Budget air conditioners priced at 4-5 million dong may not deliver electricity savings

From around 4 million dong, even lower during promotions, consumers can own an air conditioner. However, many people wonder: do cheap air conditioners actually save electricity? In electronics retailers, the cheap-air-conditioner segment is being offered at attractive prices ahead of the hot-season peak. Observations show that at around 4-5 million dong, customers can choose single-split models from familiar brands such as Funiki, Casper, or Sumikura. Products in this price range are mostly single-split units, 9,000 BTU, suitable for small rooms under 15 square meters. The main target audience for this segment is students, renters, or families needing rapid cooling at a low cost. Specifically, the Funiki model costs about 4-4.4 million dong, among the cheapest in the market. Meanwhile, Casper products typically range from 4.2-5.5 million dong. Sumikura air conditioners can dip to as low as about 3.9 million during promotions. According to surveys at electronics retailers, at 4.29 million dong, customers can buy a single-split Casper, actual cooling capacity about 8,900 BTU, non-inverter. At around 4.99 million dong, consumers have more choices with 9,000 BTU units from brands like Funiki, Hisense, or Sumikura. These products are all single-split, standard capacity for small rooms under 15m2. To keep prices low, manufacturers often cut inverter technology to optimize price, so energy savings are not a strong point. The electricity consumption of these models does not differ much, typically around 850-900 W during operation. Above 5 million dong, buyers can choose more models from brands like Midea, Nagakawa, Sunhouse, or AUX. These products in this price range begin to feature notable upgrades such as inverter technology to save electricity, quieter operation, and features like fast cooling (Turbo) or basic dust filtration. Do they save electricity? Mr. Nguyen Duc Khanh (air conditioner sales specialist) says that in the sub-5-million segment, models are considered "adequate." Most products do not come with inverter technology—an energy-saving factor. This means the machine may consume more electricity if used frequently. The input power of this group is typically around 0.85-0.9 kW during operation. Cooling performance of these models still meets basic needs in small spaces, cooling temperatures drop quickly after a few minutes of operation. However, quietness, temperature stability, and energy savings efficiency are not truly optimized. In some cases, user experience may be affected by noise or uneven cooling. Consumers who choose cheap air conditioners usually do not demand too high; they just need stable cooling for a few years. However, if used longer or to save electricity, they often switch to higher-end lines. Additionally, installation costs should be considered. In practice, buyers may pay extra from a few hundred thousand to more than 1 million dong for installation and accessories such as copper pipes and mounting brackets. According to experts, consumers should determine their needs before buying. For small rooms with a tight budget, air conditioners under 5 million are still a reasonable choice. If used frequently, to optimize long-term electricity costs and prioritize quiet operation, investing in inverter models yields better results. In the context of rising electricity prices and increased usage, consumers should weigh carefully the "cheap now – costly later" math. Duy Anh (Source: VietNamNet)
