An AC unit is a necessary utility for so many homeowners, especially for those who live in warmer climbs and who need to contend with the searing summer heat.
When it comes to residential air conditioning Sydney homeowners are likely to depend on their systems from December through to May, which is a long period of time that will see the unit be used heavily.
There are some very common issues which homeowners run into with these systems, and knowing what they will ensure that you can take action quickly when a problem occurs.
Frozen Coil
Within your AC unit there is a small coil which helps to refrigerate the air, in order to cool down a room.
This evaporator coil however will often drop to temperatures which are below freezing, either as a result of heavy use or because of lower temperatures outside.
Usually the coil thaws quickly after the unit is switched off, but continuous usage will see the coil stay frozen.
If this occurs it can lead to numerous issues in the system, which is why it something that you should seek to avoid.
Dirty Filters
The reason why homeowners are encouraged to regularly change their filters is that it often doesn’t take long before they become dirty and clogged.
If this should happen then the first problem is that dirty air will be pumped out of the unit and into the home, resulting in dust particles being inhaled and leaving their mark on furniture and items in the home.
If this continues then the filter can actually begin to block air coming through it, which can easily result in dust and dirt going back through the unit, resulting in a number of potential repair issues.
Thermostat Sensor Issues
Using a thermostat is the smartest and most economical way to use your AC unit, but problems can arise if the sensor is faulty.
What this will mean is that it is not able to sense the temperature and therefore will not switch on when it should, or it will switch on when it shouldn’t.
This kind of erratic behavior is often caused by something as simple as the sensor being bumped out of its position.
Alternatively, you may find that the sensor needs to be replaced.
Leakage
There are numerous reasons as to why your AC unit may begin to leak, either on the outside or the inside unit.
Deducing the source of the leak is something which a professional will be able to do for you, but it is up to you to spot leaks when they occur.
Leakage of refrigerant or water from your unit is something that should never happen, so if you see it be sure that you take action.
Even the slightest droplets of liquid coming from your AC system is likely to be a sign that there is something inside which isn’t operating as it should.
Be sure that you stay up to date with your maintenance of your AC unit in order to prevent this common issues from happening.
