Here\u2019s a question we often hear from homeowners who want to be sure they\u2019re air conditioning systems work at their best: \u201cWhen will I need to have the refrigerant in the AC topped off?\u201d<\/p>\n
The answer is: \u201cHopefully, never.\u201d If an air conditioning system doesn\u2019t suffer from problems with refrigerant leaks, it won\u2019t ever<\/em> need to have any additional refrigerant put into it. Adding refrigerant isn\u2019t a maintenance task, but a repair issue. We\u2019ll go into more details below.<\/p>\n The reason people often make the assumption that refrigerant has to be topped off or refilled on a regular basis is because they\u2019re mistaking refrigerant for fuel. Refrigerant isn\u2019t like the gasoline in a car, however. It\u2019s more like the oil, although even that\u2019s not fully accurate since oil degrades and needs to be changed regularly.<\/p>\n Refrigerant\u2019s job in an AC is as a heat transfer medium. The air conditioner doesn\u2019t use the refrigerant for power. It uses its actual power source\u2014electricity\u2014to place refrigerant under pressure so it will circulate through the system. The refrigerant moves through a process of evaporating and condensing: it evaporates in the indoor coil to draw heat out of the air and condenses in the outdoor coil to release the air. As the refrigerant switches between liquid and gaseous states, it doesn\u2019t dissipate or get \u201cused up.\u201d An air conditioner should run on the same amount of refrigerant, known as the AC\u2019s charge<\/em>, for its entire service life.<\/p>\n Unfortunately, an air conditioning system can lose refrigerant because of leaks along the copper lines. This is the only way that an AC can see a drop in its refrigerant charge. When this happens, HVAC technicians must do two things: 1) stop the refrigerant loss by sealing the leaks, and 2) recharge the refrigerant to its factory level.<\/p>\n A loss of refrigerant is a serious problem. It not only means a drop in the air conditioner\u2019s cooling power since it can\u2019t move as much heat outdoors. It will also cause catastrophic damage to the compressor, leading to a complete system breakdown. If you notice your AC is not performing as well as it should, or you notice other warning signs such as a hissing sound from the system or ice appearing along the evaporator coil, call for repair technicians right away. It\u2019s crucial to have experienced professionals on the job to locate the leaks as well as ensure that the correct amount of refrigerant is recharged. (Too much refrigerant in an AC can create as many problems as too little.)<\/p>\n If you have an AC installed earlier than 2010, it may use a refrigerant blend known as R-22 (aka \u201cFreon,\u201d although this is actually a brand name). R-22 is being phased out and will no longer be available for repairs in 2020. We recommend upgrading to a new system that uses R-410A as soon as you can.<\/p>\n When you notice a decline in cooling in your home and suspect you need AC repair in Warsaw, IN<\/a>, never hesitate to get in touch with us.
