Watch for These Ductless AC Repair Issues

Using a ductless cooling and heating system (a.k.a. a ductless mini split heat pump) is an excellent way to enjoy comfort around the year in your home. One of the best benefits of a ductless system is that you won’t run into any repair issues connected to ductwork—for obvious reasons! Of course, there are still malfunctions that can affect a ductless mini split system that will require you to call for ductless AC repair in Cottage Grove, OR. We’ll look over several of the more common ones below. Keep a watch for these this summer!

Refrigerant Leaks

Refrigerant leaks are one of the most common issues with ductless mini split systems. When your system is low on refrigerant, it can’t effectively cool or heat your home. Signs of a refrigerant leak include decreased cooling or heating efficiency, ice buildup on the evaporator coils, and hissing or bubbling sounds near the outdoor unit. You need to address refrigerant leaks promptly, as they not only hurt system performance, they can also lead to a compressor burnout.

Electrical Problems

Ductless mini splits are electrical devices, so issues such as faulty wiring, blown fuses, or tripped circuit breakers can lead to system failures. If your unit isn’t turning on or is experiencing intermittent power issues, it’s likely an electrical problem. Attempting to fix electrical issues on your own can be dangerous and may void your warranty. It’s best to call a professional HVAC technician to safely diagnose and repair the problem.

Sensor Malfunctions

Your ductless mini split uses sensors to monitor the temperature and adjust the system accordingly. If these sensors are misaligned or malfunctioning, they can send incorrect readings to the system, leading to inefficient operation. Symptoms of sensor issues include the system running continuously without reaching the desired temperature or shutting off prematurely.

Drainage Issues

Proper drainage is crucial for your ductless mini split to work correctly. Over time, the condensate drain can become clogged with dirt, debris, or mold, leading to water leakage or increased humidity levels indoors. If you notice water leaking around the indoor wall-mounted units or an unusual increase in indoor humidity, it’s likely a drainage problem. Clearing blockages in the condensate drain requires specialized equipment and knowledge, making it a task best left to professionals.

Fan Problems

The fans in your ductless mini split are responsible for blowing air from the wall-mounted units into the rooms. Issues such as a malfunctioning fan motor, damaged fan blades, or worn-out bearings will hinder airflow, reducing the system’s efficiency. If you hear strange noises coming from the indoor or outdoor units, or if the airflow seems weak, it’s time to call an HVAC technician. 

Dirty Coils and Filters

Both the indoor and outdoor units of your ductless mini split system have coils and filters that need to be clean to function correctly. Dirty coils can reduce the system’s ability to transfer heat, while clogged filters can restrict airflow, forcing the system to work harder. If your system is already experiencing reduced efficiency, have a professional perform a thorough cleaning and inspection.

Remote Control Issues

Ductless mini splits often come with remote controls for convenient operation. If your remote control stops working or isn’t communicating with the system, it could be due to dead batteries, a malfunctioning sensor in the indoor unit, or other technical issues. While replacing the batteries is a simple fix, more complex problems require the expertise of an HVAC technician to diagnose and resolve.
