How To Address An Overheating AC Unit

If you have a central AC system that is constantly overheating, then you likely are not getting the cooling power that you desire. In this case, you need to search out some solutions to the issue so you can get the cool air that you pay for. 

Consider The Sun

The outdoor AC condenser is responsible for releasing all of the heat that was absorbed by the indoor AC evaporator. This heat is released from the fins along the sides of the unit so the refrigerant is ready and able to cool your home again. Unfortunately, the unit may not be releasing as much heat as it should be if the condenser is placed in a sunny area. This can lead to overheating issues.

You can cut down on sun exposure by installing something that will block the sun's rays. A lattice enclosure is one option and so is a short fence or a canopy that sits high above the condenser.

Keep in mind that when you are looking for a construction to reduce heat and direct sunlight, you will still need to provide plenty of airflow. So, install the enclosure a few feet away from the AC unit on all sides. And, since the fan sits on the top of the device, you want a canopy to sit four to five feet above the top of the unit.

Keep in mind that thoughtful landscaping can also help to keep your AC unit as cool as possible. Just make sure that bushes and trees are secured far enough away from the condenser unit that debris will not clog the device.

Investigate The Unit

If you notice your AC unit running and then turning off after minimal usage, then this is a sign that the device is overheating. One of the most common causes of this is a unit that does not have enough coolant. When coolant leaks from the unit, the device is unable to cool the air or release heat effectively. This results in overheating and very little output from the device.

A unit that runs on inadequate levels of refrigerant can easily become damaged, and this is a concern when it comes to the unit's pump. If you suspect that your unit has a coolant leak, stop using your air conditioning until an air conditioning repair technician can assess the situation. The professional will use a device that measures the pressure of the coolant in the coolant lines. And, if there is not enough coolant, the device will be investigated for a leak and new refrigerant will be added.
