The two sets of coils inside of your air conditioner have an important role to play in cooling the air down for your home. Even though they have a design to withstand long-term use, problems can still happen from time to time. If you suspect AC coil problems, give our team a call to schedule an appointment for HVAC repair in Rowlett, TX.
You can also keep reading to learn more about how AC coils work and the potential problems they face. We’re also highlighting ways to care for your AC and reduce the chances of coil problems as well as the signs to watch for so that if something does happen, you can get it fixed sooner rather than later.
Refrigerant Leaks
Your AC has evaporator coils inside and condenser coils outside. Refrigerant cycles through both sets of coils during each cooling cycle. Inside your home, the evaporator coils absorb heat from the air entering the system. By absorbing the heat, the temperature of the air lowers down enough that your air conditioner can blow out air that lowers your indoor air temperature.
Inside, the refrigerant expands as it collects heat. The outdoor coils release the collected heat and pressurize the refrigerant back down into a liquid. This cycle continues again all day long. But if the line gets damaged and refrigerant leaks out, there may not be enough of the chemical in the line for adequate cooling.
Refrigerant leaks make a hissing or bubbling sound depending on where the line gets damaged. If you hear hissing or bubbling, call right away for AC repair. Leaking refrigerant is dangerous and also makes your AC work less effectively.
Frozen Coils
Leaking refrigerant can contribute to frozen coils, but the larger issue is a lack of airflow coming into the system. If your air filter is very dirty or too strong for your AC, it blocks airflow from entering the system. Without any air to cool down, the coils get too cold. Moisture inside the system condenses down into droplets and freezes on the coils.
The issue repeats again and again until ice buildup is significant enough to block airflow even more. Fixing the problem means allowing ice to thaw out, cleaning it up, and then determining what caused the ice to begin with. If airflow is a problem, try changing your air filter or switching to a different type of filter that lets more air through.
Dirt Buildup
Even with a great air filter in place, some dirt does get into the system. Dirty coils may not work as well to absorb heat from the air. You can open the inside cabinet of your air conditioner and wipe the coils down with a dry cloth to eliminate dirt.
Doing this at least once per year is a good idea. Our team can complete this step during annual professional maintenance. If we find that your coils are particularly dirty, we may suggest that you wipe down the coils more often.
