My landlord banned window units and I'd been sweating through every summer for three years. This cooled my apartment from 82°F to 68°F and I slept through the whole night for the first time since June. No window. No drama. No landlord involved.

My home office hits 90°F by noon in summer. I was visibly sweating on Zoom calls — not exactly professional. This runs quiet enough that nobody on the call can hear it and keeps me completely comfortable. I set it before meetings and it's cold before I'm even on camera.

At 68 I can't lift a window unit anymore and didn't want to ask my son every summer. This rolls right where I need it on its wheels, fills up in minutes, and actually cools the room. My sunroom is finally comfortable year-round. Best gift I've given myself in years.

"I actually cried. I forgot what cool air felt like."
"Three summers of sleepless nights in my Brooklyn apartment. My landlord wouldn't budge on window units. I ordered this on a Thursday. By Friday night my bedroom was 68°F. I sat on my bed and cried. I'd forgotten what sleeping cool felt like."
New York, NY
"My landlord has been in my apartment twice. Never even noticed it."
"He sent me a formal lease violation over my window unit last summer. I spent the whole season miserable with box fans. This just sits there. No window mod, no installation, nothing for him to complain about. I finally have my apartment back."
Los Angeles, CA
"My electric bill dropped from $410 to $195. Same month. Same heat."
"I'm a numbers person. July: $410 with central AC running all day. August: $195 using this in the rooms we're actually in. Same house, same family of four, same brutal summer. This pays for itself in about three weeks. The math doesn't lie."

Replaced my window AC AND my space heater. One unit. Done.
I live in a studio apartment in Chicago. Brutal summers, brutal winters. I had a window AC my landlord kept threatening to make me remove, and a cheap space heater that tripped the breaker constantly. Bought this to replace both. Plugged it in. Switched to cool mode in summer and heat mode in winter. My landlord has never said a word about it because there is nothing to say — it just sits there. No window installation. No hoses. Nothing. I have not had a single issue in 14 months. This is the most useful appliance I have ever owned. Period.

UPDATE: Used it through a full year. Summer AND winter. Still perfect.
Summer review (August): Cooling mode blows genuinely cold air right where I sleep — the air coming out of the vent is easily 10-15°F cooler than the room, especially with the ice crystal boxes frozen and in the tank. No window needed. No landlord drama. Winter update (January): Switched to heat mode for the first time last week. Low heat is perfect for taking the chill off my bedroom without running the central heat all night. 2000W high heat warms the room fast. One year in. Both modes still work exactly as they did on day one. The evaporative cooler and PTC heater just keep running with no maintenance headaches. I cannot recommend this enough for anyone who rents.

HVAC contractor for 22 years - the heating function genuinely surprised me
I install and service HVAC systems for a living. I bought this for my rental property tenant who couldn't have window units, fully expecting to be unimpressed. The cooling works as advertised — it's a proper evaporative cooler with a 7L tank and two water-fillable ice boxes, and the air coming off the vent is genuinely cold when the ice boxes are frozen and dropped in. Consistent output for hours. That part I expected. What surprised me was the heat function. The 2000W PTC ceramic heater is legitimate warmth for a closed bedroom or office — not the weak trickle you get from most portable units. Three fan modes mean you can run it quietly overnight on sleep wind in cooling season. I've now recommended this to four clients. That should tell you everything.

My landlord threatened eviction over my window unit. This saved me — in two seasons.
Last summer my landlord sent me a formal lease violation over my window AC. Eviction threat. In a heat wave. In Phoenix. I found this, bought it immediately, and never looked back. No window modification, nothing for him to complain about. He's been in my apartment three times since and never said a word. Then Arizona winter hit and my apartment got genuinely cold at night. I switched to heat mode. Same unit, same outlet, completely different season. I have not bought a separate heater. I have not argued with my landlord. I have slept comfortably every single night for over a year. This is the product I wish I had found three years ago.

I tested both modes with a thermometer. Here are the real numbers.
Engineer brain — I measured everything. Cooling mode in my 280 sq ft bedroom (thermometer clipped 3 ft in front of the vent): - Room air: 83.4°F - Air coming out of the vent (water only): about 76°F - Air coming out of the vent (with both ice crystal boxes frozen and dropped in the tank): about 68°F - 10-15°F cooler air right where I'm sitting, all day, without a hose Heating mode same room in January: - Starting room temp: 58°F (cold night, radiator off) - After 20 minutes on high heat: 68°F - After 40 minutes: 72°F - Steady state: 73-74°F (2000W PTC ceramic is real heat) Energy cost on cooling: pennies — 75W is a rounding error on my bill. Heat on high (2000W) obviously costs more, but heating just my bedroom is still way cheaper than running central heat all night. The data is clean. This unit does exactly what an evaporative cooler + ceramic heater says it will.

