Troubleshooting a freezing air conditioner


You want your air conditioner to produce cool air in your home. However, you don't want the unit itself to freeze! Sometimes ice can form on the air conditioner, and there are several reasons why this can happen.


Here are some common problems that can cause your AC to freeze and how Fagnan's Furnace Service can fix them!


Insufficient airflow


A primary culprit behind a freezing air conditioner is restricted airflow. If the air filter is clogged, it can block airflow and reduce heat exchange. As a result, the condensation on the evaporator coil may freeze, causing issues with the cooling process.


Low refrigerant


Refrigerant is the lifeblood of an air conditioning system. Insufficient refrigerant levels due to leaks or improper installation can cause the evaporator coil to drop below freezing point. If this happens, it can cause ice to form.


Dirty evaporator coil


Over time, the evaporator coil can accumulate dirt and debris. As a result, that dirt can obstruct proper heat exchange. This buildup prevents the coil from absorbing enough heat, resulting in a freezing coil.


How to prevent or fix an AC freeze up


Regular air conditioner service

Schedule routine maintenance with Fagnan's Furnace Service to ensure your air conditioner is in optimal condition. An AC maintenance service can include cleaning the evaporator coil, checking refrigerant levels, and replacing air filters.


Ensure the air is flowing

Regularly inspect and clean or replace air filters to ensure proper airflow. Keep the area around the outdoor unit clear of debris, plants, and shrubs too.


Fix any leaks

If you suspect a refrigerant leak, contact a qualified HVAC technician. We will identify and repair the leak and recharge the refrigerant to the appropriate level. It can be an easy fix that will prevent more issues in the future.


Don't ignore that ice!

Ignoring a freezing air conditioner can lead to more significant problems. The strain on the compressor and other components can result in costly repairs or even premature failure. Additionally, a strained air conditioner has to work harder to cool your home causing higher energy bills.
