An air conditioner is a complex appliance and when it fails there could be a number of causes. The main symptom of a malfunctioning AC is loss of cool air, however, the things that can cause this problem range from a low refrigerant level to a fault in the compressor system. Even a diagnosis of a low refrigerant level may be due to various reasons. For example, refrigerant can be lost as the appliance ages or it could be the result of a break in the refrigerant lines. An expert in AC repair near Mundelein IL will need to examine the appliance to locate the fault.
The AC functions by causing a state change in a chemical refrigerant. This task is performed through compression. That is, the appliance will use a mechanical condenser to pressurize the refrigerant and the act of condensing the chemical causes it to change its characteristics. The reason that this is important is that one of the changes is the temperature of the refrigerant, and this lower temperature is what cools the metal of the evaporator coil.
Once the refrigerant is compressed, it passes through this coil and collects heat. The collection of heat also begins a change where the refrigerant reverts to its original form. This is the time when the appliance is working to cool the building because it is carrying the collected heat outdoors where it will be released through the condensing coil. This implies that AC repairs near Mundelein IL must be handled by an expert because improperly repairing these lines is an accident waiting to happen.
One thing to consider if the air conditioner is showing signs of age is that federal guidelines for chemical refrigerants have changed. Any system that was made before 2006 uses a refrigerant known as R-22. Modern appliances use the refrigerant R-410A, which must operate at a higher pressure. This means that older systems cannot be retrofitted to handle this chemical so they may need to be replaced when they fail. Factoring the cost of repair versus the cost of replacement is one reason to consider a seasoned contractor. An expensive repair for an older system may not be cost effective in the long run because a new appliance will function more efficiently.
