Question

What size window air conditioner unit and brand should I have if I live in the heat of Texas and where the sun beats down in the windows are very poor? I want it to be around 60 to 63 every night because I have a medical condition.

Answer 1

To effectively cool a room in the heat of Texas and maintain a temperature range of 60 to 63 degrees Fahrenheit, you'll need a properly sized air conditioner unit from a reliable brand. Here are some considerations to help you make an informed choice:

1. Cooling Capacity: The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs). To determine the appropriate size for your room, you'll need to calculate the square footage. Measure the length and width of the room, multiply these values, and use the following as a general guideline:

   • 100 to 150 square feet: 5,000 to 6,000 BTUs
   • 150 to 250 square feet: 6,000 to 8,000 BTUs
   • 250 to 300 square feet: 8,000 to 10,000 BTUs
   • 300 to 400 square feet: 10,000 to 12,000 BTUs
   • 400 to 450 square feet: 12,000 to 14,000 BTUs
   • 450 to 550 square feet: 14,000 to 18,000 BTUs

   Keep in mind that these are general estimates, and factors like insulation, ceiling height, number of windows, and sun exposure can affect the cooling load. For Texas heat, it's better to err on the higher side of the BTU range.

2. Energy Efficiency: Look for air conditioners with high Energy Efficiency Ratio (EER) ratings. Higher EER ratings indicate more efficient cooling, which can save you money on electricity bills. ENERGY STAR-certified units are an excellent choice as they meet stringent energy efficiency guidelines.

3. Brand and Quality: Opt for reputable brands known for producing reliable and durable air conditioners. Some popular brands include LG, Frigidaire, GE, Haier, and Friedrich. Research customer reviews and consider warranties and after-sales support when making your decision.

4. Additional Features: Consider features such as adjustable fan speeds, programmable timers, remote control, sleep mode, and air purifiers. These features can enhance your comfort and convenience.

Remember, installing the air conditioner properly and sealing any gaps around the windows will help maximize its cooling efficiency.

Lastly, consult with a professional HVAC technician to assess your specific requirements and ensure you choose the most suitable air conditioner for your medical condition and desired temperature range.
