A ductless mini-split system offers several advantages to your Greenville, SC, home, including improved energy efficiency, comfort, convenience and zone control. However, your mini-split system may have an issue and and fail to deliver hot and cold air in the home. You should contact your local HVAC technician, who will diagnose and solve the problem.

A Malfunctioning Reversing Valve

Some ductless mini-split systems are heat pumps, and this heat pump has a reversing valve. The reversing valve’s main job is to change the refrigerant flow direction to allow adequate heating and cooling of the home. Sometimes, the reversing valve will develop a leak or won’t rotate, affecting its functioning.

A Broken Indoor Air Handler

You can mount your indoor air handler on the ceiling or the wall of different rooms. The work of the indoor air handler is to transfer conditioned air directly to your living area. One of the air handlers’ motors can break down, which will affect how the unit delivers the conditioned air.

The best thing is that indoor air handlers work independently, so the failure of one unit doesn’t affect the other units. Therefore, as you arrange to have the broken air handler fixed or replaced, the other rooms in the house will remain cool.

Refrigerant Leaks

Refrigerant leaks can be fairly easy to fix but sometimes are catastrophic because they can destroy the compressor, forcing you to replace the entire outdoor unit. Since ductless mini-splits have several refrigerant lines and great outdoor exposure, they’re more likely to experience refrigerant leaks.

You can detect refrigerant leaks by looking out for these signs: loss of cooling power from the air handler and ice cooling on the air handler’s coil. However, scheduling regular maintenance services for your ductless unit will allow the technicians to detect the refrigerant leaks in time and prevent further damage.

Clogging of the Condensate Line

Ductless mini-split systems have condensate and refrigerant lines. This means that they’re prone to clogging, and this affects the functioning of the blower.
