How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, TAC-08CHPD/DM1SGBp. DOE's definition of a basic model (10 CFR 430.2) covers "all units of a given type of covered product (or class thereof) manufactured by one manufacturer" with "the same primary energy source" and nearly identical "electrical, physical, and functional (or hydraulic) characteristics that affect energy consumption, energy efficiency, water consumption, or water efficiency." So one set of DOE figures covers every name on the list. No brand files TAC-08CHPD/DM1SGBp itself as a model number. It's the code DOE uses to tie their filings together.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: SereneLife SLINV12CPD.

How much does the TAC-08CHPD/DM1SGBp cost to run?

8,200 BTU/h SACC divided by a CEER of 12 is about 683 W while cooling. That's about 12¢ an hour, or $29.78 for 30 days at 8 hours a day.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

Who makes the TAC-08CHPD/DM1SGBp, and is it the same under every brand?

Who makes the TCL T08PQ4SD?: DOE's records don't say. The TCL T08PQ4SD is filed under basic model TAC-08CHPD/DM1SGBp along with the SereneLife SLINV12CHPD. Neither brand files TAC-08CHPD/DM1SGBp itself as a model number, and DOE's database has no manufacturer field.
Is the TCL T08PQ4SD the same as the SereneLife SLINV12CHPD?: Yes, by DOE's records. Both are filed under basic model TAC-08CHPD/DM1SGBp and list the same certified figures: 8,200 BTU/h SACC, CEER 12 and dual hose.
Which brand of TAC-08CHPD/DM1SGBp is cheapest to run?: They tie: every brand files 8,200 BTU/h SACC, CEER 12 and dual hose, so each costs about 12¢ an hour to run while cooling.
