Possible Reasons Your Ductless AC Isn't Cooling Your Home
A ductless AC is an efficient and convenient way to cool your home. Since the system has no ducts, you won't have to worry about duct problems interfering with how well the AC works. However, there are still a few things that can go wrong with a ductless system. Here are some reasons why your ductless air conditioner may not be cooling your home properly.
Problems With Air Flow
The filter in a ductless air conditioner can get dirty and clog up over time. It's important to clean it regularly so air can flow through the blower. When your AC isn't keeping you cool, check the filter first. If it's coated with dust, then clean it and see if your AC starts cooling. If dust builds up, it's possible ice can form on the blower due to low airflow. If that happens, turn the unit off and give the ice time to melt. With a clean filter and the ice gone, your AC may work properly again. Also, check that nothing is against the outdoor unit that's blocking airflow. Proper air circulation is necessary for the proper functioning of any air conditioner and a ductless system is no exception.
Low Refrigerant Pressure
When the refrigerant level is low, your AC won't keep your home as cool. Not only that, running the AC with low refrigerant can lead to other problems. It can cause the coils to ice over and it can also cause damage to the compressor. A licensed technician is needed for work on a ductless refrigerant line. First, the leak has to be found. Then the hole is repaired and the refrigerant is filled to the proper pressure. The refrigerant shouldn't leak out normally, so if it does you know there's a leak that needs to be repaired.
Worn Out Parts
Like anything mechanical, the parts in a ductless system wear down and need to be replaced. There could be problems with the motor in the indoor blower or the capacitors might fail and no longer be able to carry an electrical charge to operate the AC. The condenser motor might also be bad. The technician can check your ductless system and make repairs as needed, but sometimes repairs can be avoided by having annual maintenance done before problems develop.
Your ductless AC may display error codes when it's malfunctioning. You can look up the meaning of the code in your manual or online. Knowing the cause of the problem helps you zero in on the right repairs, but making repairs beyond cleaning the filter is usually a job for a professional so you stay safe and protect the warranty of your system.
