The choice isn't about which is best—it's about what you want to pay for.
Com a chegada da Black Friday 2025, consumidores brasileiros se deparam com uma escolha que vai além do preço: o que, de fato, vale pagar por conforto térmico? Três modelos de ar-condicionado de 9.000 BTUs — Samsung, LG e Agratto — representam três filosofias distintas de consumo, do aparelho inteligente ao essencialmente funcional. Conhecer o histórico de preços e entender o que cada tecnologia oferece é o que transforma uma promoção em uma decisão consciente.
- A Black Friday pressiona consumidores a decidirem rapidamente, mas comprar por impulso pode significar pagar por recursos que jamais serão usados.
- O Samsung Digital Inverter Ultra Connect AI, atualmente em R$2.499, só justifica o investimento se cair para a faixa de R$2.000–2.100 — e raramente chega tão baixo.
- O LG Dual Inverter Voice tem mais margem de desconto e, abaixo de R$1.950, supera o Samsung em custo-benefício com recursos equivalentes.
- O Agratto Liv Top Inverter, sem Wi-Fi ou comandos de voz, entrega o essencial — eficiência energética — e abaixo de R$1.350 torna-se praticamente imbatível em valor.
- O histórico de seis meses revela os pisos reais de cada modelo, separando promoções genuínas de reduções cosméticas de preço.
A Black Friday 2025 coloca uma pergunta direta para quem pensa em comprar um ar-condicionado: quanto você deveria pagar? Para quem busca um modelo de 9.000 BTUs — ideal para quartos, escritórios ou ambientes de até 15 metros quadrados — a resposta depende do modelo escolhido e do quanto se está disposto a investir em recursos que talvez nunca sejam usados.
Três aparelhos dominam essa conversa. O Samsung Digital Inverter Ultra Connect AI, atualmente em torno de R$2.499, é o topo de linha: aprende hábitos, ajusta o consumo automaticamente e se conecta ao celular via Wi-Fi com inteligência artificial. Seu preço mínimo nos últimos seis meses foi R$2.299. Na Black Friday, um desconto real estaria na faixa de R$2.100; abaixo de R$2.000, a tecnologia embarcada justifica a compra. O problema é que, por ser premium, os varejistas raramente cortam seu preço de forma agressiva.
O LG Dual Inverter Voice disputa diretamente esse espaço, com preço atual de R$2.399 e mínima histórica de R$2.199. Seu diferencial está na eficiência: o compressor duplo garante operação silenciosa e economia real de energia, com classificação A. Também oferece compatibilidade com Google e Alexa. Na Black Friday, R$2.000 já seria competitivo; abaixo de R$1.950, ele se torna a escolha mais inteligente entre os dois.
Já o Agratto Liv Top Inverter representa uma filosofia diferente: sem Wi-Fi, sem comandos de voz, sem filtragem avançada. Apenas resfriamento eficiente. Atualmente em cerca de R$1.549, com mínima recente de R$1.499, é a porta de entrada para a tecnologia Inverter sem adicionais. Na Black Friday, R$1.400 já é um bom negócio; abaixo de R$1.350, torna-se quase impossível de superar em valor puro.
A escolha entre os três não é sobre qual é o melhor — é sobre o que você quer pagar. Samsung e LG atraem quem valoriza automação e controle remoto. O Agratto serve a quem quer apenas ar fresco e conta de luz menor. Os três usam tecnologia Inverter, que é o verdadeiro ganho de eficiência, independentemente da marca. O restante é o que você decide colocar em cima disso.
Black Friday 2025 arrives with a straightforward question for anyone thinking about buying an air conditioner: what should you actually pay? If you're shopping for a 9,000 BTU unit—the right size for a bedroom, office, or space up to about 15 square meters—the answer depends entirely on which model catches your eye and how much you're willing to spend on features you may never use.
Three machines dominate the conversation. The Samsung Digital Inverter Ultra Connect AI sits at the top of the market, currently priced around R$2,499. Over the past six months, it has dipped as low as R$2,299. This is the smart choice if you want a device that learns your habits, adjusts its energy use automatically, and connects to your phone. The Wi-Fi integration and artificial intelligence that powers it come at a premium. During Black Friday, a genuinely good deal would land somewhere near R$2,100. If it falls to R$2,000, the technology packed inside makes it worth the purchase. The catch: because it's a premium product, retailers rarely slash prices as aggressively as they do with simpler models.
The LG Dual Inverter Voice competes directly in this space, currently sitting at R$2,399 with a six-month low of R$2,199. LG's reputation rests on efficiency—the dual compressor design keeps the unit remarkably quiet while delivering serious energy savings, earning it an A-grade efficiency rating. Like the Samsung, it offers voice control compatibility with Google and Alexa, plus Wi-Fi. For Black Friday, a price around R$2,000 would be competitive. Below R$1,950, it becomes the smarter choice between the two, offering similar features at a lower cost.
Then there's the Agratto Liv Top Inverter, the third option and the one that strips away everything except what matters: cooling and savings. At roughly R$1,549 currently, with recent dips to R$1,499, it's the entry point to Inverter technology without the bells and whistles. No Wi-Fi. No voice commands. No advanced air filtration. Just a machine designed to cool your room and keep your electricity bill reasonable. During Black Friday, if it reaches R$1,400, you're looking at a solid deal. Anything below R$1,350 makes it nearly impossible to beat on pure value.
The choice between them isn't really about which is best—it's about what you want to pay for. The Samsung and LG both offer automation and control, features that appeal to people who like their homes to anticipate their needs. The Agratto appeals to someone with a simpler question: I need cool air, I want to save money, and I don't need my air conditioner to be smart. All three use Inverter technology, which is the real efficiency gain regardless of brand. The difference is what you're layering on top.
Price history matters here. Retailers track these units closely, and the numbers show patterns. The Samsung rarely drops below R$2,100 even on its best days. The LG has more room to move, especially when competing directly with Samsung. The Agratto, being the budget option, sees more volatile pricing but also more dramatic discounts. Black Friday will likely push all three toward their historical lows, but knowing where those lows sit—and what you're actually getting for the extra money—is what separates a good purchase from a regrettable one.

A Conversa do Hearth Outra perspectiva sobre a história
Why does a 9,000 BTU unit matter specifically? Why not go bigger or smaller?
Because it's the sweet spot. Anything smaller and you're undercooling a normal room. Anything bigger and you're wasting energy and money on capacity you don't need. Nine thousand BTUs handles a bedroom or office up to about 15 square meters without overkill.
So the Inverter technology—that's the real money-saver, not the brand?
Exactly. Inverter is the technology that matters for your electricity bill. The brand and model differences are mostly about what else they've added: Wi-Fi, voice control, fancy filters. Those are nice, but they don't cool better.
If I buy the Samsung at R$2,100 instead of the Agratto at R$1,350, what am I actually getting for that R$750 difference?
Automation. The Samsung learns when you're home, adjusts temperature on its own, lets you control it from your phone. The Agratto makes you walk to the unit and press buttons. If you like that convenience, it's worth it. If you just want cold air, it's not.
How confident should I be in these price targets you're mentioning?
They're based on six months of actual pricing data. These aren't guesses. The Samsung has never gone below R$2,299 in that window, so R$2,100 is realistic but not guaranteed. The Agratto has hit R$1,499, so R$1,400 is reasonable. But Black Friday is unpredictable—sometimes retailers go lower, sometimes they don't.
Should I wait for Black Friday or buy now?
If you need the air conditioner now, buy it. If you can wait, Black Friday will almost certainly be cheaper. These units always see discounts during the event. The question is whether the discount is worth the wait.
