When the summer heat hits, we rely on our air conditioning unit to provide us with cool air. However, when the AC coils keep freezing, it can lead to a whole new set of problems. If you’re wondering what causes frozen AC coils and how to fix them, you’re in the right place.
Below, we’ll explore the primary reasons your air conditioner coils freeze and discuss some tips on how to solve these issues.
1. Dirty Air Filters
One of the most common reasons AC coils keep freezing is that the air filters are dirty. Dirty air filters restrict the flow of air, leading to low air flowing over the evaporator coil. Without adequate airflow, the coil becomes too cold, and eventually, ice forms.
To prevent this from happening, make sure you change your air filters regularly. Experts recommend changing the air filters every 30 to 90 days, depending on usage.
2. Low Refrigerant Levels
Low refrigerant levels can also be what causes frozen AC coils. The refrigerant is responsible for absorbing the heat from your home and releasing it outside. However, if there isn’t enough refrigerant, the AC system won’t be able to absorb the heat.
When the refrigerant levels are low, the evaporator coil will become too cold, and ice will form. To fix this issue, you must contact an HVAC technician who can recharge your refrigerant levels. If the coolant levels are low, it may be due to refrigerant leaks. When there’s a refrigerant leak, the system cannot perform efficiently, and the evaporator coil will start freezing.
A qualified HVAC technician should inspect your air conditioning system for any refrigerant leaks. They will then fix the leak and recharge the refrigerant lines. So, if you think you’re experiencing this issue, don’t hesitate to call us and schedule your air conditioner repair in Saint Cloud, MS.
3. Dirty Evaporator Coil
During operation, dust, dirt, and other debris can collect on the evaporator coil. As this debris builds up, the coil becomes insulated and can’t absorb heat. This causes the refrigerant to remain too cold, making the coil freeze.
If you want to fix this issue or prevent it from happening, it’s crucial to keep the condensate drain clean. If you notice water dripping or pooling around your air conditioning unit, contact an HVAC technician who can remove any blockages from the condensate drain.
4. Blower Fan Issues
When discussing what causes frozen AC coils, we have to mention how detrimental a malfunctioning blower fan can be. A blower fan is responsible for pushing air over the evaporator coil. If the fan isn’t working correctly, it will cause low airflow, which could be why your AC coils keep freezing.
Homeowners can clean the evaporator coil by vacuuming or brushing it gently. If you’re not comfortable doing this yourself, it’s best to call an HVAC technician for professional cleaning.
5. Condensate Drain Blockage
Your air conditioning unit has a condensate drain that removes the moisture from the air inside your home. However, if the drain becomes clogged, the water can’t flow freely, which results in an overflow of water in your system. This, in turn, causes the evaporator coil to freeze.
If you want to fix this issue or prevent it from happening, it’s crucial to keep the condensate drain clean. If you notice water dripping or pooling around your air conditioning unit, contact an HVAC technician who can remove any blockages from the condensate drain.
