Echo Park bedroom temperature, noise, and airflow at 11 p.m.
Electric service in Echo Park is LADWP; gas is SoCalGas. Equipment selection should match the rebate path that utility offers when the program applies on the day the contract is signed. LADWP time-of-use schedules also shape the right answer for Echo Park sleep cooling — running a heat pump from 9 p.m. through 6 a.m. on off-peak rates costs less than running an oversized central system that short-cycles at 3 a.m.
Marcus Reyes, P.E. models the 9 p.m.–6 a.m. window separately during the audit, because that is the only window that matters for the actual complaint.
