An evaporator coil is an essential component of an air conditioning unit that helps cool your home in Arlington, TX, increasing indoor comfort when the outside is scorching hot as a sauna. It is a web of A-shaped copper coils found inside your air handler. The evaporator coil is crucial in an air conditioner because it makes the entire system operate efficiently in providing cool air in your rooms by sucking all the heat indoors.
The coils have a refrigerant fluid that carries the sucked heat to the condensing unit placed outside your home. When the evaporator coil is faulty, it compromises the proper functioning and efficiency of the whole air conditioner. You should be ready to contact your air conditioning repair expert once you realize the air coming from your AC is warm instead of cool, you cannot switch your AC on, and unusual noises to check and inspect and fix the coils. Here are some of the evaporator coil problems you are likely to encounter.
Frozen Evaporator Coils
One of the problems you might face in your evaporator coils inside the air handling unit is freezing. The evaporator coils can freeze because they have malfunctioned and are not absorbing warm air from your rooms. Without the heat that it sucks from the house, the evaporator coils will remain with the cold refrigerant forming a film of ice. The cause for the frozen evaporator coils is impeded airflow to the evaporator coils, which compromises the heat exchange process making your home in Arlington, TX, warm and the evaporator coils cool. An air conditioning repair contractor can identify the reason behind the impeded air into the evaporator coils and fix it. Another reason for the frozen evaporator coils is the leaking of refrigerant.
A refrigerant is a liquid inside the evaporator coil that transfers heat absorbed from inside the rooms to the external condensing unit. The refrigerant in the evaporator coils sucks warm air blowing over the evaporator coils leaving cold air to cool your space and home. Without the liquid in the evaporator coils, your AC will not efficiently condition the air to the required low temperatures. Once the AC produces warm air increasing the temperature-related discomfort, you should contact an air conditioning technician to check and diagnose the actual reason behind the warm air.
As a specialist in AC units, it should not take the contractor much time to identify the low refrigerant level. The coolant can only reduce if it is leaking, affecting the way it operates. With the inadequate refrigerant in the evaporator tubes, your AC will consume a lot of energy to cool your rooms, thus increasing your utility bills. The high energy costs will compel you to get an air conditioning repair professional to fix the problem immediately.
As the air conditioner overworks, it increases its probability of a sudden breakdown, which will need repair services. You will know the coolant in the evaporator coils is seeping out when your energy bills increase, the AC struggles to cool your space, and when the evaporator coils are frozen. The signs are enough for you to hire a highly regarded air conditioning company to fix the problem.
i) Causes of the Refrigerant Leaks
One of the reasons why your refrigerant is leaking is because the evaporator coils are corroding. The evaporator coils are prone to rust when exposed to acidic chemicals. If you use acidic products and cleaners in your home, you are more likely to have a corroded evaporator coil. The reason being the warm air blowing through the evaporator coils will have acids that will lead to the corrosion of coils. An air conditioning repair expert can replace the corroded copper evaporator coils to restore the AC to its original working condition. Another reason for the leakage might be age-related. If your Ac is old, it will have wear and tear that might cause a crack in the coils leading to leaking of the refrigerant. Your air conditioning repair specialist will notice the problem during tune-ups and replace all the worn-out evaporator coils. When your air handler is close to heavy vibrating machinery, it might cause significant damage to the evaporator coils, making the refrigerant leak.
ii) Dangers of the Coolant
People should not inhale the refrigerant because of its poisonous chemicals that can deplete the ozone layer. When it leaks in your AC, it exposes you and your family to health issues related to respiratory tract infections and skin irritations. Enrolling in a maintenance program with a reputable air conditioning repair company to regularly check and tune up the evaporator coils might prevent leaking coolant.
Dirty Evaporator Coils
Dirt causes a lot of operational issues in most appliances especially, the air conditioner. Dirty evaporator coils will fail to absorb heat from your rooms. The summed-up dirt will impede the cooling features of the evaporator coils and the coolant leading to a sudden breakdown of the entire AC unit. Your AC appliance might also fail to provide the much-needed cool air and increase your utility bills. Removing the debris accumulated from the coils should be done by trained air conditioning repair technicians. They can also clean the entire AC system during routine maintenance and tune-up processes, reducing the possibilities of sudden malfunctioning.
Improper-sized Evaporator Coils
If an inexperienced air conditioning repair technician replaces the damaged evaporator coils in your AC with smaller or large ones, they will not operate smoothly. The evaporator coils in your indoor AC unit must match with the condenser coils for peak performance of the entire AC system. Therefore, you should change to a skilled and intensively trained air conditioning expert to get the correctly sized evaporator coils and fix the issue.
