“We bought this for our camper to use as both a regular fan and a cooler.

Outside we will use it in our gazebo or under the awning with the cooling water/ice e”

“It’s super quiet, but also loud enough to satisfy my need for a running fan at night. It rotates, looks slick and is big but not in an obnoxious way. I really love that it has so many speed options, setting it on the lowest setting causes enough airflow that I can feel it just in front, and on its h”
“This is a great tower fan and it’s a replacement for an old LOUD oscillator fan that’s about to give out, at times it sounds like it wants to take flight.

“Update:I received a replacement, hoping that the first one was just not well crafted. Unfortunately, that is not the case.

Complete Buying Guide for Air Conditioners
Essential Factors We Consider
When choosing the best air conditioners, we evaluate cooling power (BTUs), room size compatibility, energy efficiency, noise level, installation requirements, and special features like timers, remotes, or dual-hose systems. We also consider real-world performance in different climates and user scenarios—whether you need windowless cooling, portability, or ultra-quiet operation for sleep.
Budget Planning
Air conditioners range from under $100 for basic evaporative coolers to over $500 for high-BTU portable units. Set a budget based on your needs: if you’re cooling a small space occasionally, a $150 tower fan or swamp cooler may suffice. For whole-room cooling in large areas, invest in a 10,000+ BTU portable AC with dual hoses. Remember to factor in long-term energy costs—look for Energy Star ratings to save on electricity.
Final Thoughts
The right air conditioner depends on your space, climate, and lifestyle. Windowless units offer flexibility, portable ACs deliver powerful cooling, and bladeless fans provide quiet comfort. Prioritize features that match your daily routine—like timers for overnight use or remotes for convenience. With our top picks, you’ll stay cool, save energy, and enjoy peace of mind all summer long.
Frequently Asked Questions
Q: What’s the difference between an evaporative cooler and a portable air conditioner?
A: Evaporative coolers (or swamp coolers) use water and airflow to cool and humidify air—ideal for dry climates. Portable ACs use refrigerant to actually lower air temperature and dehumidify, making them better for humid areas and larger spaces.
Q: Can I use a windowless air conditioner in any room?
A: Yes! Windowless units don’t require ventilation through a window, so they’re perfect for apartments, garages, sunrooms, or homes without traditional windows. Just ensure access to power and space for water refills.
Q: How do I calculate the right BTU size for my room?
A: As a rule of thumb, you need about 20 BTUs per square foot. A 300 sq ft room needs around 6,000 BTUs, while a 500 sq ft space requires 10,000–14,000 BTUs. Larger rooms or spaces with high ceilings may need more.
Q: Are portable air conditioners noisy?
A: Noise levels vary. Most modern portable ACs operate between 50–60 dBA—similar to a quiet conversation. Look for models with “quiet mode” or dual-hose designs, which tend to be quieter than single-hose units.
Q: Do I need to drain a portable air conditioner?
A: It depends. Some models have auto-drain or evaporation systems that eliminate manual draining. Others may require occasional emptying, especially in humid conditions. Check the product specs before buying.
