If your business has an air conditioning unit, in order to get the best lifespan out of the system as possible, it is important to implement preventative maintenance measures. When things do go wrong however, it can be very helpful to know what can be done to fix problems. Whereas some issues will need professional help, from one of’s qualified air conditioning repair technicians; there are others that can be identified and solved on your own.

In the following post, we will look at five of the most common problems that can affect air conditioning units and how to troubleshoot them, before you start booking costly repairs.

Air Conditioner Stops Working

If the air conditioner is not working, the first thing you should check is the circuit breaker. If you find that the circuit breaker is set to the off position, switch it back on and then recheck the unit. If it breaks again, you will need to call a HVAC specialist out.

If the breaker is already in the on position and still not working, you need to make sure the system’s thermostat is set to the right level. Adjust it up or down to see if it works. If it is not switching in and out, you need to check the unit’s batteries and replace them with new ones. After that, if the system is still not working, you need to call a HVAC specialist.

Air Is Not Cooled

Sometimes, the problem can be that the air conditioning unit is operating but the air is not being cooled. In the first instance, you need to check the inlet filter. This is often blocked with debris and dust that can restrict the air-flow. So you need to make sure it is clean and clear. It is also wise to check the outside of the unit and remove any leaves or other vegetation that may be growing or collecting up around it.

If the inlet filter and the area around it is clear and clean, you should try turning the thermostat down to the lowest level. If cold air is not forced out of the air conditioner after doing this, it could mean that the thermostat is actually broken and needs to be replaced.

Air Cooled Unevenly

If you notice that some rooms are cooler or warmer than others, it could mean that there are leaks in the ductwork that supplies to the airflow to specific rooms. Although an HVAC specialist can confirm this, before you call anyone out, check that the rooms that feel warmer than others are not because of the level of sun they are exposed to. Thermal blinds can be used to alleviate this heat source and can help to balance the temperatures between rooms.

Water Dripping From The Air Conditioner

Water that is leaking from your air conditioner may simply be caused by blockages in the condensate drain pipe. To solve this, follow the recommendations by the manufacturer to remove and clean this pipe.

If the water is caused by ice that has formed on the coils, it could be caused by a blocked filter that is restricting the air-flow. In this case, you need to turn the unit off to allow the coil to defrost and then call out an HVAC engineer.

Unusual or Excessive Noise

If your air conditioner starts to make some unusual and excessive amounts of screeching noises, this may be an indication of motor problems. You need to refer to the manufacturer’s recommendations for lubrication maintenance.

If there is a clanging noise, it may mean there is a more serious issue with the motor and it may require professional investigation, whereas if it is a flapping noise, this may mean that there is debris trapped in the fan blades. You need to turn it off and then check.
