With warmer days on the horizon, many households are already planning to install an air conditioner to avoid restless summer nights spent sweating through heat.

Questions naturally arise: which air conditioner should be chosen, what will installation cost, and how much energy does it consume? Will it noticeably affect the electricity bill?

This content begins by addressing a crucial point experts emphasize: selecting the right type of air conditioner matters a lot.

Thanks to ongoing developments from leading brands, new models now use far less energy. Inverter technology and energy-efficient designs from top manufacturers have introduced equipment that helps cut electricity costs over time.

To help clarify, experts from Grupo Aplus address common questions: air conditioning systems do consume energy, but with inverter technology that consumption decreases over time as the unit runs longer and approaches the target temperature. If the unit is used correctly and is rated A energy efficiency or higher, bills won’t spike dramatically, explains Iván Bordonado, an energy consultant specializing in air conditioning at Grupo Aplus.

Grupo Aplus brings extensive industry experience in air conditioning installation, solar energy, and ducted systems. A large, professional team stands ready to tailor solutions for every project.

One of the company’s strengths is its capacity to guide customers through the entire process—from choosing the right system to ensuring optimal performance and energy savings.

What type of air conditioner should be chosen?

One of the first questions in the installation journey is: which type of air conditioner fits best? Grupo Aplus professionals typically categorize units into three families: wall-mounted split systems, ducted (central) systems, and cassette units. Each type aligns with different installation conditions and needs.

If cooling a single room is the goal, a wall-mounted split system is ideal. For whole-house cooling, a central ducted system is usually the best option. For commercial spaces or rooms with high ceilings, a cassette system can be the right choice. A specialist should help determine the best fit.

Another key aspect is selecting a unit with appropriate capacity to avoid excessive energy use. Choosing a system that is too powerful or too weak can cause high peak consumption as the unit operates at full capacity, which raises costs. The right choice depends on the space and usage patterns.

Grupo Aplus notes that an efficient unit with inverter technology and a suitable power rating makes a big difference in monthly energy costs. A converter-driven compressor speed control keeps operation steady and avoids power peaks that drive up the bill.

Energy efficiency labels also matter. An A+ or higher rating typically yields noticeable savings compared with machines lacking this certification.

For example, a wall-mounted unit with around 3,000 refrigeration units might serve a 20 to 25 square meter area, costing roughly €1.50 per day at eight hours of use, about €45 per month. A ducted system designed for roughly 90 square meters may consume closer to €120 per month, illustrating how size and usage affect costs. In this context, a Grupo Aplus energy consultant emphasizes maintaining comfort while budgeting for the whole home.

How many heating and cooling units are needed for a good setup?

Before calculations begin, it helps to understand a cooling unit’s power rating. This measurement indicates how much heat the system can absorb per hour and is a key factor in sizing.

The general rule of thumb is to estimate cooling needs based on space, climate, sun exposure, and building materials. Typical guidelines suggest certain refrigeration capacities per square meter, with examples for different home sizes.

The ideal indoor temperature for both health and savings typically falls between 24°C and 26°C. Each degree cooler can raise energy use by a notable margin, so selecting efficient systems with varied operating modes is advisable.

Adjusting temperature properly benefits well-being and reduces costs.

Overall, frequent maintenance and thoughtful system selection contribute to reliable comfort and ongoing energy savings across the home.

In summary, choosing the right air conditioner involves matching the system type to the space, sizing it accurately, and prioritizing inverter efficiency and energy labeling to keep monthly bills reasonable while maintaining comfort.
