2HP and Bigger Split Type Aircons That Use the Least Electricity

The 2HP split type aircon that uses the least electricity, among verified models, is the TCL TAC-19CSD/P7 (FreshIN 3.0): CSPF 7.02 on its DOE label, 1,450 W rated input and 5.42 kW rated capacity. For 2.5HP and 3HP, the verified choices with store links are the Midea MSCH-22CRFN8 (CSPF 5.83, 2,149 W) and Midea MSCH-25CRFN8 (CSPF 5.63, 2,512 W).

How we ranked them

Within each HP size, by CSPF first and rated watts second. CSPF is the “Energy Efficiency Rating” on the DOE label: cooling per kWh over a standard season. We only ranked models with rated watts and CSPF confirmed by a DOE label or the manufacturer.

What stands out

At 2HP, the P7 saves real electricity. The TCL P7 and TCL KEI2 2HP are almost the same size (5.42 kW vs 5.44 kW), but the P7 is rated 450 W lower and has a much higher CSPF. Their labels were issued in the same year, so the monthly figures compare fairly: 195.75 kWh for the P7 against 256.5 kWh for the KEI2 on the label’s 9-hours-a-day basis. That is 60.75 kWh a month less, or about ₱729 a month at an example rate of ₱12 per kWh.

Midea sits in the middle at 2HP. The Chione MSCH-19CRFN8 is rated 1,758 W with a retailer-listed CSPF of 5.63. Midea lists a rated current of 7.64 A. A retailer also shows a “rated input power” of 3,000 W, which looks like a maximum; we use Midea’s figure.

Bigger sizes: only Midea is verified with a listing. The 2.5HP MSCH-22CRFN8 (9.34 A rated) and 3HP MSCH-25CRFN8 (10.92 A rated) are the only verified options at those sizes with linked stores. A TCL 3HP KEI2 label exists (2,840 W, CSPF 5.86), but we couldn’t confirm a linked listing that sells it.

Size for the room. Match the suggested area and rated capacity to your room. Our aircon electricity consumption guide explains why horsepower is a size class, not a wattage.

Example monthly cost

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

Not ranked (data not confirmed)

• Midea MSAS-19CRFN8 / MSAS-25CRFN8: listings claim CSPF 6.9 and 5.6, but no rated watts or label were confirmed.
• Everest ETIV20CFWD/G 2HP window: listing figures only, with an unverified “saves up to 60%” claim.
• Tixx 2.0HP portable: no model code or specs could be verified.
• Astron TCLSPV200 and Hisense 2HP+ splits: no specs we could confirm.

Where to buy

• TCL TAC-19CSD/P7 (choose 2HP): Lazada · Shopee (TCL Official Store)
• TCL TAC-19CSD/KEI2 (choose 2HP): Lazada · Shopee (TCL Home)
• Midea Chione MSCH-19CRFN8 / MSCH-22CRFN8 / MSCH-25CRFN8 (choose 2HP, 2.5HP or 3HP): Shopee (Midea Official Store)

These are series listings, so pick the HP and check the model code before paying. At these sizes the aircon needs the right wire size and breaker. Have a licensed electrician check the circuit, and have a licensed technician or authorised installer fit the split.

Bottom line

For a 2HP split, the TCL TAC-19CSD/P7 is the most efficient verified choice by a wide margin. For 2.5HP and 3HP, the Midea Chione units are the verified options with store links.
