Furnace Evaporator Coil Frozen

Condensate lines are the part of your hvac system that drains away excess moisture from humidity.

Furnace evaporator coil frozen.

Keep the evaporator coils clean as dirty coils can restrict air flow across them. One of the most common causes of a frozen evaporator coil is lack of system airflow. Evaporator coil cleaning is an essential part of our ac tune up service for this exact reason. How do i know if my evaporator coil is bad near okc.

This is especially true if the obstruction happens near the evaporator coil the coldest part of the ac. A dirty air filter or restricted air movement in ducts could be preventing proper airflow. Make sure to turn it off at the breaker box. This will interfere with the creation of cool air for indoor comfort.

Over time your system s evaporator coil will become covered in dust dirt grime and more. While a frozen ac may be caused by malfunctions or damaged equipment proper maintenance can help avoid some issues. When air isn t freely moving across the evaporator coil its temperature drops leading to a frozen ac coil. This can be due to anything from closed off air registers to a malfunctioning air handler.

If there isn t enough air blowing over your evaporator coil the coil won t have enough heat to absorb. Replace your system s air filters regularly. If your evaporator coil has frozen up the first thing you should do is turn off your unit. The first concept to understand while troubleshooting a frozen evaporator coil is that the coil is supposed to be cold but not freezing.

If the water is stuck in one place because of a clogged pipe it can freeze. This will cause the condensation on the coil to freeze over. If you continue to run the unit while the coil is frozen it could cause extensive damage to the system. This moisture condensed into water travels through pipes to a floor drain.

Air conditioners require correct refrigerant levels to operate. This prevents it from getting the airflow it needs to properly move heat which means that the system could then freeze over. Frozen ac coils are caused by blocked condensate lines.
