Air conditioning systems are a blessing during scorching summer months. They provide a haven of cool and comfortable air indoors. When your AC’s coils freeze up it can quickly turn into a frustrating situation with you suddenly needing to search for AC repair in Maumee, OH.
Frozen coils not only prevent the efficiency of your cooling system but also could mean that there is another underlying issue that needs attention. Let’s take a look at the reasons behind frozen AC coils and possible solutions to restore your cooling system to its optimal performance.
Understanding the Basics
Air conditioners work by transferring heat from inside your home to the outside. This heat exchange process involves the circulation of refrigerant through coils. The evaporator coils are located inside your home and the condenser coils outside. When these coils freeze it stops the heat exchange process and prevents your AC’s ability to cool properly.
Common Causes of Frozen Coils
- Lack of proper airflow over the evaporator coils is one of the main culprits behind frozen coils. This can result from dirty air filters, blocked vents, or closed registers. When the airflow is restricted the evaporator coils become too cold. This causes condensation to freeze on their surface.
- Refrigerant is the substance responsible for absorbing and releasing heat in the cooling cycle. If your AC is low on refrigerant due to leaks or inadequate levels, the evaporator coils can become too cold and freeze.
- A malfunctioning thermostat can cause your system to run continuously. This can lead to colder than normal coils. If allowed to go on for too long, the exposure to low temperatures can result in freezing.
- The blower fan is responsible for distributing cool air throughout your home. If the fan is not functioning properly it can reduce airflow over the evaporator coils.
- Over time dirt, dust, and debris can accumulate on the evaporator coils. This can insulate them and reduce heat exchange.
Solutions to Address Frozen Coils
- Regularly changing or cleaning air filters is important to maintaining proper airflow. Clogged filters restrict air movement and can lead to freezing coils. Check and replace filters every 1-3 months.
- Make sure that vents, registers, and the area around the indoor unit are free from obstructions that might block airflow.
- If you think the problem might be a refrigerant leak, you can contact a professional HVAC technician to inspect your system.
- Check and calibrate your thermostat to make sure the temperature is reading properly.
- Schedule regular maintenance with a professional HVAC technician to clean the evaporator and condenser coils.
- If the blower fan is malfunctioning, have it repaired or replaced.
Frozen AC coils are more than just a minor annoyance. They can signal underlying issues that require attention to keep your cooling system running efficiently. Regular maintenance, proper airflow, and professional inspections are important to prevent frozen coils and ensure your AC functions optimally during the hottest months!
