Expert Tips to Save Money on Your Electricity Bill with Smart AC Usage

<>“Turning air conditioning units on and off multiple times daily can reduce electricity bills from CFE, according to recent expert analysis, while continuous operation significantly increases energy costs, according to multiple Mexican media outlets.

Experts cited in El Imparcial and Vanitatis warn that frequent cycling of air conditioning systems is more energy-efficient than leaving them running constantly, a practice that could lead to higher electricity expenditures. The advice aligns with findings from El Mundo, which states that an air conditioner can consume over 20 times more energy than a fan.

Manuel Amate, experto en ahorro energético, highlighted a common misconception: “Nos da algo” (translated as “It gives us something”), implying that users believe constant cooling provides continuous benefits despite the financial trade-offs.

The debate centers on how air conditioning systems interact with home cooling efficiency. Leaving units on constantly may cause them to work harder to maintain temperature, while intermittent use allows spaces to warm slightly before reactivation, reducing overall energy draw.

CFE, Mexico’s primary electricity provider, has not issued specific guidance on this practice, but industry analysts note that peak-hour energy rates and system efficiency play critical roles. A 2023 study by the Mexican Institute of Energy Efficiency found that homes using AC in short cycles saved on monthly bills compared to continuous operation.

Xataka, a tech and lifestyle publication, published a guide advising users to “cycle AC based on occupancy and ambient temperature,” emphasizing that modern systems are designed to handle frequent on-off cycles without mechanical strain. The outlet also recommended using smart thermostats to automate this process.

El Mundo’s report underscored the stark contrast between AC and alternative cooling methods. “An air conditioner can consume more than 20 times the energy of a fan,” the outlet stated, citing data from the National Energy Commission (CENACE). This disparity highlights the economic impact of choosing between high-consumption cooling systems and more efficient alternatives.

Energy experts caution that while cycling AC may lower bills, it requires careful management. “If the room heats up too much between cycles, the system will work harder to cool it, negating savings,” said a thermal engineering professor at the National Autonomous University of Mexico (UNAM), in an interview with El Periódico.

The advice also intersects with broader energy conservation efforts in Mexico. As CFE faces pressure to modernize its grid and reduce reliance on fossil fuels, consumer behavior plays a role in national energy strategies. A 2025 report by the Mexican Energy Research Institute noted that household AC usage accounts for a significant portion of national electricity demand during peak summer months.

For consumers, the key takeaway is balancing comfort with cost. “It’s about finding the right cycle frequency based on your home’s insulation and local climate,” said Amate, who recommended testing different schedules to optimize savings.

While the practice of turning AC on and off remains debated, the consensus among experts is clear: continuous operation is financially inefficient. As CFE continues to implement time-of-use pricing models, which charge higher rates during peak hours, strategic AC usage could become increasingly vital for budget-conscious households.

The advice also raises questions about the long-term sustainability of AC reliance. With climate change driving higher temperatures, the energy demand for cooling is expected to rise, potentially straining Mexico’s power infrastructure. Industry”
