The Possibilities Are Endless

Ductless HVAC systems offer an energy-efficient, space-saving, and convenient way to heat and cool your Las Vegas, NV home. Many people prefer them for finished basements, additions, and homes with open floor plans. If you’re considering investing in a ductless HVAC home comfort system, it’s important to know what types of problems are common in them. If you notice any of these issues, you’ll need ductless HVAC repairs.

Refrigerant Leak

Each indoor unit of the ductless system has its own conduit to the outdoor unit. The refrigerant tubing runs through the conduit. These systems are more prone to refrigerant leaks than central air conditioners because they have more linear footage of tubing for the refrigerant. If you notice frequent cycling, poor temperature or humidity control, or no cold air blowing from one or more indoor units, it probably has a refrigerant leak. This situation requires a qualified service technician to perform ductless HVAC repairs.

Clogged Condensate Drain

Each indoor unit in a ductless HVAC system also has its own condensate drain. This drainpipe runs through the conduit, along with the refrigerant tubing and the electrical wiring. If the condensate pipe becomes clogged, water will leak from it. This leak could develop within the indoor unit or anywhere along the conduit. You’ll notice condensation or dripping from the wall or ceiling. A clogged condensate line requires urgent ductless HVAC repairs by a qualified service technician.


According to the Department of Energy, short-cycling is a common problem with ductless HVAC systems. This happens when the unit runs for a short time, turns off for a moment, and turns on again within one minute. Short-cycling may result from a safety limit switch tripping, incorrect system pressure, or an improperly located thermostat or indoor unit.
