Introduction: Why is it so important to calculate the right power?
One of the most common mistakes people make when buying an air conditioning unit in Torrevieja is not calculating the correct cooling power needed. This can lead to either oversizing (higher energy bills for no real benefit) or undersizing, which causes poor performance, uncomfortable temperatures, and premature equipment wear.
At AC Torrevieja, we take this issue seriously. That’s why we carry out personalised air conditioning studies based on the type of home, its location and your needs. The goal is simple: help you enjoy the perfect indoor temperature with minimum energy consumption.
How is the power calculated? Basic guideline
As a general reference, you can use a simple formula that ranges from 100 to 150 BTU/h per square metre, depending on various conditions:
- 100 BTU/h per m² for well-insulated spaces with limited sunlight exposure.
- 150 BTU/h per m² for poorly insulated or highly exposed areas.
📌 Example: a room of 20 m² would require between 2,000 and 3,000 BTU/h, which is about 2.5 kW of cooling capacity.
This is only a starting point. For real accuracy, we strongly recommend a professional assessment, especially in homes with unique conditions.
Key factors that influence power requirements
Not all homes are the same. Below are the main elements that affect the amount of cooling power you’ll need in Torrevieja:
- Orientation: South or southwest-facing homes receive more direct sunlight and require more cooling.
- Ceiling height: Rooms with high ceilings need more power as there’s more air volume to cool.
- Thermal insulation: Homes with double glazing and well-insulated walls need less power.
- Floor level: Top-floor flats (penthouses) are warmer, while ground floors tend to be cooler.
- Windows: More or larger windows mean more heat gain, especially if unshaded or west-facing.
Is more power always better? No, and here’s why
It’s a common myth that a more powerful unit is always the better choice. In fact:
- Oversized units consume more energy and cycle on/off frequently, which causes wear and inefficiency.
- They may cool the air too fast, failing to properly dehumidify, which can lead to discomfort.
The right-sized unit, however, will cool evenly, run efficiently, and maintain the ideal temperature for longer periods.
