Your AC unit is one appliance in your home that can be easily overlooked – until it stops working. With summers in Louisiana often pushing triple-digit temperatures, your AC’s performance is in high demand for months at a time.
It may be hard to believe, but AC units can freeze up when the outside temperatures are roasting hot. What does a frozen AC really mean? Southern Air is here to help explain this common AC repair! Read on to learn more about what causes an AC unit to freeze and how you can avoid a midsummer AC repair.
First things first, if your AC is already frozen, there are two easy steps to take: thaw and dry. You want to make sure your AC repair is taken care of quickly so that normal function can return to the unit. If you feel comfortable, follow these steps to safely restore your frozen AC to working order.
If you don’t feel that you can complete these steps, a certified HVAC technician will be more than happy to help you out!
In a nutshell, frozen AC units are caused by poor airflow. When your system can’t pull in the right amount of air, the heating or cooling process can’t happen correctly. Since your unit deals with temperature changes and the reduction of moisture, poor airflow often causes the water in the air to stick to the coils, then freeze. Four common causes of poor airflow are:
Luckily, there are some things you can do to avoid this situation altogether! Let’s expand on the four main causes of poor airflow that can result in a frozen AC and find out how you can avoid them.
With regular use, evaporator coils attract grime and other debris from the air. With the addition of Louisiana’s high humidity, the coils can collect moisture on the tiny particles of debris and freeze. This results in damage to your AC system.
The best way to prevent a frozen AC as a result of having dirty coils is to schedule an AC tune-up. The technicians at Southern Air check your evaporator coils as part of routine preventative maintenance, lowering the risk of frozen coils.
A refrigerant leak is one of the leading causes of a frozen AC unit. Without adequate pressure from the refrigerant, your AC system reverses on itself – blowing warm air into your space instead of cool air.
Sometimes, your AC unit can be repaired and the refrigerant can be “recharged.” If your AC is older, however, a refrigerant leak is often caused for a replacement. It’s important to note that refrigerants should not be handled by uncertified people. It can be extremely dangerous when exposed to humans, and should be taken care of by a professional!
An AC system can only function if the air is allowed to circulate through it. A dirty or clogged air filter prevents airflow and is the number one cause of a frozen AC system.
Check your air filter monthly and change it as needed. For most households, air filters should be changed quarterly.
Similar to having a dirty filter, blocked return vents can cause airflow restrictions. Without adequate airflow, heat transfer cannot take place and your unit might freeze.
Other airflow issues can be caused by improper duct installation. Schedule air duct repair if you suspect your ductwork is damaged or is not the right size for your home.
