Why Your Air Conditioner Is Freezing Up
Have you noticed ice build up in your air conditioning unit? In extreme cases, you might even see a full block of ice. Before you panic, let’s walk through some of the causes as well as some simple solutions.
R22 refrigerant is essential to the function of your air conditioning unit. If there is a leak or any issues with your refrigerant levels, you will begin to notice that your home isn’t cooling as expected. Changes in refrigerant levels also impact the pressure within the system. When the R22 levels get low, the coils in your air conditioner become too cold. This can lead to a build up of ice on your unit. We recommend setting up annual maintenance with the Air Hawk team to ensure that your coils are properly maintained and your refrigerant doesn’t dip below the recommended levels.
As mentioned above, issues with the coils can lead to frost buildup on your air conditioning unit. Normally, during the dehumidifying process, condensation builds up on the coils and eventually falls into the drip pan. However, when the coils are dirty, they can’t absorb the water pulled from the air fast enough. As a result, the coils become waterlogged and the condensation freezes. The best way to avoid this scenario is once again scheduling annual maintenance.
Poor Air Circulation
A key factor in the function of your air conditioner is air flow. If there is poor air circulation, your home will be much warmer than expected—and there will also be issues around the coils in your AC unit. Poor air circulation prevents your system from getting the warm air it pulls from your home. This causes a buildup of water on the coils which will eventually turn to ice. To help with air circulation in your home, change your filters regularly and ensure that your vents aren’t obstructed.
