1.5HP Split Type Aircons That Use the Least Electricity, Ranked by CSPF

The 1.5HP split type aircon that uses the least electricity, among verified models, is the TCL TAC-14CSD/P7 (FreshIN 3.0): CSPF 6.74 on its DOE label, 1,000 W rated input and 3.89 kW rated capacity. The TCL TAC-12CSD/FBI (CSPF 6.34, 1,130 W) is second, and the Samsung AR60H13D1FWNTC (CSPF 5.70, 1,030 W) is third.

How we ranked them

CSPF first, then rated watts. CSPF is the label’s “Energy Efficiency Rating”: the cooling delivered per kWh over a standard cooling season. We ranked only models with rated watts and CSPF from a DOE label or the manufacturer.

What stands out

The P7 is the most efficient and the biggest. It has the highest CSPF, the lowest rated watts and the most capacity (3.89 kW) of any verified 1.5HP split. Low watts here don’t mean a small unit.

Same capacity, very different running costs: FBI vs KEI2. Both TCL units are rated 3.61 kW and 13,000 kJ/h for 15–23 sqm. The FBI does it at 1,130 W and CSPF 6.34; the KEI2 at 1,300 W and CSPF 4.92. For the same room, the FBI is the clear choice on electricity. TCL’s FBI spec sheet lists a rated current of 4.7 A, a maximum of 8.5 A and a maximum input of 1,900 W.

Samsung is a close third on watts. At 1,030 W it is only 30 W above the P7. SM Appliance also lists an EER of 12.29 kJ/h per W. Its label monthly figure (139.05 kWh) can be compared with the P7’s (135 kWh) because both labels were issued in the same year. As a check, 1.03 kW × 9 hours × 30 days × 0.5 = 139.05 kWh, the DOE formula for inverter units on older labels.

Midea Chione: watch which watts you read. Midea lists 1,250 W at standard cooling conditions. A retailer also shows a “rated input power” of 2,050 W, which looks like a maximum. Use Midea’s figure.

Example monthly cost

Example only: 8 hours a night, 30 days, at an example rate of ₱12 per kWh (your own rate: electricity rates page). The “example factor 0.5” is the DOE’s older-label assumption that an inverter averages half its rated input; real use depends on your room.

On these example assumptions, the P7 costs about ₱432 a month less than the KEI2. Over a hot season of heavy use, that gap matters. Run your own hours in the aircon electricity cost calculator.

Not ranked (data not confirmed)

• Midea MSAS-13CRFN8: a listing claims CSPF 7.3, but no rated watts or label were confirmed.
• Midea MSCE-13CRFN8: listing-only CSPF, no rated watts.
• Samsung AR40H12D1ATNTC, Haier HSU-13PSV35-W, AUX ASW12A2/QGDI, Astron TCLSPV150: no specs we could confirm from a label or maker.

Where to buy

• TCL TAC-14CSD/P7 (choose 1.5HP): Lazada · Shopee (TCL Official Store)
• TCL TAC-12CSD/FBI (choose 1.5HP): Lazada · Shopee (TCL Official Store)
• Samsung AR60H13D1FWNTC: Shopee (Samsung AI Home)
• Midea MSCH-13CRFN8 (choose 1.5HP): Shopee (Midea Official Store)
• TCL TAC-13CSD/KEI2: Lazada · Shopee (TCL Official Store)

Several are series listings, so choose 1.5HP and confirm the model code. A split needs refrigerant piping and proper wiring, so have a licensed technician or authorised installer fit it.

Bottom line

For a 1.5HP split, the TCL TAC-14CSD/P7 is the most efficient verified choice, with the TCL TAC-12CSD/FBI close behind. The Samsung AR60H13D1FWNTC is a solid third. If you’re comparing against a window unit, see window vs split: which uses less electricity.
