It is easy to assume that the AC freezing is a good thing since it is supposed to produce air. This isn’t always true because your AC has a refined process when it comes to functionality. There should be a balance between temperature, airflow, and pressure. You’re likely to experience issues if there is a problem with one of the items mentioned. It could mean searching for a heating and air Knoxville TN contractor to get to the bottom of the problem. Here are some of the steps that can help you determine the cause of your AC freezing up.
Reduction in Airflow
One of the most common reasons why your AC would freeze up is because of a lack of airflow. This could come about because of a couple of malfunctions with your unit. It could range from the air intake to a blown motor. A dirty air filter could also be the reason for reduced airflow. That’s why we recommend that you change your air filter at least every 45 days. You can start by checking the air filter if it hasn’t been replaced for a while. If it looks discolored or dirty in any way, it will be time to replace it.
Mechanical Issues With the Fan
The blower in your unit is responsible for moving the air over the coils. A faulty fan would mean that air is not moving sufficiently over the coils thus causing them to freeze. There could be a couple of reasons that could lead to a malfunctioned fan. It could be that the issue is electrical and is emanating from the capacitor. In other instances, the problem could be the fan itself or when there is a broken motor. It will be difficult to diagnose the exact problem when you’re not really sure of how the fan works. That’s why it is usually recommended that you reach out to an HVAC professional to do the job right.
Low Refrigerant
It will not be possible for the coils to absorb the heat when there is no refrigerant in your AC unit. The coils will most likely freeze up because there will be no air blowing over them. Since the refrigerant is a closed system, the issue is likely to be a leak from the inside. One of the signs of low refrigerant is poor cooling of your unit. You’re also likely to see an increase in energy bills. Since the repair is a two-part process, you will have no other option but reach out to an HVAC technician. The technician will first have to identify the source of the leak before coming up with a repair solution.
Repair Options
It is never a good idea to attempt to do HVAC repairs on your own. You should reach out to an experienced heating and air contractor instead so that your issue is fixed the first time. For more information on AC repairs, you can check out https://jcsheatingandair.com/
