Mini-split systems are complex and can experience a range of issues. Our experienced technicians have seen it all and are equipped to handle any problem, big or small. If you notice any of the following signs, it’s time to call for a professional diagnosis.
This is the most common and critical issue. The cause can range from something as simple as a thermostat miscommunication to a more serious problem like a refrigerant leak, a failing compressor, or a faulty reversing valve. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause and perform the necessary repair.
Water dripping from your indoor unit is a clear sign of trouble. This is often caused by a clogged condensate drain line, which prevents moisture from being properly removed from your home. If left unaddressed, this can lead to water damage, mold growth, and potential system failure. We can clear the blockage and ensure your system drains correctly.
Your mini-split should operate almost silently. If you hear grinding, rattling, buzzing, or gurgling sounds, it indicates an internal problem. These noises could be caused by a failing motor, debris in the fan, or issues with the refrigerant lines. Ignoring these sounds can lead to more severe and costly damage.
A musty or foul smell coming from your mini-split is often a sign of mold or mildew buildup on the evaporator coils or within the unit. This not only creates an unpleasant environment but can also negatively impact your home’s air quality. We provide thorough cleaning and sanitation services to eliminate odors at their source.
If your mini-split is running constantly or working harder than usual to maintain the set temperature, it will consume more energy. This inefficiency can be caused by dirty filters, low refrigerant levels, or a failing component. We can identify the source of the inefficiency and restore your system’s energy-saving performance.
Short-cycling is when your system turns on and off frequently without completing a full cooling or heating cycle. This puts excessive wear and tear on the compressor and other components. It can be caused by an oversized system, a refrigerant leak, or a faulty thermostat.
We believe in a transparent and thorough approach to every repair job. When you entrust us with your mini-split system, you can expect a professional process from start to finish.