My wife has MS. Heat and cold both trigger her. This gave her every season back.
My wife's MS is triggered by both heat and cold. Summer heat causes numbness and brain fog. Winter cold causes muscle spasms. We live in a condo that doesn't let us install window units or portable heaters above a certain wattage. We put one of these in every room she uses. In summer it cools. In winter it provides gentle warmth on low heat without triggering the HOA rules. Each room stays in the narrow comfort range her neurologist recommends year-round. Last month she hosted her book club for the first time in two years. She couldn't have done that before. I don't care what this cost. Worth everything.

Sign In to ContinueCorrect — no window, no hose, no installation required for either mode. ClimaFlow is genuinely two products in one appliance:
In cooling mode it's an evaporative cooler. You fill the 7L water tank, and the built-in fan pulls room air through a water-saturated cooling pad. The air comes out of the vent 10-15°F cooler than the room. For the coldest possible air, you fill the two included ice crystal boxes with water, freeze them, and drop them into the tank alongside the water. This is zone cooling — the air blowing at you and the space right around the unit — not whole-house refrigeration.
In heating mode it switches to a 2000W PTC ceramic heater built into the same unit. The WARM button cycles low heat → high heat → off. That's real, room-warming heat for a bedroom or office, not a weak trickle.
One outlet, two seasons, zero modifications to your apartment.
Fair concern — and we hear it constantly. Most products marketed as personal ACs on social media are basically desk fans with a fancy shell — they barely move the needle. ClimaFlow is a genuine evaporative cooler with a 7L water tank, a real wet-pad cooling stage, and two water-fillable ice crystal boxes you freeze and drop into the tank for the coldest possible air. The air coming out of the vent runs 10-15°F cooler than the room — real customers have measured it with thermometers.
Honest expectation-setting: this is zone cooling, not central AC. It cools the air blowing at you and the space right around the unit (roughly 6-10 ft). If you want fixed-thermostat whole-room refrigeration, that requires a refrigerant unit with a window hose — a different product entirely. If ClimaFlow doesn't cool your space the way we describe, Breeze AC's 30-Day Guarantee covers you completely.
Yes — genuinely. ClimaFlow has a built-in 2000W PTC ceramic heater. The WARM button cycles low heat → high heat → off, so you can dial it in for the room and the weather.
On low heat it takes the chill off a bedroom or office and maintains a comfortable temperature overnight. On high heat (the full 2000W) it warms a closed room significantly faster — customers report going from 58°F to 72°F in under 40 minutes. It's not a replacement for whole-home central heating, but for the room you're actually sleeping or working in, it delivers real, consistent warmth. Recommended on a 15A+ circuit so it doesn't share a breaker with other high-draw appliances.
Maintenance is genuinely simple — no cartridges to buy, no replacement filters, no special tools required. Once every 1-2 weeks: rinse the air filter screen with clean water, empty and rinse the 7L water tank, and give the wet cooling pad a quick freshwater rinse. For the ice crystal boxes, just refill with clean water and refreeze — they last indefinitely. Before you store the unit at the end of cooling season, empty and dry both the tank and the ice boxes so nothing sits wet.
That's the entire upkeep. If any issue does come up, Breeze AC's 30-Day Guarantee and our US-based support team are here to help.
Sleep Mode was built for exactly this. In Sleep Mode the ClimaFlow runs at its quietest in both cooling and heating functions — gentle, consistent airflow with no cycling noise that wakes you up. We have reviews from night-shift nurses, CPAP users, new parents, and light sleepers who run it every single night in both seasons. If noise has killed other units for you before, Sleep Mode on this one is a genuinely different experience.
Yes — no installation needed. The ClimaFlow plugs into any standard 120V outlet, so as long as you have shore power, a generator, or a compatible inverter setup, you're good to go. Its compact form factor fits easily in tight RV and trailer spaces, and it's simple to store between trips. Van-lifers, weekend campers, and full-time RVers have all left positive reviews.
