Air Conditioner Running But Not Lowering Temperature: Diagnosing the Problem

An air conditioner can do a lot to make you feel more comfortable, especially in your sleep. The cooling that it can provide will come handy when you are living in a place where it is usually hot. Like other appliances, however, it is not free from issues. It can have multiple problems that will affect its cooling performance.

While there are many issues that can be evident, one of the most common would be an air conditioner running but not lowering temperature. In this case, the unit will just keep on running and using electricity in the absence of making the space cool. Why is this happening? Read on and find out from the insights that I will be sharing below.

Air Conditioner Running But Not Lowering Temperature

Cause and Solution Essay

Dirty Filter

Like in the case of most problems in an AC, one of the first things that should be checked is the air filter. The main purpose of the latter is to get rid of contaminants and dirt that can clog the unit. When the air flow is constricted or clogged, the air will not end up cool, despite the fact that the unit is running.

The best way to prevent this problem is to make sure that the air filter will be changed regularly, which will depend on how often you use the air conditioner. In most situations, it will be best to replace the filter every one to two months.

Blockage of the Condenser

The condenser is one of the vital parts in ensuring the peak performance of an AC. For the condenser to work at its best, make sure that it is placed in an open area. Experts in the installation of air conditioners also suggest that there should be 12-inch clearance around the condenser to provide it with the room to breathe.

One way to address this problem is to see to it that the condenser coil has no surrounding vegetation. If it is crowded with plants and other obstacles, this can have a negative impact on its cooling capacity.

Damaged Ductwork

The ductwork is an important part of the air conditioner since it delivers and distributes the cool air in a room. If there are cracks or leaks, the appliance can suffer from inefficiency as it can run and waste energy in the absence of cooling.

Inspect the ducts from the outside unit of the AC. See to it that they are properly connected. In case of damage, sealing can do the trick. If it is beyond repair, the best option is to consider a replacement, which is best done with a helping hand from experienced technicians.

Wrong System Size

As common sense would dictate, the larger a room is, the more powerful the air conditioner should be. That being said, make sure that the AC has the right size for your needs. Keep an eye on the horsepower, among other technical details of the product. However, you also need to keep in mind that the more powerful the unit is, the more electricity it will consume.

Refrigerant Leaks

As many technicians would say, the refrigerant is important because it is the lifeblood of the cooling system. Its function is the absorption of excess heat from indoors and releasing it outdoors. This requires the refrigerant to be running in a constant cycle. This will not be the case if it is leaking. Make sure that there are no leaks to enjoy continuous cooling. Otherwise, the temperature will not lower.

Damaged Fan

The AC is able to blow cool air because of the combined effort of its different components, and that includes the fan and the fan motor. It will draw air from the condenser and will have it redistributed in the room in the form of cool air. If the fan is damaged, this will not be possible.

Wrong Temperature Setting

Sometimes, the problem can be as small as having the wrong setting of the thermostat. You simply have to turn the temperature lower so that it can cool the place quicker. Also, it can be because the thermostat is set to HEAT instead of COOL. Check the remote or the unit to be sure that the right setting has been inputted.

Conclusion

The discussions above showed some of the reasons for an air conditioner running but not lowering temperature. It could be as simple as setting the wrong temperature to an issue that is as serious as having damaged ductworks. Many problems can be solved on your own, but if it is serious, it is best to pay for professional services.
