Why AC not cooling properly? The air conditioner is a heat pump that basically absorbs heat from the air and then automatically transfer’s the heat to the outside unit known as the condenser. In case the condenser is dusty or have some debris, there will be no heat disperse thus resulting to the AC not functioning well. In most cases the air conditioning unit use substances that changes very quickly from gas to liquid and back again. These chemicals are the ones that transfer the heat from air inside and outside. The compressor, evaporator and the condenser are the three major parts that compose the AC unit. This is a very delicate and sensitive unit which requires extra care while handling.it also need maintenance to enable serve you longer. At times you may likely wonder why your AC is not cooling properly. At times it could be a technical problem and at times not. Listed below are some of the gathered and well researched reasons behind AC not cooling properly.
When the condenser coils taps dust it’s unable to dispel heat outside thus becomes less effective. In most cases this problem may occur when the air conditioner doesn’t cool enough and leading to the condenser coils becoming dirty and encumbered with rubble. This contributes and interferes with the cooling system making the coil strain and work harder to keep the room cool. Definitely dirty coils will not manage to keep the room cool.
The coolant flows through the evaporator coils and helps in cooling the hot air that flows over it, thus eventually sends the cool air into the room. In most cases you are likely to find,if the coolant is insufficient or the level of the coolant is too low, the AC will fail to cool properly leading to bigger problems.
Blocked Air Filter
The air filters blocks or gets clogged when the air conditioner fails to cool properly. This leads to the air not flowing through well and it lessens the process of cooling the air conditioner. The remedy is to either clean the air filter immediately or else you replace immediately for better cooling.
The compressor acts as the major part of an air conditioning unit which is sole responsible for cooling your room. It’s the gas-powered which icepacks the refrigerant using the refrigerant and the coolant. In case the compressor doesn’t function, the cooling cycle fails and doesn’t start and eventually the AC fails to cool.
Very High Temperatures
The AC works well at a stipulated temperature. In case the temperatures shoots too high and exceeds the normal limit, it interferes with the compressor making it not work effectively. Some fractuations of the temperatures at times too high might lead to compressor stopping completely.
Faulty thermistor sensors
This is a very important gadget which operates hand in hand with the compressor. It’s the mind of the compressor because it’s the one that is used to sense the room temperature and immediately communicates to the compressor to either stopping or starting the cooling cycle. So in case the thermostat has a defect the whole cooling process will be a total mess. This may lead to air conditioner cooling or not cooling continuously.
The other possible technical reason that may lead to AC not cooling might be defective or damaged parts of the compressor, bad thermistor, chocked capillary, faulty motor of indoor and out door, Condensers of compressor and fan motor, Power Relays and many more. It’s good to check and confirm if all the parts of the AC cooler are good.
Puny or Undersized AC
Purchasing or using a small AC against a very huge room will always give you challenges in cooling the room properly. The size of the AC should always be according to the size of the room for effective results. Always ensure you are using the correct and effective size of your AC against the room. Before you purchase the AC it’s advisable to contact a technician for advice on the best size that can suit your room.
This will help you avoid such issues and complications in future.
Damaged AC Remote
It’s always important to check on everything before concluding that your AC isn’t cooling properly. It could be your remote. At times the remote may fail to send signals to AC unit in order to change the temperatures thus leading and contributing to the AC not cooling properly.Th
is is just a minor problem hence the replacement of the remote will definitely solve the problem. Always handle and take good care of the remote and keep it away from dirt too.
Improper AC unit installation
It’s always good and advisable to check your installation carefully before you conclude that your AC isn’t working. Always try another installer to confirm and be sure that all is well. It could be the installation was incorrect or the units tend to be too big or too small for your home.Trying another technician will also work in case you doubt the first installer. Confirmation is also good.
Frozen Air Handler.
Check for frozen air handler, in case your AC is frozen it may cause the air to be too hot since the ice formed is causing and preventing the air from passing thus not cooling the room properly. Thus,not cooling the room properly. This prevents the air from being cooled and prevents the AC from moistening the air.
This prevents the air from being cooled and prevents the AC from moistening the air.
It’s advisable to switch the off your AC for at least 24hrs and let it cool to refrozen the air before using it again.
These are most common reasons behind AC not cooling properly, It’s advisable to always ensure you do regular maintenance to your AC so that in case a problem is detected earlier it gets fixed before causing more harm. Always keep close check on your condenser unit to ensure and maintain good airflow at all times. Clean your AC to remove dirt and debris for effective service at all times. some times differences between Aluminium coil and copper coil makes effects on AC not cooling issue.
