Sleep cooling in Los Feliz: what the bedroom actually needs
For households on a LADWP schedule with a 92°F design temperature and a Manual J band of 380-500 sq ft per ton, the sleep-room solution path forks early. Single-zone ductless suits two-bedroom and three-bedroom layouts where the master is the only complaint. Multi-zone ductless or true zoning suits four-bedroom-plus layouts where two rooms compete. A heat-pump replacement of the central system suits homes already due for equipment turnover.
Marcus Reyes, P.E. does not recommend the third option unless equipment age, refrigerant type, or duct condition would force replacement within five years anyway.
