“Very happy with this purchase. Placed it in the apartment above our garage in the existing opening after removing the old unit. It worked for fit and the cord is more than long enough to reach the plug. The fellows who did the install did a really nice job. Keeps the room very cool and comfortable.”
“I had the same experience as Matt Punk. Sadly, I bought the unit over Memorial Day and didn’t use it for weeks because it wasn’t warm enough so I didn’t notice the design flaw until it got into the 90’s with high humidity. Now my return window has expired. It overheats and shuts down with the error code.”

Complete Buying Guide for Best Air Conditioner for 700 Square Feet
Essential Factors We Consider
When selecting the best air conditioner for 700 square feet, we evaluate BTU capacity, energy efficiency, noise level, ease of installation, and smart features. A 14,000 BTU unit is typically ideal for this size, but insulation, ceiling height, and sun exposure also matter. We prioritize models with remote controls, multiple fan speeds, and reliable brand support. Durability and warranty are also key—nobody wants an AC that fails after one season.
Budget Planning
Prices for 700 sq ft air conditioners range from around $300 to $600. Budget models like the Black+Decker 12,000 BTU offer great value, while smart units like the GE Wi-Fi AC come at a premium. Consider long-term energy savings: ENERGY STAR-certified models may cost more upfront but reduce electricity bills over time. Always factor in installation—window units are DIY-friendly, but through-the-wall models may require professional help.
Final Thoughts
Choosing the right air conditioner for 700 square feet means balancing power, price, and features. Whether you need basic cooling, smart controls, or dual heating functionality, there’s a model on this list that fits your lifestyle. Don’t overlook customer reviews and warranty coverage—they often reveal real-world performance beyond the specs.
Frequently Asked Questions
Q: What size air conditioner do I need for 700 square feet?
A: A 14,000 BTU air conditioner is generally recommended for rooms up to 700 square feet. However, if the space gets a lot of direct sunlight or has high ceilings, consider a slightly higher capacity or ensure the unit has strong airflow and multiple fan speeds.
Q: Can a 12,000 BTU AC cool 700 square feet?
A: It can, but only if the room is well-insulated and not overly exposed to heat. For optimal performance, a 12,000 BTU unit is better suited for spaces up to 550–600 sq ft. For full 700 sq ft coverage, 14,000 BTU is safer.
Q: Are window or through-the-wall ACs better for large rooms?
A: Both can work well. Window units are easier to install and remove, making them ideal for renters. Through-the-wall models offer a cleaner, permanent solution and don’t block natural light, but require more complex installation.
Q: Do smart air conditioners save money?
A: Yes, if used wisely. Smart ACs let you schedule cooling, monitor usage, and adjust settings remotely, which can reduce energy waste. Over time, this leads to lower electricity bills, especially in hot climates.
Q: How loud are these air conditioners?
A: Most modern units operate between 50–60 dB—comparable to a quiet conversation. Look for models with “low noise” or “quiet mode” features if you’re sensitive to sound, especially for bedroom use.
