When choosing a climate control system, consider whether a portable or fixed air conditioner is better for you. Portables, like the Midea PD models, offer flexibility and easy installation without construction, ideal for small spaces. Fixed units provide greater efficiency and comfort in large areas.

When choosing a climate control system, one of the main questions is whether to opt for a portable air conditioner or a fixed split-type air conditioner. Both solutions have advantages and disadvantages in terms of energy efficiency, cost, comfort, maintenance, and flexibility of use.

In this article, we thoroughly analyze each option to help you decide which one best suits your needs. Additionally, we present three Midea portable air conditioner models that stand out for their performance and eco-friendly technology based on R290 refrigerant gas:

Portable air conditioner cold R290 Midea PD 2.5 kW (Reference 13907714)
Portable air conditioner cold R290 Midea PD 3.5 kW (Reference 13907715)
Portable air conditioner cold/heat R290 Midea PD 3.5 kW (Reference 13907716)

Energy efficiency and performance

One of the most important aspects when choosing a climate control system is its ability to efficiently cool the space without skyrocketing energy consumption.

Fixed air conditioning (split)

They usually feature inverter technology, which adjusts the cooling power progressively, optimizing electrical consumption.
They offer higher energy efficiency compared to portable models, with ratings that can reach A++ or A+++.
They allow for uniform climate control in large rooms and maintain a constant temperature.
They tend to be quieter, as the compressor is located in an outdoor unit.

Portable air conditioning

Current models have significantly improved their efficiency, with energy ratings of class A.
They are ideal for air conditioning a single room or medium spaces, up to 30 m² depending on the power.
Although their performance is somewhat lower than that of a split, they offer a flexible and practical solution without the need for installation.

In terms of pure performance, a fixed air conditioner is more efficient and quieter, but a modern portable model like the Midea PD can be an excellent option for individual rooms without making a permanent installation.

Purchase and installation cost

The budget is a key factor in choosing the air conditioning system.

Portable air conditioning

Lower initial investment, with prices ranging between €300 and €800, depending on the power and features.
No professional installation required, you just need to plug it in and place the exhaust hose in a window.
No additional costs for labor or installation permits.

Fixed air conditioning (split)

Higher price, with costs that can exceed 1,000 € depending on capacity and energy efficiency.
Mandatory installation by a specialized technician, with an additional cost of 300 to 800 €, depending on the complexity.
May require permits or adjustments in rented buildings or homes.

Comfort and ease of use

The level of comfort offered by a climate control system depends on the noise level, air distribution, and mobility of the equipment.

Fixed air conditioning (split)

Less noise, as the compressor is outside (around 25-30 dB in low mode).
Uniform air distribution, as it is installed at height.
Does not take up floor space, allowing for a clearer environment.

Portable air conditioning

Easy mobility, can be moved from one room to another as needed.
Quick installation, without the need for construction work.
Adjustable operating modes, with night mode options to reduce noise (between 50-55 dB at maximum power).

The Midea PD models include silent mode and remote control, making them easy to use on a daily basis.

Maintenance and durability

Maintenance and the lifespan of the equipment are key aspects in the purchasing decision.

Fixed air conditioning (split)

Requires periodic professional maintenance to check the refrigerant gas, filters, and the outdoor unit.
Greater durability, with an estimated lifespan of 10 to 15 years.

Portable air conditioning

Simple maintenance, the user only needs to clean the filters and empty the condensation tank if necessary.
Lifespan of 8 to 10 years, depending on use and care.

If you prefer a low-maintenance system, portable air conditioning is the best option.

Environmental impact and refrigerant R290

The type of refrigerant gas is an important factor in the sustainability of the equipment. The use of R290 gas is an eco-friendly alternative with low environmental impact.

Low environmental impact, with a Global Warming Potential (GWP) of only 3, compared to other gases like R-410A (GWP of 2088).
Higher energy efficiency, which reduces electricity consumption.
Respects the ozone layer, as it contains no CFCs or HCFCs.

All Midea PD models use R290, standing out for their ecological commitment and energy efficiency.
