Freon leaks can go undetected for a period of time, costing you larger expenses as time goes on.
Has your air conditioner been leaking freon? Freon leaks normally begin as small leaks that may go unnoticed for as long as a year before you realize that the air conditioner is not efficiently cooling your home. What are some indicators your air conditioner is leaking freon?
Low Freon Level
In HVAC systems, it is necessary to ensure that the air conditioner is full of freon to allow it to function properly. If there are indications that the air conditioner is not full of freon, it means that freon is already leaking.
Pipes Have Ice on Them
The pipes located outside the house or on the evaporator coil normally have ice on them when the air conditioner does not produce cold air. This is a good indicator of a freon leak. However, icy pipes can also be caused by blocked air returns and vents.
Air Conditioner Is Not Producing Cold Air
The cooling power of an air conditioning unit will decline when it has a freon leak. Take note of any increases in your electricity bills or the amount of time the air conditioner takes to achieve the thermostat settings.
HVAC technicians have a trained eye that allows them to immediately notice any freon leaks. Freon is combined with oil in R22 systems and any leak will produce stains or greasy spots due to the oil.
Aside from improper installation, there are some times when manufacturing defect is the cause of a freon leak. It may be possible that a weld was not done properly during the production process or the air conditioning unit suffered a puncture while it was packed or delivered by the company.
Formic acid is an acid that forms naturally and is taken out of the ground. It can scratch the copper coil and result in minute fractures on the copper itself. As the leak becomes worse, it may require additional freon after a period of time.
Since the pipes of the air conditioning unit are located along the walls and other structures inside the house, a line may become punctured when a picture nail is hammered into the wall.
