COOL AND HEAT A WORKSHOP (MINI SPLIT)
Compact and quiet, mini- splits are very safe for installation in woodshops, as they produce no flame, nor do they have hot elements, and the indoor unit’s coils never get hot enough to ignite dust and other flammables.
These cooling units work just like home central-air units: an outdoor compressor coupled with an indoor cooling coil, but in miniature. The lightweight, outdoor compressor takes up little room, the interior cooling unit can be hung anywhere (no ducting necessary), and the connecting refrigerant and electrical lines require only a 3" hole through the wall.
For an added cost, many mini-split units offer a heat pump upgrade, adding the capability of drawing heat from the outdoor air and depositing it inside.
They’re simpler and less expensive to install than heating systems that require ductwork. They’re also more efficient and cheaper to run than typical electric heaters, thanks to inverter technology that allows their compressors to operate at variable speeds, delivering only as much heating/cooling as needed.
