Let’s be real for a second. If you’re scouring the internet for a portable air conditioner under $150, you’ve probably already seen those sleek, palm-sized cubes that claim to "freeze your room in seconds" for thirty bucks.
They’re lying.
Mostly. Those tiny boxes aren't air conditioners; they’re evaporative coolers (swamp coolers), and if you live in a humid place like Florida or Houston, they’ll basically just turn your bedroom into a tropical rainforest without actually dropping the temperature. Finding a legitimate, compressor-based unit that actually vents hot air out a window for less than 150 bucks is like hunting for a unicorn in a basement. It's hard. But it’s not impossible if you know where the industry hides the deals and which "cooling" tech is actually worth your cash.
Most people get burned because they don't understand the difference between chilling the air and just moving it. A real AC uses a refrigerant cycle. It's heavy. It’s loud. It’s usually expensive. To get one under this price point, you have to be willing to look at refurbished models, end-of-season clearances, or very specific "personal" AC units that bridge the gap between a fan and a window unit.
The Brutal Truth About the $150 Price Point
Here is the thing. The manufacturing cost of a compressor, the copper coils, and the R32 refrigerant alone makes it incredibly difficult for brands like Black+Decker, Whynter, or LG to sell a brand-new, full-sized floor unit for $150. You'll usually see those start at $280 and go up. So, when you see a portable air conditioner under $150, you are looking at one of three things: a "Personal" AC, a refurbished unit, or a "Mistake."
By mistake, I mean the misleading marketing that plagues Amazon and TikTok. These companies list "Portable AC" in the title, but when you scroll down to the fine print, it says "Evaporative Air Cooler." If you don't have a window to vent out of, you aren't buying an air conditioner. You're buying a fancy humidifier.
If you actually want to lower the room temperature by 10 or 15 degrees, you need BTUs. Specifically, you’re looking for units in the 5,000 to 8,000 BTU range. In the current market, finding these brand new for under $150 is rare, but I've seen the Midea EasyCool or smaller Arctic King models hit this price point during Black Friday or early March clearances. Honestly, if you see a real compressor-based floor unit for $149, buy it immediately. Don't think. Just click.
Why Refurbished is Your Best Friend
If you’re dead set on a portable air conditioner under $150, stop looking at "New" listings.
Go to VIPOUTLET or the official eBay refurbished stores for brands like Toshiba or Honeywell. These are often units that someone bought, realized was too loud for their office, and sent back. They get inspected, certified, and then dumped for 40% off. This is the "pro move." You can often snag a $300 unit for $140. It might have a scratch on the plastic. Who cares? It’s 95 degrees outside. You need cold air, not a trophy.
Understanding BTUs Without the Science Lecture
BTU stands for British Thermal Unit. Basically, it’s a measure of how much heat the machine can rip out of the room.
The Department of Energy (DOE) changed how they rate these things a few years ago because the old ratings were, frankly, optimistic. A unit labeled "8,000 BTU" under the old ASHRAE standard might only be "5,000 BTU" under the new SACC (Seasonally Adjusted Cooling Capacity) rules.
When shopping for a portable air conditioner under $150, you'll likely be looking at the lower end of this scale. A 5,000 BTU (SACC) unit is perfect for a small home office or a tiny bedroom—roughly 150 to 250 square feet. If you try to put a $150 unit in a vaulted-ceiling living room, you’re just wasting electricity. It’ll run 24/7, get the air slightly less swampy, and your power bill will make you cry.
The Personal AC Loophole
There is a sub-category of "Desktop" ACs that actually use a tiny compressor. Brands like Evapolar (the high-end ones) or certain NewAir personal units sometimes dip near the $150 mark. Unlike the "water-fan" scams, these have a small cooling element.
The catch? They only cool the "zone" directly in front of you.
Think of it like a spotlight of cold. Great if you’re gaming or sleeping alone. Terrible if you want the whole room to feel crisp. If you see a unit that uses a power brick instead of a thick 3-prong grounded plug, it's probably not powerful enough to cool a whole room. Always look at the wattage. A real AC pulls a lot of juice.

What to Look for (And What to Avoid)
Let's talk specs. You want a unit with a washable filter. In this price bracket, companies love to save money by making you buy proprietary filters every month. Don't fall for it. You want to be able to slide that mesh out, rinse it in the sink, and slap it back in.
Also, check the drainage situation.
Cheap portable air conditioners often don't have "auto-evaporation" technology. In expensive units, the moisture they pull from the air is splashed onto the hot condenser coils and turned into vapor, which then goes out the window hose. In a budget portable air conditioner under $150, you might have to manually empty a water tank every 4 to 6 hours. If you forget, the machine shuts off. There is nothing worse than waking up at 3 AM in a pool of sweat because your AC's "bucket full" light came on.
- Window Kit Inclusion: Make sure the box actually includes the plastic slider for the window. Some "cheap" units sell this separately, which is a total scam.
- Noise Levels: Budget units are loud. We're talking 55-65 decibels. It sounds like a plane taking off in your closet. If you're a light sleeper, this is a dealbreaker.
- Hose Length: Most hoses are 5 feet. If your window is high up or you want the unit far from the wall, you're out of luck.
The "Used" Market Reality
Honestly, the best portable air conditioner under $150 is usually a $400 unit that someone is selling on Facebook Marketplace because they just moved into a place with central air.
I've seen De'Longhi Pinguino units—which are the gold standard—go for $120 in September. If you can wait until the "shoulder seasons" (Spring or Fall), your $150 goes twice as far. If you buy in the middle of a July heatwave, you're going to pay a "desperation tax."
When buying used, always ask the seller to run it for 10 minutes before you show up. Feel the air coming out of the vent. It shouldn't just be "cool"; it should be cold. Like, "hurts your hand after a minute" cold. If it smells like vinegar or mold, walk away. That unit has "dirty sock syndrome," and you'll never get that smell out of your carpet.

Setting Realistic Expectations
You aren't getting a smart-home integrated, whisper-quiet, dual-hose masterpiece for 150 bucks.
You’re getting a loud, heavy box that makes a specific area of your home habitable. And that’s okay! Sometimes you just need to survive a heatwave without your laptop melting. Just be prepared for the limitations. Most units in this price range are "single hose." This means they create negative pressure in the room, pulling in warm air from under the door or through cracks in the window to replace the air they’re blowing outside. It's inefficient, but for $150, it beats a box fan and a prayer.
Actionable Steps for the Budget Hunter
If you need to cool down right now and $150 is your hard ceiling, here is your roadmap.
First, check the Walmart "Rollback" section or the Home Depot "Special Buy" page. Specifically look for the brand Costway or Midea. They often have 5,000 BTU window units (which are better than portable ones anyway) for $139. If it must be portable because your HOA hates window units, look for the Black+Decker 5,000 BTU (SACC) refurbished units on Amazon.
Second, avoid anything that says "Arctic," "Chill," or "Frost" if it only plugs into a USB port. Those are fans. They will not lower your room temperature. Period.
Third, measure your window before you buy. Most portable AC kits are designed for vertical or horizontal sliders. If you have "crank-out" (casement) windows, you’ll need to buy a special fabric seal for an extra $25, which might push you over your $150 budget.
Finally, keep your receipt. Budget ACs have a higher failure rate than the premium ones. If the compressor doesn't kick on after two days, you want to be able to drop that 50-pound box back at the customer service desk without a headache.
Go for the refurbished name-brand over the "No-Name" new unit every single time. Your future, non-sweaty self will thank you.
