- Problem: Air conditioner is not turning on
The air conditioner not turning on is a common problem that many household experience. This is not serious and can be fixed by following a few simple steps. If the air conditioning unit fails to turn on, it may be because the plug-in is lose or the thermostat is not set properly.
The first step that you need to take is checking to see if the aircon unit is connected properly to the electrical socket. If that is the case then you need to check the thermostat. Lower the thermostat temperature to about 5-10 degrees and see if that will fix the issue. You can also check to see if the circuit breaker has tripped or if the fuse has blown. Check the blower door and make sure that it is securely closed. Also check the condensate overflow tray to see if it has excess water. Some aircon usually have sensors that turn off the unit if water is full on the tray. If you have done all these adjustments and your air conditioner is still not turning on, then there is problem in the compressor or motor and need to be handled by an expert.
- Problem: Poor flow of air from cooling vents
Poor airflow from the vents usually occur when the ductwork is disconnected, crimped blocked by debris, leaves or from a dirty filer
Check the air filter and if it is dirty replace or clean it. In addition to that, inspect all ductwork and fix them if they are crimped or disconnected. Don’t forget to check the register damper on the vents and make sure that they are fully opened.
- Problem: The air conditioning unit does not dehumidify air
This problem usually occurs when you install an air conditioning unit that is too large for your house. If you notice that your aircon unit is turning on and off frequently, then it is because the system is too large for your house. Oversized aircon unit usually cool the air faster that how the thermostat can turn off the unit before humid air finds its way through the cooling unit in order to get humidified.
The only solution to this problem is to replace the coils and condensing unit with one that suits your house. You can also increase the air conditioning cooling load artificially by extending the air conditioner to your basement or garage.
- Problem: The air conditioner does not cool your home adequately
If your air conditioner is on and it has been set properly but it is still not cooling your house the way it used before, then you may have a dirty or blocked condenser.
Check the air outside of the air conditioning system and remove any debris or weeds that have accumulated around. Also check the filter and make sure that they are clean. If the filter is dirty, it restricts air to the evaporator coil causing it to freeze. Change the filter regularly especially if you have pets in your house.
In conclusion, not all problems require the attention of an aircon expert in order to be fixed. You can fix simple issues and let technician handle complicated ones. However, it is very important to note that most problems in air conditioning usually happen because of inadequate maintenance. To avoid future problems that can be costly, we advise that you ensure that your aircon unit is serviced regularly as recommended by the manufacturer.
