Quick verdict
For most people, the Philco Inverter 3750W heat/cool is the best buy: low consumption, A++ efficiency and solid power. If you want to spend little, the BGH 3100F; if you want premium with Wi-Fi and app control, the Hyundai Inverter.
What to look for before buying
- Cooling power (frigorías) — This comes first: a room up to 15-20 m² needs about 2200-2500 frigorías; 30-40 m² about 4500-5000. If you go too small, the unit runs at full tilt and cools poorly.
- Inverter vs. on/off — An inverter modulates power instead of switching on and off: it uses noticeably less electricity, cools more evenly and runs quieter. Worth it if you'll use it a lot.
- Heat/cool — A heat/cool unit works all year: it cools in summer and heats in winter, often cheaper than an electric heater.
- Energy efficiency — The label (A, A+, A++) shows how much it consumes. An A++ inverter costs a bit more but pays for itself on the electricity bill if you use it often.
- Brand and service — Brands with local service (Philco, BGH, Hyundai) make installation, warranty and spare parts easier. It matters for a unit that lasts years.

A good split air conditioner sorts out your summer and, if it’s heat/cool, your winter too. The keys are choosing the right cooling power for the room size and deciding whether the inverter is worth it for the energy savings. We compared the best sellers on MercadoLibre Argentina.
What to look for
- Cooling power: up to 15-20 m² about 2200-2500 frigorías; 30-40 m² about 4500-5000. Too small and the unit runs flat out and cools poorly.
- Inverter: modulates power instead of switching on and off. Uses less electricity, cools more evenly and runs quieter.
- Heat/cool: works all year and usually heats cheaper than an electric heater.
- Efficiency: the label (A, A+, A++) shows consumption. An A++ pays for itself on the bill if you use it often.
Our pick

Frequently asked
How many frigorías do I need?
It depends on the area and sun exposure. As a guide: up to 15-20 m² about 2200-2500 frigorías; 20-30 m² about 3000-3500; 30-40 m² about 4500-5000. If the room gets a lot of sun or has high ceilings, size up one step.
Is an inverter worth it even if it costs more?
If you'll use it often, yes: an inverter modulates power and uses noticeably less than an on/off, plus it cools more evenly and runs quieter. The price difference is recovered on the electricity bill over time.
Does a heat/cool AC replace a heater?
Largely yes: a heat/cool split heats efficiently, often cheaper than an electric heater. For very cold winters, go for an inverter model, which holds its heating performance better.
Are the prices and stock up to date?
Yes: we pull real prices and availability from MercadoLibre Argentina. They can change at any time; the link always takes you to the current offer.
Before you choose, read this
- How much electricity does an air conditioner use per hour? A 12,000 BTU split uses between 0.9 and 1.4 kWh per hour depending on its efficiency, but only while the compressor is working. That's the key: a conventional unit switches on and off at full power, while an inverter lowers its output once it reaches temperature and so uses considerably less over long sessions.
- How many BTU do I need for my room? The base rule is 200 BTU per square metre (50 frigorías) in a normal room: 9000 BTU for 45 m², 12,000 BTU for 60 m². Add 20-30% if the room gets direct sun, has large windows, an uninsulated roof, or is on the top floor.
