5 Signs That Your Evaporator Coil Needs an Immediate Replacement
One of the most important components of your air conditioner is the evaporator coil. Without this part, your AC unit is unable to convert the refrigerant back and forth between a gas and liquid, which makes it impossible for the AC to absorb heat from the air and cool down your home. There are some situations when an AC repair service in Atlanta can repair the coil, but in other cases, the coil should be replaced altogether. Here are some signs that may indicate the need for coil replacement.
While you may not think about how your AC unit works to cool your home, it's important to understand that your AC works by removing humidity from your air. That means that if you notice the air from the registers being warm or you notice that your home feels more humid than usual, it's often a sign that the evaporator coil is damaged, sometimes from corrosion. It could also be due to frost on the coil, the cause of which could also be a bad evaporator coil and which requires the inspection of an HVAC professional.
If your AC system is unable to function properly due to a problem with the evaporator coil, you may notice strange sounds when the system is running. These sounds may come from the indoor air handler unit or the outside condenser unit and may include hissing, banging, or clanking sounds.
If your AC is cycling more frequently, which means it turns off and on often, it probably means that there's frost buildup on the evaporator coils. When the coils have frost on them they're unable to work properly, so the cycles are shorter than they should be. This can cause additional stress on your AC and raise your energy bills. If you have an older AC unit, often the best solution to this is to replace the coil rather than replacing it.
The evaporator coil is located inside your home, so it's important to watch for any leaking around the indoor unit. It's normal to have condensation from the cooling process. Normal condensation is taken care of through the condensate line and drip pan. However, if you notice excess water leaking, it's possibly due to a flooded condensate line caused by frost build up on the coil.
AC Not Running
Any time your AC won't run, you should call professionals for air conditioning installation in Atlanta. This could indicate a few different problems, but many times, the problem is due to an evaporator coil issue. If the problem is due to the evaporator coil, you should consider having it replaced if your AC is older than 7 years, if the repair cost is more than 1/3 or 1/2 replacement costs, or if the SEER rating is 12 or lower.
