1.Air Conditioner not cooling properly
We buy an air conditioner with the sole aim of getting a cooling effect once it has been switched on. Regardless of the speed that it has, a good air conditioner should cool well in order for it to maintain comfortable temperature levels. If your Air conditioner is not cooling properly then the following reasons might be behind it.
- Undersized air conditioner
Buying an air conditioner based on the money that you have rather than the space available in your room is one of the main reasons behind your AC not cooling properly. When you install a small AC in a big room, it will be difficult for it to offer the cooling effects especially during sunny days. Making sure that you have the correct size of air conditioner for your room will help in solving this problems in air conditioners.
- Direct Sunlight on air conditioner outdoor unit
When the outer part or outdoor unit of your air conditioner is installed facing the sun directly, it will end up limiting the cooling effects of your AC. An air conditioner is specifically set to function in a given temperature and any increase or decrease in temperature will change how it operates. If the temperature surrounding the AC goes beyond its optimum temperature, the level of efficiency will be reduced by a greater percentage. This will render the AC useless as it will not be able to efficiently offer cooling effects to your room. Low temperatures also have an effect in the way your AC operates as it tends to make the AC use a lot of electricity in cooling the house. The best way of solving this problems in air conditioners is installing your AC in a position that is not prone to high temperatures. for more info read “Reasons behind AC not cooling properly”.
2.Air conditioner blowing hot air
At some point, your air conditioner may end up blowing hot air instead of the normal cold air. This problem proves to be very irritating since it goes against the importance of installing an AC in your household. If this is the case, then you should try one of the following solutions that will make it effective again
- Thermostat fan setting
The setting of the thermostat may be the reason behind your AC producing hot air. Changing this setting from ‘on’ to ‘auto’ will definitely do the trick since it will make the AC blow cool air regardless of whether it has been cooled or not.
- Air Filter
A dirty or weak air filter will make the supply vents of the AC to release hot air into the room. This is
because a dirty air filter tends to block the flow of air to the air handler. Changing old air filters or cleaning them will make your AC function efficiently.
- Outside air unit
The outside air unit is constantly subjected to dirt or dust that may be blown by the wind and thus end up distracting the operation of your AC. Clean this unit on a regular basis and enjoy the cooling effects without problems in air conditioners.
3. Air Conditioner not blowing air
This is one of the most common problems associated with air conditioners. The air conditioner may at times stop functioning and thus make it difficult for air to be released by the supply vents. When this is the case, consider using one of the solutions given below:
- Thermostat temperature
If you do not correctly set the thermostat temperature, you will end up having an air conditioner that is not working. To make it work efficiently, you should ensure that the thermostat temperature is set at about 5 degrees below the temperature of the room.
- Air filter
A dirty air filter will end up blocking the flow of air and thus freeze your inside unit. Clean the air filters on a regular basis so that they may not pose any threat to the functioning of your air conditioner.
The main reason behind your air conditioner not blowing may be electricity. If electricity does not reach the air conditioner, it will end up not working since this is the driving force behind its operation. Ensure that there is a constant supply of electricity to the Ac so that it may serve the intended purpose.
4. Air conditioner running longer than expected
This problem is mostly connected with the thermostat of the air conditioner. When you place your electric devices such television and lamps close to the air conditioner, they will end up affecting the operation of the thermostat. Instead of detecting air from outside, the thermostat will end up sensing heat that is released by these appliance thus making the AC to run longer than expected. Try placing the AC far away from these appliances in order for you to solve this problem.
5. Leaky duct
This problems in air conditioners is mainly caused by poor or wrong installation of the air conditioner in your house. When a technician who is not qualified installs your air conditioner, they may end up putting in location that does not allow the smooth operation of the AC. This will result in a leaky duct or even low supply of air into the house. Ensure that you use qualified personnel when installing the AC in order to solve this problem.
6. Drainage problems
These problems in air conditioners mostly occur when the weather is humid. Humid weather conditions may end up clogging the condensate drain of your air conditioner thus resulting in drainage problems. Solving this problem is easily done by constantly checking on the condensate drain and removing any clog that may be formed.
