How to Choose the Right AC for Your 659 Sq Ft Home
Picking the perfect air conditioner isn’t just about BTUs. Here are a few more things to consider for your 659 sq ft space:
- Type of AC (Window vs. Portable):
- Window Units: Generally more efficient, quieter, and don’t take up floor space. Installation is permanent, and they block part of your window view.
- Portable Units: Offer flexibility to move between rooms, but are typically less efficient, a bit noisier, and require an exhaust hose vented through a window. They do take up floor space.
- Energy Efficiency: Look for ENERGY STAR certified units or those with inverter technology (like the LG DUAL Inverter or Midea U). Higher EER (Energy Efficiency Ratio) or SEER (Seasonal Energy Efficiency Ratio) ratings mean lower operating costs over time.
- Smart Features: Wi-Fi connectivity, app control, and voice assistant compatibility offer incredible convenience. You can turn your AC on before you get home or adjust settings from your sofa.
- Noise Level: Measured in decibels (dB), this is crucial, especially for bedrooms or living areas. Inverter technology often leads to quieter operation.
- Installation: Consider whether you’re comfortable with DIY installation or if you might need professional help. Ensure the unit fits your window type (single or double-hung).
- Additional Functions: Do you need a dehumidifier, a fan-only mode, or even a heating option for year-round comfort?
By weighing these factors, you’ll be better equipped to find the best air conditioner for house 659 sq feet that perfectly matches your specific needs and preferences.

FAQ Section
Q1: How many BTUs do I really need for a 659 sq ft house?
A1: Generally, a 659 sq ft house would require an air conditioner with approximately 12,000 to 14,000 BTUs. However, factors like ceiling height, insulation quality, sun exposure, and the number of windows can influence this. If your home has poor insulation or gets a lot of direct sun, you might lean towards the higher end of that range or even slightly above, like the 18,000 BTU LG unit, for faster cooling.
Q2: Are portable air conditioners as efficient as window units for a 659 sq ft space?
A2: Typically, window units are more energy-efficient than portable air conditioners. This is because window units exhaust heat directly outside, while portable units are inside the room and use an exhaust hose, which can sometimes allow some heat to seep back in. However, modern portable units with dual-hose systems or advanced features are closing this gap significantly, offering convenient cooling with decent efficiency.
Q3: What does “inverter technology” mean for an air conditioner?
A3: Inverter technology allows the AC compressor to operate at variable speeds rather than just turning on and off. This means the unit can precisely adjust its cooling output to match the room’s needs, leading to more consistent temperatures, quieter operation, and significantly higher energy efficiency compared to traditional single-speed compressors.
Q4: Can I install a window air conditioner myself?
A4: Many window air conditioners are designed for DIY installation with included EZ Mount or quick-snap brackets. However, it’s crucial to follow the manufacturer’s instructions carefully, ensure the unit is securely fitted, and that the window seals properly to prevent air leaks. Some larger units or those requiring special electrical outlets might be better handled by a professional.
Q5: What’s the benefit of a “smart” air conditioner with Wi-Fi control?
A5: A smart air conditioner with Wi-Fi control offers immense convenience. You can control it remotely from your smartphone using an app, allowing you to turn it on or off, adjust temperature, or set schedules before you arrive home. Many also integrate with voice assistants like Alexa or Google Assistant, offering hands-free control.
Q6: Should I consider an AC with a heating function for my 659 sq ft home?
A6: If you live in a region with fluctuating temperatures or want a versatile climate control solution, an AC with a heating function (like the LG 18,000 BTU combo unit) can be a great investment. It allows you to use the same unit for cooling in summer and supplemental heating in cooler seasons, potentially saving you from needing a separate heater.
Q7: How important is noise level (dB) when choosing an air conditioner?
A7: Noise level is very important, especially if the AC will be in a bedroom, living room, or home office. Decibel (dB) ratings indicate how loud a unit is. Generally, anything below 50 dB is considered quiet, and units like the Midea U at 32 dB or LG Inverter at 44 dB are exceptionally quiet, ensuring minimal disturbance to your daily activities or sleep.
