Going to soon be renovating a small commercial building (roughly 2000 sq feet, 45 ft x 45 ft). To maximize interior space the owner is suggesting an outdoor HVAC unit.
Building is single-floor, concrete block walls, climate is similar to Detroit / Cleveland / Buffalo / Toronto.
Any major drawbacks to locating the HVAC unit outside?
Any suggestions as to make/model of unit?
Thanks for any tips.
