Are Frozen Coils a Problem for Your AC?

When you hear the phrase frozen coils, you may think that your air conditioner is extra cold. But that’s not the case. Instead, your air conditioner may be warmer than usual thanks to ice blocking refrigerant lines. 

You can keep reading to learn more about some of the signs that can indicate you have frozen coils on your air conditioner or heat pump. If you notice any of these signs or suspect frozen coils, give our team a call to schedule air conditioning repair in Ontario.

Signs of Frozen Coils

You may have frozen coils if you notice that lukewarm air is coming out of your air vents instead of cool air. Your indoor air temperature may also be higher than you expect. It’s possible that the temperature on your thermostat doesn’t match the actual temperature of your home. You can try measuring the temperature with a separate thermometer to compare the two temperatures and see how close or far apart they are. 

When coils freeze, some of that ice can melt and lead to leaks. If you notice pools of water under or around the indoor portion of your AC unit, ice on the evaporator coils may be to blame. You can usually open the cabinet for your indoor AC and see if there is in fact ice on the coils. 

If there is, you need to turn your AC off completely to allow the ice to thaw out. Be sure to place some towels around the unit to absorb the leak and reduce as much water damage as possible. Then give our team a call to schedule a service appointment so that we can assess whatever the contributing problem is and get your AC working as usual again.

Why Coils Freeze

Coils usually freeze due to a lack of airflow. Sometimes a refrigerant leak can contribute by blocking air flow from reaching the coils. You may also have poor airflow thanks to a clogged air filter. If you check your air filter and it is particularly dirty, that’s probably the reason your coils developed ice. Without enough airflow to cool down by absorbing heat, your coils freeze instead.

Preventing Frozen Coils

It’s easy to prevent frozen coils simply by changing out your air filter on time. You can note how long your air filter is estimated to last and set reminders so you know exactly when to change it out. If your air filter gets particularly dirty, you may want to set a reminder for a little bit earlier than it is actually due to be changed out.

You can also pay attention to signs that your AC is not operating correctly. This includes listening for bubbling and hissing sounds that can indicate a refrigerant leak. You can also hold your hand up to an air vent periodically to make sure that the airflow feels specifically cool.
