How to choose a 12000 BTU portable air conditioner with hot and cold function for your home

12000 BTU represents an intermediate power level, suited to small and medium residential spaces. A BTU (British Thermal Unit) measures cooling or heating capacity. To determine if this power is right for you:

• Measure the room surface area (length × width)
• Consider sun exposure and insulation
• Check the number of windows and doors

A 12000 BTU portable air conditioner effectively cools 25 to 35 m² under normal conditions. In very sunny areas or poorly insulated spaces, reduce this estimate. Tempéra offers certified models meeting these standards.

Beyond power output, several factors influence your choice:

Energy efficiency: Look for a high coefficient of performance (COP) to reduce your electricity bills.

Noise level: A quiet portable air conditioner (below 65 dB) ensures acoustic comfort in the living room or bedroom.

Hot/cold mode: The reversible function allows cooling in summer and supplementary heating in winter, optimising year-round use.

Mobility: Check the weight, wheels and ease of installation without permanent works.

Control: Opt for an intuitive remote control and ideally hourly programming.

The main advantage of a portable air conditioner is the absence of major works. Simple installation: place the unit near a window, insert the hot air exhaust hose, plug it in.

To optimise performance:

• Close the doors of the cooled room
• Position the unit away from obstacles
• Clean the filters monthly
• Drain or evacuate condensation water (depending on the model)

Regular maintenance extends the lifespan and maintains energy efficiency. Tempéra air conditioners feature automatic drainage systems to simplify this daily maintenance.
