Furnace Evaporator Coil Frozen

If the water is stuck in one place because of a clogged pipe it can freeze.

Furnace evaporator coil frozen.

A dirty air filter or restricted air movement in ducts could be preventing proper airflow. Frozen ac coils are caused by blocked condensate lines. While a frozen ac may be caused by malfunctions or damaged equipment proper maintenance can help avoid some issues. This will interfere with the creation of cool air for indoor comfort.

Condensate lines are the part of your hvac system that drains away excess moisture from humidity. In a properly functioning system the evaporator circulates refrigerant vapor at about 40 degrees the optimum temperature to extract heat from the airflow passing through the coil but never frigid enough to produce ice. If your evaporator coil has frozen up the first thing you should do is turn off your unit. Since they are no longer in contact with the surrounding air they will not be able to absorb that heat and air coming out of the supply vents will be warm.

Fixing a frozen evaporator coil a coating of ice on the evaporator coils will prevent the coils from working properly. This will cause the condensation on the coil to freeze over. One of the most common causes of a frozen evaporator coil is lack of system airflow. This is especially true if the obstruction happens near the evaporator coil the coldest part of the ac.

Over time your system s evaporator coil will become covered in dust dirt grime and more. Keep the evaporator coils clean as dirty coils can restrict air flow across them. When air isn t freely moving across the evaporator coil its temperature drops leading to a frozen ac coil. Air conditioners require correct refrigerant levels to operate.

How do i know if my evaporator coil is bad near okc. This prevents it from getting the airflow it needs to properly move heat which means that the system could then freeze over. If you continue to run the unit while the coil is frozen it could cause extensive damage to the system. Evaporator coil cleaning is an essential part of our ac tune up service for this exact reason.

If there isn t enough air blowing over your evaporator coil the coil won t have enough heat to absorb. Make sure to turn it off at the breaker box. This moisture condensed into water travels through pipes to a floor drain.
