Leroy Merlin has just reduced the price of the Equation Cool&Heat 9K portable air conditioner to €259, offering a quick way to climate-control your home without renovations or installers. This versatile unit not only cools in summer but also heats in winter thanks to its heat pump technology.
Why the Equation Cool&Heat 9K Stands Out
Unlike typical portable ACs that gather dust after summer, this model integrates a heat pump that turns it into an efficient heating system for colder months. It also functions as a fan and dehumidifier, making it a year-round ally against humidity and temperature extremes.
With a cooling capacity of 2,236 frigorías (approximately 9,000 BTU), it suits medium-sized rooms. Its Plug & Play design means no drilling or professional installation—just place it near a window, attach the hose with the included kit, and you're set.

Key Features and Benefits
- 2-in-1 functionality: Cools and heats using heat pump technology.
- No installation required: Plug & Play setup with window kit included.
- Versatile modes: Fan and dehumidifier functions for year-round use.
- Medium-room capacity: 2,236 frigorías suitable for living rooms or bedrooms.
- Budget-friendly: Now €259 at Leroy Merlin.
How It Compares to Other Portable ACs
| Feature | Equation Cool&Heat 9K | Typical Portable AC |
|---|---|---|
| Heating function | Yes (heat pump) | No |
| Installation | Plug & Play | Often requires window kit |
| Dehumidifier | Yes | Sometimes |
| Price | €259 | Varies, often higher |
This comparison highlights the Equation's unique heating capability, which is rare in portable ACs. While it may not be the quietest unit on the market, its versatility justifies the trade-off for many users.
Who Should Consider This Portable AC?
This unit is ideal for renters or homeowners who want to avoid permanent installations. It's also perfect for those who need occasional heating in transitional seasons or rooms without central HVAC. The dehumidifier function adds value in damp climates, improving indoor comfort.
However, if you require silent operation or have very large spaces, you might need a different solution. For most average-sized rooms, the Equation Cool&Heat 9K delivers solid performance at a competitive price.

What to Watch Next
As energy costs fluctuate, efficient heating and cooling solutions become more attractive. Keep an eye on Leroy Merlin's promotions, as this price may be temporary.
