Evaporator coils are an essential part of your home’s cooling system. They work to remove heat and moisture from the air in your home. This process helps to keep you comfortable all summer long. As long as your coils are working properly, your home will remain at your desired temperature.
A frozen evaporator coil is one of the most common problems that can occur with a home’s air conditioning system. Nothing is more frustrating than having your air conditioner coil freeze up just as the temperature outside is climbing. Coils freeze when the temperature in your evaporator coil drops too low. This problem can be caused by a variety of factors, including a dirty filter, low refrigerant levels, or dirty coils. If the evaporator coil becomes frozen, the air conditioning system will not be able to produce cold air. There are several things you can do to prevent your coils from freezing over. Keep reading to learn how to prevent frozen evaporator coils.
Clean your evaporator coils regularly.
One of the first things you can do to prevent your coils from freezing up is to make sure that you clean them regularly. At times, evaporator coils can collect debris and dirt quickly, so monthly cleaning may be needed. Typically, however, evaporator coils need to be cleaned every three months or so.
If the buildup of dirt on the evaporator coil is not that heavy, using compressed air will often suffice. It is recommended that the compressed air is directed opposite the normal airflow across the evaporator coil. It is also vital that you wear eye protection. A brush can be very effective at removing heavier amounts of dirt from a dirty evaporator coil. Using a brush is also a great option since you are more in control of the pressure you will apply and the areas you are cleaning. Cleaning with a brush will make it very easy to sweep the dirt away. When using a brush to clean the evaporator coils, opt for a soft one so you won’t damage the fins.
If your coils are covered in heavy dirt and other substances, you can opt for a commercial cleaner. When it comes to cleaners, you’d be delighted to know you have plenty of options available on the market. Once you have chosen a brand, follow the instructions provided by the manufacturer. Also, allow the cleaner to sit and foam until the debris, and the foam is drained away. Reapply as needed or according to instructions or until the coils are clean.
Change air filters regularly.
Most people don’t think about their air filters until they start having problems with their HVAC system. Contrary to popular belief, air filters are not just there to keep your system clean, they also play a very important role in your comfort. When air filters are clean, they provide clean, fresh air for your home and improved indoor air quality. However, when they’re dirty, your comfort could be in jeopardy. In fact, a dirty air filter can lead to reduced airflow and frozen evaporator coils.
This is because a dirty air filter can impede airflow and prevent the coils from maintaining the right temperature. Dirty air filters lead to a number of problems, including a decrease in comfort and an increase in your energy bills. Most experts recommend changing your air filters every three months. However, if you have pets or if you smoke, you may need to change them more often.
Repair any leaks in your ductwork or refrigerant lines.
To prevent your evaporator coils from freezing over, it is important to ensure there are no leaks in your ductwork or refrigerant lines. If there are any leaks in your ductwork, they will need to be repaired in order to keep the cold air inside your house and the warm air outside. When you have air leaks, it could impact the temperature around your coils and cause them to freeze. You should also check the insulation on your ducts to make sure it is adequate and seal any cracks or holes you find. It is also important to keep the area around your evaporator coils clean and clear of debris so the airflow is not restricted.
Additionally, you need to make sure that there aren’t any leaks in your refrigerant lines. If your lines have developed a leak, the refrigerant will escape from your AC unit. As a result, the refrigerant levels could drop and create a lower temperature in the coils as the refrigerant expands. When this happens, your coils will freeze over. A qualified HVAC technician will need to inspect and repair any problems with refrigerant lines.
There are many benefits to keeping your evaporator coils clean and free of obstruction. Not only does it help the system run more efficiently, but it can also prevent the coils from freezing. By following a few simple tips, you can keep your evaporator coils clean and running smoothly all summer long.
