The air conditioner in your home cools the air during a hot scorching day to make your house comfortable. It has core components, such as the evaporator coil, that transform the refrigerant into a gaseous state while absorbing heat from the house.

As the evaporator coil absorbs the heat, it leaves your home in Garland, TX, with sufficient cold air passing through the air ducts and supply vents. So, if the evaporator coil malfunctions, it implies that the entire air conditioning unit will not function at its peak performance, hence the need for an air conditioning service provider to fix it.

Just like other components of the cooling system, the evaporator coils are also prone to technical problems from time to time. It can freeze due to various aspects such as dirt, clogged drain line, and blocked air ducts. Below are some of the signs of a frozen evaporator.

AC Malfunctioning

When the AC stops producing cold air necessary for cooling your home it is a sign that the evaporator coil is frozen. It can freeze due to dirt that accumulates on it over time. The debris and dust build-ups, blocking the airflow and insulating the coils, which compromises the ability of the evaporator coils to absorb heat and produce cold air.

The summed-up debris makes the coils unable to move the heat from your house, thus freezing because they continue to receive cool air. To unfreeze the evaporator coils, the air conditioning service expert will clean the air filters and the coils to clear up the clog.

Fortunately, regular maintenance services are available in most heating and air companies that help prevent the possibility of dirt blocking the airways and freezing.

The air conditioning professionals can also offer you routine tune-up programs that will guarantee cleaning of the AC system, including the evaporator coils.

Ice on the Outside Refrigerant Line

The other sign of frozen evaporator coils is ice on the outside unit of the refrigerant line. The lines are two copper wires that the air conditioning technician connects to the evaporator coils for peak performance. The evaporator coils possess a refrigerant responsible for removing heat from the air in your house in Garland, TX, and pushing cold air back in the rooms, leaving them comfortable when the temperatures are unbearably high.

If they are covered with ice, it implies that the evaporator coils are already frozen solid, and any additional refrigerant becomes excessive, hence flows outside. It is also an indication that there is no warm air flowing in the coils, making them unable to exchange heat and cold air.

Hiring an air conditioning service contractor is appropriate in identifying the actual reason as to why the evaporator coils are not receiving warm air, which could range from dirty air filters to blocked air vents.

Evaporator Coils Covered with Ice

Another sign of frozen evaporator coils is ice covering the coils. The evaporator coils are prone to freeze when the refrigerant that makes them function smoothly is low.

When the refrigerant leaks, it reduces to a low level that makes it impossible for the coils and the AC to operate at optimal efficiency and distribute cold air in your house. The decreased refrigerant liquid causes the pressure in the AC to drop, making the evaporator coils extremely cold and covered with ice.

An experienced air conditioning service professional will identify the parts leaking the refrigerant for the appropriate repairs before adding more non-ozone depleting refrigerant that will make the evaporator coils work at their peak.

However, if the air conditioning technician finds additional issues such as broken or damaged coils, replacing the evaporator coils alone might not be a solution because of the probability of a mismatch with the condenser.

The mismatch will make the AC consume a lot of energy to produce cold air in your home. Therefore, replacing the entire AC system might be appropriate, especially if it is more than 10 years old.

Clogged Condensate Drain Lines

Additionally, clogged AC drain lines signify that the evaporator coils are frozen and need the urgent attention of air conditioning service providers. Drain lines are responsible for removing excess condensation in the AC unit. If they fail to operate smoothly, they will retain the moisture inside the air conditioner, leading to frozen evaporator coils.

When the evaporator freezes due to clogged drain lines, the extra water in the condensate lines will also freeze, making the whole AC unit malfunction. Fortunately, a licensed and experienced air conditioning service contractor can skillfully unclog the drain lines and restore the AC to optimum functioning.

Overflowing Condensate Drain Pans

Another sign of frozen evaporator coils is the overflowing drain pans. The low refrigerant causes the evaporator coils to be filled with ice creating more water that exceeds the drain system to drain it freely, causing the drain pan to overflow.

The drain pan overflowing might also be due to blocked drain lines. When this happens, it’s advisable to call an experienced air conditioning service expert to unclog the drains to prevent water from overflowing.

The technician might recommend regular maintenance and tune-ups for the evaporator, condenser, and other components of the AC system to avert any problems that might compromise the sufficient provision of cold air or indoor air quality.

Failure to contact an air conditioning service provider on time might cause mold growth and rot of wooden structures close to the AC condensing unit.
