Repairs a Ductless Heating System May Need
Ductless systems are a unique and effective way to heat your home. Like all heating systems, however, they occasionally run into issues. Ductless heating systems are not combustion-based, so a lot of the problems they experience are very different from your standard boiler or furnace problems. Let’s take a deeper look at the repairs a ductless heating system may need, and how you can identify them.
REFRIGERANT LEAKS
Refrigerant is a vital part of a ductless heating system’s operation. When the heating system turns on, the outside unit uses an evaporator coil to convert refrigerant inside the coil into gas. This turns the refrigerant into a heat sink, leeching heat out of the air around the unit and into the coil. The refrigerant then carries the thermal energy through the refrigerant line and into the indoor unit, which converts the refrigerant back into a liquid. This releases the thermal energy so that it can heat the room.
Refrigerant is not consumed by the ductless heating system. Instead, it is recycled each time the heating is turned on. A refrigerant leak is a major problem because it drains refrigerant from the system, making it unable to transport heat into the home. If you notice any pooling or dripping liquid around your ductless unit, call a professional right away.
BROKEN DEFROST CYCLE
When the ductless heating system’s outdoor unit evaporates refrigerant to draw in heat, it also creates condensation on the coil itself. The combination of condensation on the coil and a drop in the surrounding air temperature can cause ice to begin forming on the unit. All ductless heating systems are designed with a defrost cycle, to melt the ice off of the unit. If the defrost cycle isn’t working, however, ice can build up until it covers the entire outdoor unit. This cripples the whole system by depriving it of the air that it needs to siphon thermal energy from.
