Ductless heat pumps connect their outdoor units to their indoor units through a combination of power cables, refrigerant lines, suction tubing and condensation drain lines.

If you are making a refrigerant circuit repair, weighing out and weighing in makes perfect sense, especially since microchannel condensers and scroll compressors make pumping down less viable anyway.

The mini split system relies on a complex heat exchange process involving the cyclical condensation and vaporization of the hot air that the indoor unit removes from the living space.

The refrigerant is piped to condenser/evaporators in each room, allowing greater control over temperature in each room. Because it requires more condenser/evaporators, mini-split systems are ...

As mini-split air conditioning units trend during the South Central Texas heat wave, here are the advantages and disadvantages for San Antonio residents.
