Dealing with a malfunctioning air conditioner isn’t a pleasant experience on a hot summer day. The summer season always comes with unbearable dry air and extreme heat. For this reason, you must inspect your AC unit to be sure it’s functioning as expected.

Understanding various air conditioning problems will help you deal with them before the hot summer weather sets in. Conducting regular AC maintenance will help you maintain comfortable temperatures within your home. However, in case of an AC unit issue, you may experience some unbearable indoor temperatures.

For severe air conditioning issues, you’ll need to contact a technician to help you diagnose and fix the problem. Additionally, you may choose to replace an old, malfunctioning AC unit, as it can cost you more on repairs.

The following article discusses various AC unit issues that can pop up during the summer months.

1. External Fan Malfunctioning

Your air conditioner could be malfunctioning due to damages resulting from foreign items entering into the outside casing. This could lead to bent fan blades, causing them to strike the casing as the fan rotates, resulting in damage. For this reason, it’s recommended that you install your condenser in a clear area to prevent the condenser fan from any damage.

2. Freon Leak

Low levels of Freon refrigerant lead to reduced efficiency of your AC unit. The refrigerant is responsible for absorbing heat from the warm air blown over the evaporator coils. In most cases, a low Freon level is a result of leaking evaporator coils.

For low refrigerant levels, you can try refills for the best results for your system. However, you’ll need to contact technicians to help you fix leaking evaporator coils. The technicians at Medcalf Heating & Cooling provide reliable and quality service.

3. AC Unit Turning On and Off Constantly

If you switch on your system and then, after running for a while, it turns off by itself, that’s something to worry about. This issue is normally known as short cycling.

Be sure to correct the issue as soon as you notice it, as it could lead to severe damages to your compressor. Additionally, this issue leads to increased utility bills. Your technician will help you fix the problem by installing a hard–start device.

Installing a smaller-sized air conditioner could be a primary cause of this problem. If this is the situation with your system, it could mean you’ll have to install another unit to fix the issue.

4. AC Unit Running Without Cooling

The main reason for this air conditioning problem is the electrical disconnection between the thermostat and your interior unit. Another cause of your system running without cooling your home could be a result of inadequate Freon levels. For best results, let an expert help you restore your system’s cooling ability.

5. Sensor Issues

Your AC unit uses a thermostat to control your indoor temperature levels. When not correctly placed or installed, it would be sensing different values from the desired ones. With different monitoring values, your cooling system will work but not as expected. Have your technician help you fix your thermostat issue for effective cooling.

6. Not Enough Cooling

Generally speaking, your air conditioner is made to handle a certain amount of load. Some summer days could be hot beyond what your system can handle, leading to inadequate cooling.

Additionally, installing an undersized AC unit could result in inadequate cooling. Before you install a cooling system for your home, be sure to consult a professional to get the right size. Both situations would lead to overworking your AC unit, resulting in increased energy bills.

7. Noisy AC Unit

Although it’s hard to have a completely quiet air conditioner, the noise should be bearable. If you experience this issue, be sure to check and clean your fans, vents, and ductwork.

Over time, your fans, vents, and ductwork accumulate dust, leading to a noisy AC system. Additionally, be sure to check for any loose parts and tighten them.
