Ductless Mini-Splits in Roseville, CA: A Troubleshooting Guide

Many homeowners in Roseville, CA, like ductless mini-split air conditioning systems for their efficiency, reliability and low noise. Like all HVAC equipment, mini-splits might experience operational issues over time. Let's explore some of the common problems and tips for troubleshooting ductless mini-splits.

Leaking Condensate

Mini-splits have lines running from the outdoor condenser that carry refrigerant to the indoor units for sufficient cooling. Condensation builds up on the outer surface of the line. This moisture drips and collects in a pan, where it then flows into a condensate drain.

If you see leaks on your wall or floor, there may be a clog in the condensate drain, and it isn't doing its job of removing the moisture. When this happens, it's wise to contact your ductless AC service professional for a repair before there's damage to your home's interior surfaces.

Malfunctioning Blower Fan

Unlike a ducted AC system with one air handler, each mini-split has its own fan to circulate cool air inside your home. If you turn on the unit and don't feel any air flowing from it, chances are good that the blower isn't working. Your HVAC specialist will inspect the system to determine if there is an electrical wiring connection issue, a broken fan motor or a defective circuit board.

Inadequate Cooling

There are instances when your mini-split cannot sufficiently cool a room on a hot summer day. This could be due to a dirty filter that needs cleaning. Or, it might be that the system isn't the right size for the volume of space it's cooling.

Broken Compressor

The outdoor condenser of your mini-split system houses the compressor. Its job is to compress the refrigerant that is necessary to cool your home. If your system is running nonstop but not providing adequate cool air, it's possible that the compressor isn't working and needs repair or replacement.

When you suspect your ductless mini-split in Roseville, CA, isn't adequately cooling your home in the heat of summer, this guide will help you understand what the issue may be. Call Jaguar Heating & Air, whether you need a comprehensive diagnosis of the system and its components or a new AC installation.
