As the scorching summer heat rolls in, having a functioning air conditioner is crucial to beat the heat and stay comfortable indoors. However, a common issue homeowners encounter is their air conditioners freezing up unexpectedly. This phenomenon compromises the cooling efficiency and can lead to potential damage if left unaddressed. In this blog post, we will explore the reasons behind air conditioner freezing and provide effective solutions to fix the problem. If you're experiencing AC troubles in Niagara Falls, Ontario, contact Niagara Home Heating for reliable AC repair services.

Understanding the Causes

Inadequate Airflow: One of the primary reasons for AC freezing is restricted airflow. This can occur due to dirty air filters, blocked vents, or closed registers. When airflow is restricted, the evaporator coil can become too cold, causing condensation to freeze on its surface.

Low Refrigerant Levels: Refrigerant plays a crucial role in the cooling process of your air conditioner. If there's a refrigerant leak or insufficient levels, the evaporator coil can become excessively cold and freeze over time.

Faulty Thermostat: A malfunctioning thermostat can lead to erratic temperature control, causing your air conditioner unit to run continuously. This prolonged operation can result in the evaporator coil becoming too cold and eventually freezing.

Dirty Evaporator Coil: Over time, dust and debris can accumulate on the evaporator coil, hindering its heat exchange capabilities. This buildup can cause the coil to become excessively cold and freeze up.

Fixing a Frozen Air Conditioner

  1. Check and Change Air Filters: Regularly inspect your air filters and replace them every 1-3 months, depending on usage. Clean air filters promote proper airflow and prevent the evaporator coil from freezing.
  2. Ensure Proper Airflow: Ensure all vents and registers are open and unobstructed. Keep furniture, curtains, or other objects away from blocking the airflow. Ensure that nothing is obstructing the outdoor unit's airflow as well.
  3. Verify Refrigerant Levels: If you suspect a refrigerant leak or low levels, it's essential to contact a professional HVAC technician to inspect and recharge the system as needed. Attempting to handle refrigerant yourself can be dangerous and may require a license.
  4. Calibrate or Replace the Thermostat: If your thermostat is malfunctioning, it's best to calibrate or replace it with a qualified technician. A properly functioning thermostat ensures accurate temperature control and prevents unnecessary strain on your air conditioning system. Maintaining a comfortable indoor environment during scorching Canada summers is essential for your well-being. Don't wait to address the issue if your air conditioner is freezing up or showing signs of distress.

I called John today at 2:pm as my AC was not working and I wasn’t expecting even a call back as I knew with this hot weather we have had he would be swamped with calls. Well he called me back and  showed at 8:pm on the same day  to fix my AC. That is just incredible service and how much John really cares about his clients. Thank you John !

Very efficient company. I needed an old solar water heater removed from my roof. They were quick to book an appointment for the next day after I sent photos. They were very knowledgeable of the issue. The 2 guys that came were friendly and competent with the job, including removal of all parts.

Lifesavers!! The AC in our house decided to quit the day we were passing the keys to the new owners!! Instead of making a service call to the house, John coached me through the minor repair over the phone, saving me the money and time waiting for a repair person to come.
Much appreciated! Thanks again John
