The Evaporator coil works the opposite of the Condenser coil. An Evaporator coil job is to turn the liquid form of a chemical, such as Freon, to a gas while absorbing heat in the process. Essentially, it absorbs heat in the air and sends it back into your home as cold air. Unlike the condenser coil, an evaporator coil is located inside, near the air handler. It is made from different metals that conduct heat easily such as, cooper, steel or aluminum. Outside the coil are fins, which not only protect the coils, but allow the air to pass through them.
The following are two common issues that may cause a problem with your Evaporator coils.
If your refrigerant levels are running low your evaporator coils will not have enough refrigerant to absorb heat from your home’s air. This can cause your coil to ice up. Another issue that could cause your coil to freeze is low air flow. A clogged air filter, malfunctioning blower or a leak in your duct work are just a few examples of what could cause poor air flow.
Overtime your coil may also buildup with dust, dirt or other debris. This buildup can prevent your AC from functioning properly. Even a thin layer of dirt on you evaporator coil can make it more difficult to absorb heat. Again, this could cause your coil to freeze over.
One of the easiest ways to keep your evaporator coil functioning properly is to keep it clean. If your evaporator coil freezes over, trust Air Around the Clock to get to the root of the problem. Even better, check out all the benefits of our maintenance agreement and know how well your system is running before your coil has the chance to freeze.
