Frozen Coils in Summer: How is that Possible?
Is your A/C starting to freeze up this summertime? This can be caused by an ice buildup in your coils. Let’s take a closer look at how this is possible in the midst of a heat wave.

Evaporator and condenser coils—these two are responsible for the heat transfer and cooling process of your unit. When ice buildup starts to cover them, it’s a sign of trouble in your system.

Let’s find out what’s causing them to ice up.

  • Damaged Blower Fan

The blower fan is responsible for sucking the heat and bringing cool air in your home. When it gets damaged, the airflow significantly changes, and condensation starts to build up in your coils. Immediate attention is required to avoid further costs in your system.

  • Clogged Air Filters

Clogged air filters are another reason for frozen coils. How? Dirt, mold, and other airborne pollutants can obstruct the air in your air conditioner. If the air is stuck around the coils, it will start to freeze up and cause your system to breakdown. So, check your air filters regularly and replace it periodically.

  • Faulty Thermostat

The thermostat can make or break your system. If your thermostat is not working properly, your A/C will work harder or runs too cold. Ice can also build up in your coils. If you’re still using the old manual-dial type, consider recalibrating or switching to a programmable thermostat.

  • Dirty Condenser

Your outside unit is called the condenser, which is often left unchecked and uncleaned. Dirt, mold, and other debris negatively affect the cooling process of your system, causing ice buildup in your coils too. These extra loads are causing your A/C to overheat and reduce its lifespan.  Make sure to check and clean your condenser regularly. Use soft brush and gently remove these filthy particles or use water to wash it off.

  • Refrigerant Issues

Refrigerant is a chemical involved in cooling your home, and having issues with it can harm your health. The low refrigerant level is another reason for frozen coils. Refrigerant leaks can damage your system, leading to costly repairs. Do not ignore this red flag and contact the pros to get it checked and fixed immediately.
