Your air conditioner keeps your home comfortable on even the most sweltering days. But months of constant use can lead to issues that, if neglected, will result in costly air conditioning repairs. Keep your AC running smoothly throughout the summer by using the guide below to learn more about common AC problems.

A Guide to Summer Air Conditioner Problems

1. Refrigerant Leaks

Refrigerant plays an important role in the cooling process by absorbing heat from the air in your home to provide cool, conditioned air. Leaks are typically caused by cracks or holes in the coils that circulate the refrigerant.

A leak can cause the AC to blow warm air. If your vents are not blowing cool air, or you notice ice forming on your outdoor unit, you likely have a refrigerant leak that will require air conditioning repair. 

2. Worn-Out Fan

The AC’s fan is a key component for the airflow and heat release processes. Heavy use, faulty electrical wiring, or motor issues can cause the fan to wear down, which decreases airflow throughout your home.

Minor fan issues can sometimes be identified by the noises they make. For instance, if your air conditioner is making a clunking sound, it's often an indication that there is a loose or bent fan blade that is striking the inside of the indoor unit. If you hear a screeching sound, it typically means the fan belt is worn out and needs to be replaced. 

3. Clogged Condensate Lines

Your air conditioner creates moisture that is drained through a small pipe called the condensate line. Lack of maintenance and cleaning can cause clogs that lead to leaks and mold.

If your AC stops working or suddenly powers off, it might be the result of a clogged line. This is because many AC units have an overflow feature that automatically cuts the power before the drain pan overflows. Consider having your lines professionally cleaned to get the AC running again.
