Choosing the right portable air conditioner depends on your priorities: power, versatility, mobility or budget. Here's a detailed comparison of three flagship models from our range to help you decide.

Important selection criteria:

  • Cooling capacity (BTU): 9000-12000 BTU for 20-35 m², 5000-7000 BTU for under 15 m²
  • Energy consumption: opt for class A or A+ models (visible savings on your bill)

Installation and Maintenance: Simpler Than You Think

One of the major advantages of a portable air conditioner is its ultra-simple installation. Unlike fixed air conditioners, no drilling, no complex wiring.

Installation steps (5 minutes):

1. Unpack the appliance and position it near a window or opening

2. Insert the exhaust hose into the window kit provided

3. Plug the appliance into a standard socket

4. Set the temperature and desired mode

5. Enjoy immediate cooling

Minimal maintenance:

  • Clean the filter every 2 weeks (5 minutes)
  • Drain the condensation tank if necessary (depending on model)
  • Store the appliance in a dry place in winter

Tempéra models include all necessary accessories. No mandatory additional purchases. Our support team is available to answer your technical questions.

Energy Consumption and Real Savings

In 2026, the energy efficiency of portable air conditioners has reached a remarkable threshold. A modern appliance consumes between 600 and 1500 W depending on power, which is 2 to 4 times less than a traditional fixed air conditioner.

Estimated annual costs (based on 8 hours/day for 4 months, average rate €0.18/kWh):

  • 12000 BTU class A+ air conditioner: ~€120-150/year
  • 12000 BTU class B air conditioner: ~€180-220/year
  • Portable split air conditioner: ~€80-100/year

Tips to reduce your consumption:

  • Use "eco" or "smart" mode (reduces consumption by 20%)
  • Set a timer (switch off the appliance at night)
  • Close doors and windows during cooling
  • Clean filters regularly (a dirty filter increases consumption by 15%)

Tempéra models all feature inverter technology, which automatically adjusts power according to real needs. Result: savings without loss of comfort.

FAQ

Which portable air conditioner should I choose for a small flat (20 m²)?

For a small space, the [12000 BTU Portable Air Conditioner 3-in-1](climatiseur-portable-12000-btu-3-en-1) is ideal. With 12000 BTU, it cools quickly without over-powering. Its versatility (cold, dehumidification, ventilation) and attractive price (£999) make it the best choice for small budgets. Alternative: the camping split for even more savings.

Does a portable air conditioner really consume less than a fixed air conditioner?

Yes, approximately 40-50% less. A class A+ portable air conditioner consumes 1100-1200 W, compared to 2000-2500 W for an equivalent fixed unit. Moreover, you only cool occupied zones, not the entire house. Over a summer season (4 months), savings exceed £100. Tempéra models with inverter technology further optimise consumption.

Can I use a portable air conditioner for camping or in a caravan?

Absolutely. The [1500W Split Portable Air Conditioner Camping & Indoor](climatiseur-portable-split-1500w-camping-interieur) is designed for this. Robust, lightweight, with long-lasting battery autonomy, it adapts to nomadic conditions. Check your caravan's electrical capacity (generally 16A is sufficient for this model).

What is an acceptable sound level for a portable air conditioner?

Less than 25 dB is excellent (comparable to a whisper). Between 25-30 dB remains acceptable for most uses. Beyond 30 dB, noise becomes disruptive for sleep or concentration. All Tempéra air conditioners stay below 25 dB, guaranteeing optimal comfort even at night.

Do I need to exhaust hot air through a window?

Yes, it's essential. The portable air conditioner expels hot air via a hose that must exit through a window, door or duct. All our models include a simple window kit (no drilling required). Without exhaust, the appliance won't cool effectively.

Which air conditioner for year-round use (cold AND heat)?

The [12000 BTU Portable Air Conditioner Hot & Cold](climatiseur-portable-12000-btu-chaud-froid) is your best ally. Reversible, it cools in summer and heats in winter (integrated heat pump). At £1149, it's a unique investment for 12 months of thermal comfort. Ideal for regions with mild winters.

How do I clean and maintain my portable air conditioner?

Simple: clean the filter every 15 days (5 minutes under warm water), drain the condensation tank if necessary (depending on model and humidity), and store the appliance in a dry place in winter. No costly technical maintenance. Tempéra models are designed for maximum durability with minimal maintenance.

What's the difference between a monoblock and a portable split air conditioner?

The monoblock (our 12000 BTU models) is simple, inexpensive, ideal for most uses. The split (camping) separates the indoor unit from the outdoor unit, offering more discretion and less noise. Choose the monoblock for power, the split for aesthetics and mobility.

Are Tempéra air conditioners really quiet?

Yes, all our models display less than 25 dB (equivalent to a whisper). Thanks to inverter technology and reinforced sound insulation, you can sleep, work or relax without noise disturbance. It's one of our key guarantees.

What is Tempéra's warranty and customer support?

All Tempéra portable air conditioners benefit from a 3-year warranty (parts and labour). Our customer support is available 24/7 by phone, email and chat. We test each product before dispatch and offer a 30-day returns policy with no conditions.
