Dirty filters block airflow and cause unit to freeze

Dirty air filters can cause your air conditioning unit to freeze, which can be frustrating and uncomfortable. This happens because when your air filters become clogged with dust and debris, it blocks airflow, causing the evaporator coil to become too cold. When this coil gets too cold, the humidity in the air can freeze around it, causing your unit to freeze up.

To prevent this from happening, it’s essential to check and clean or replace your air filters regularly. Clear air filters mean unobstructed airflow, which keeps your air conditioning unit functioning correctly and efficiently. Neglecting to change your air filters can also cause your unit to work harder, leading to increased energy bills and possible damage to the unit’s components.

So, keep your air filters clean and enjoy a comfortable home all year round.

If your mini split AC is not blowing cold air, the first thing you should do is take a quick look at the outdoor unit. This part of the system plays a crucial role in cooling your home, and any issues with it can cause your mini split AC to malfunction. Check to see if there is any debris or obstruction around the unit that could be blocking proper airflow.

If so, remove the debris and give the unit a thorough cleaning. You may also want to inspect the refrigerant lines to see if there are any leaks or damage that could be causing the problem. If you notice anything out of the ordinary, it’s best to call a professional to take a closer look.

By properly maintaining your mini split AC’s outdoor unit, you can help ensure that it cools your home effectively and efficiently.

Clear any debris in or around unit

Inspecting the outdoor unit of your air conditioning system can significantly enhance its performance and lifespan. One of the most important steps in outdoor unit inspection is clearing away any debris that could hinder its proper functioning. Debris accumulation on and around the unit can restrict airflow, obstruct critical components such as the condenser coils, and impact refrigerant circulation, leading to premature wear and tear.

As a result, before starting the unit up for the summer, it’s crucial to examine the outdoor unit, remove any dirt, twigs, leaves, or other foreign objects that may be clogging the condenser coils, and tidy up the surrounding area. Additionally, trimming any vegetation that may be growing too close to the unit is advisable as it allows sufficient space for air to flow freely in and out of the system. By taking care of your outdoor unit, you can minimize wear and tear, reduce energy usage, and extend the lifespan of your air conditioning system.
