With warmer days ahead, many households start planning ahead to avoid another sleepless summer caused by heat. Installing an air conditioner at home becomes a practical solution to maintain comfort when temperatures rise.
Questions naturally arise: which air conditioner is right for a space? How much does installation cost? What impact does it have on electricity consumption and the monthly bill?
From the outset, experts emphasize a clear approach and offer guidance on selecting the suitable unit. Advancements from leading brands have reduced energy use. Inverter technology and ongoing energy-efficiency improvements have produced equipment that helps lower electricity costs while keeping rooms comfortably cooled.
Experts from Grupo Aplus address common concerns: air conditioning units consume energy to operate, which increases home electricity use. Yet with inverter technology, the overall consumption decreases as the device runs longer and maintains the desired temperature with less wasteful cycling. When operated correctly and paired with an A-grade or higher efficiency rating, bills are kept reasonably low, according to Iván Bordonado, an energy consultant specializing in air conditioning at Grupo Aplus.
Grupo Aplus prides itself on a broad, professional team ready to tailor solutions for every need and project in air conditioning, solar energy, and ducted systems.
Which air conditioner should be chosen?
A common first question when planning an installation is: what type of air conditioner is best? Grupo Aplus professionals note three primary families: wall-mounted split systems, ducted central systems, and cassette units. Each type fits different installation requirements and spaces.
For cooling a single room, a wall-mounted split unit is ideal. For whole-home cooling, a ducted system is typically preferred. For commercial spaces or areas with high ceilings, cassette units may be the best fit. A specialist should assess needs and recommend the most appropriate option.
Another key consideration is selecting a unit with appropriate power to avoid a high initial surge that forces the machine to run at maximum capacity. The goal is steady operation that aligns with the space and usage, notes Iván Bordonado. Matching air conditioner capacity to the surface area is crucial to ensure efficient cooling without excessive consumption.
Here, a capable partner helps determine the right unit based on the room size, insulation, and sun exposure. A high-quality unit withconverter technology can regulate compressor speed, smoothing energy use and preventing peak demands that drive up costs.
The energy certificate matters, too. An A+ or higher rating contributes to meaningful savings over time. When a system earns a strong efficiency label, it typically outperforms models without such certification, helping households reduce monthly expenses.
For context, a wall-mounted unit rated around 3,000 refrigeration units (suitable for roughly 20–25 square meters) might consume about 0.9 kW, translating to roughly €1.50 per day if used eight hours daily, or about €45 per month. A ducted system serving a larger space of around 90 square meters can require around 8,000 refrigeration units and consume nearly 2.8 kW, equating to about €4 daily or roughly €120 per month in the same usage pattern. A qualified energy consultant from Grupo Aplus confirms heat in a home remains manageable with consistent, well-planned operation.
How many refrigeration units are needed for effective air conditioning?
Before calculating, it helps to understand refrigeration units, a measure of cooling power. Equivalent to the amount of heat the system can absorb per hour, refrigeration units indicate how much cooling capacity a unit provides.
Every space varies, so many factors come into play when sizing the system, including climate, sunlight, building materials, and insulation. As a general guideline, cooling capacity often scales with area, though precise requirements depend on the specifics of the home or business.
The rough rule of thumb is about 100 refrigeration units per square meter, with typical recommendations such as 4,000 for 25–50 m², 6,000 for 50–70 m², 8,000 for 80–100 m², 10,000 for 100–120 m², and so on. Smaller rooms in the 5–15 m² range may need around 2,000 refrigeration units, with incremental increases for larger spaces. A professional assessment helps tailor exact figures to the site.
What is the recommended temperature for cooling?
The target range for comfort and savings is typically between 24ºC and 26ºC. Lowering the temperature by each degree can raise energy consumption by roughly 8 percent, depending on the system and usage. To maximize efficiency, choose an air conditioner with high energy performance and operate in modes designed for energy savings while preserving comfortable temperatures.
Balancing temperature with efficient operation reduces electricity use while maintaining healthful, comfortable environments. Properly adjusting settings and using efficient models leads to measurable savings over time.
Everyone’s home is different. Factors such as window placement, insulation quality, and climate influence cooling needs. The goal is steady, efficient cooling rather than chasing the coldest possible air.
