Mexico updates air conditioning energy efficiency standards

Time：

2025-08-25

Mexico has officially released the NOM-011-ENER-2024 standard, which sets new energy efficiency requirements for central, integral, and split air conditioners.

The Mexican government recently officially released the NOM-011-ENER-2024 standard, which sets new energy efficiency requirements for central, integral, and split air conditioners. This standard will officially come into effect on the 180th calendar day after October 26, 2025, replacing the NOM-011-ENER-2006 standard that has been in effect for nearly 20 years, marking an important step for Mexico in promoting energy conservation, emission reduction, and green cooling.

The new standard was developed by the Mexican National Commission on Energy Efficiency (CONUEE), which specifies the minimum Seasonal Efficiency Ratio (SEER) that central air conditioners must meet, and clarifies the testing methods and public information labeling requirements required to verify compliance. This standard applies to electrically driven ducted central air conditioners, integral and split air conditioners, with a cooling capacity range of 5275 watts to 19050 watts, including mechanical compression systems and single speed and variable frequency systems equipped with air-cooled evaporator coils and air-cooled condenser coils.

01. Energy Efficiency Status in Mexico

The energy consumption of air conditioning in Mexico is mainly concentrated in the hottest four months of the year, accounting for 10% of the country's total electricity consumption. In the context of addressing climate change and energy security challenges, Mexico has established a comprehensive HVAC regulatory system, including Mexico's official standards (NOM), energy efficiency policies from the Ministry of Energy (SENER), and best practice guidance from the National Commission on Energy Efficiency (CONUEE).

At present, the demand for energy-efficient air conditioning in Mexico is rapidly growing, and the government's energy efficiency certification program, labeling system, incentives for energy-efficient air conditioning, and ban on HCFCs refrigerants have all had a positive impact on the market. Meanwhile, the introduction of intelligent air conditioning technology has further improved the energy efficiency level of the air conditioning system.

The greenhouse gas emissions caused by air conditioning account for about 3% of global emissions, and with global warming and income growth, the demand for refrigeration is expected to triple by 2050. In 2024, the global room air conditioner market will grow by 4% to 140.58 million units, with the Latin American market experiencing growth driven by Brazil, Mexico, and Argentina, accounting for 77% of the total sales in the region.

Industry experts believe that stricter energy efficiency standards will drive manufacturers to increase their investment in technological innovation, promote the popularity of high-efficiency and energy-saving air conditioning products, bring lower operating costs to consumers, and help Mexico achieve its carbon reduction goals.
