have any of these issues we can help, so please contact us to arrange an inspection, repair or service.

The two most common causes of your air conditioning system leaking is blocked drains or failed condensing pumps. Our expertly trained engineers will be able to quickly diagnose the cause of your issue and generally fix it in a very short period of time. We generally carry stock of the most common pumps in the market thus reducing your downtime.

Request Maintenance

Air conditioning system under performance is usually associated with dirty coils on indoor and outdoor units or a lack of refrigerant. Having a maintenance contract in place can significantly reduce call outs associated with this type of air conditioning problem as filters will be cleaned and in certain circumstances a refrigerant leak check is also carried out as part of our bespoke maintenance packages designed to prolong the life of your equipment.

Request Maintenance

As above the two most likely causes of condenser coils freezing is down to dirty coils or lack of refrigerant. As part of our maintenance package we will clean the outdoor condensing coil with industry standard condenser cleaner to ensure your system runs at optimum efficiency throughout the year.

Request Maintenance

If your AC unit is emitting unpleasant odours this is usually down to a lack of maintenance and or untreated / infrequently cleaned coils. In some circumstances this can also be due to a lack of ventilation within the room. It is important to remember that cassette and wall mounted air conditioning units only warm or cool the existing air and do not provide ventilation, so a lack of air changes in a room could contribute to bad odours.

Request Maintenance

Reduced airflow can be associated with something as simple as incorrect controls, louver failure or faulty fan motors. Its important to check that your controller is in the correct mode and the louver on the unit has opened the airways for the cool or warm air to escape. Our qualified engineers will be able to check the operation of the system and if necessary electrically test the function of the air conditioning unit.

Request Maintenance

The most common cause for rising energy bills is incorrectly set controls where the settings are set too high or two low. It is a common misconception that setting the controller down to 16 degrees will decrease the amount of time it takes to cool the room. Our air conditioning experts can discuss with you the most efficient way to control your air conditioning system. As part of our installation service we always ensure we provide a detailed handover to our clients to ensure they get the most out of their energy efficient air conditioning products.
