A properly functioning air conditioning system is essential to maintain a comfortable living environment during the hot summer months. However, a common problem many homeowners face is a frozen AC unit, which can cause significant damage to your AC system and increase energy bills. In this article, we’ve outlined three common reasons why your AC might be freezing up and what you can do to prevent this from happening.
Reasons Why Your AC Might Be Freezing Up
A frozen AC unit can be caused by a variety of factors, but there are three common reasons why your AC might be freezing up. In this blog post, we’ll discuss those three reasons and what you can do about them.
Dirty Air Filters
Dirty air filters are one of the leading causes of a frozen AC unit. The air filter in your AC system is responsible for trapping dust, dirt, and other debris that may circulate in the air. Your system’s airflow may be decreased if the air filter gets clogged over time. When there is not enough airflow, the evaporator coil can get too cold, causing it to freeze. To prevent your AC system to freeze up, it’s essential to schedule regular AC repair in Naperville, IL.
The air in your home is cooled after being absorbed by the evaporator coil, which is also in charge of absorbing heat from the air. When the evaporator coil freezes, it can cause significant damage to your AC system. It can also lead to increased energy bills, as your system will have to work harder to maintain a comfortable temperature.
To prevent dirty air filters from causing your AC system to freeze up, it’s essential to replace your air filter regularly. Depending on usage, the majority of manufacturers advise changing the air filter every one to three months. You can guarantee optimal airflow and avoid your AC system freezing up by replacing your air filter on a regular basis.
Low Refrigerant Levels
Refrigerant is a chemical substance that absorbs heat from the air and transfers it outside, allowing your AC system to cool your home. When the refrigerant levels are low, the evaporator coil can get too cold, causing it to freeze up. Your AC system’s leaks may be the source of low refrigerant levels.
These leaks can be challenging to detect and repair and require the assistance of an experienced AC technician. Low refrigerant levels can also be caused by poor installation or incorrect sizing of your AC system. If your AC system is too small for your home, it will have to work harder to cool your home, causing the refrigerant levels to deplete faster. This can lead to a frozen AC unit and increased energy bills.
If you suspect that your AC system has low refrigerant levels, it’s essential to contact our experienced HVAC repair Naperville, IL to diagnose and repair the issue. They will perform a refrigerant leak detection test and refill your system with the appropriate amount of refrigerant to prevent your AC unit from freezing up.
Dirty Evaporator Coil
A dirty evaporator coil can also cause your AC unit to freeze up. Over time, the evaporator coil can accumulate dust and debris, reducing its ability to absorb heat from the air. When the evaporator coil can’t absorb enough heat, it can get too cold, causing it to freeze.
A dirty evaporator coil can also lead to poor indoor air quality. The dust and debris on the evaporator coil can circulate in your home, leading to respiratory problems and allergies. It can also cause your AC system to work harder, increasing your energy bills.
During the maintenance, An experienced AC technician will clean and maintain your AC system, including the evaporator coil. Regular maintenance and repair will ensure that your AC system is functioning properly and prevent any potential problems.
A frozen AC unit is a frustrating and potentially expensive problem. However, by understanding the three common reasons why your AC might be freezing up, you can take the appropriate action to prevent this from happening. Regular AC maintenance, including replacing your air filter regularly, checking refrigerant levels, and cleaning your evaporator coil, will ensure that your AC system is functioning properly and prevent it from freezing up.
