Frequently Asked Questions about Keystone Air Conditioners
Choosing an air conditioner can bring up a lot of questions. Here are some common queries about Keystone air conditioners to help you make an informed decision:
Q1: What does BTU mean, and how many BTUs do I need for my room?
A1: BTU stands for British Thermal Unit, which is a measure of thermal energy. For air conditioners, it indicates the unit’s cooling power. A general guideline is:
* 150 sq. ft.: 5,000-6,000 BTUs
* 250 sq. ft.: 6,000-8,000 BTUs
* 350 sq. ft.: 8,000-10,000 BTUs
* 550 sq. ft.: 12,000-14,000 BTUs
* 700 sq. ft.: 14,000+ BTUs
Consider factors like ceiling height, direct sunlight, and heat-generating appliances when calculating your exact needs.
Q2: Are Keystone window air conditioners easy to install?
A2: Most Keystone window air conditioner units come with a window installation kit and are designed for relatively straightforward DIY installation. You’ll typically need to secure the unit in the window opening, install side panels to seal the gap, and ensure it’s properly supported. For larger or heavier units, or wall-mounted models requiring specific electrical outlets, professional installation might be advisable.
Q3: What’s the difference between “cooling only” and “cooling with supplemental heat” models?
A3: A “cooling only” unit, as the name suggests, focuses solely on lowering the room temperature. “Cooling with supplemental heat” models provide both cooling and a heating function. The heating function is typically not meant as a primary heat source for an entire home, but rather to take the chill out of a room during mild to moderate cold weather, offering year-round comfort in that specific space.
Q4: How do the “Energy Saver” and “Sleep” modes work?
A4:
* Energy Saver Mode: This mode typically cycles the fan on and off with the compressor. When the compressor turns off after reaching the set temperature, the fan also turns off. The fan will periodically turn on to check the room temperature, and if it rises above the set point, the compressor kicks back in. This reduces energy consumption by not running the fan continuously.
* Sleep Mode: Designed for nighttime use, Sleep Mode gradually increases the set temperature by a few degrees over several hours, and often runs the fan at a lower speed. This saves energy while preventing the room from getting too cold during sleep, as the body’s temperature naturally drops overnight.
Q5: What is the “I Sense” or “Smart Remote Control” feature?
A5: Keystone’s “I Sense” or smart remote control is a really handy feature. The remote control itself has a temperature sensor built in. Instead of the AC unit sensing the temperature at its own location (which might be by a window), the remote takes the temperature of wherever you are in the room. It then sends this data to the AC unit, allowing the unit to cool or heat to your desired temperature more accurately in your immediate vicinity.
Q6: Are Keystone air conditioners generally quiet?
A6: Keystone offers several models, particularly their lower BTU window units, that are specifically designed for quiet operation, with noise levels as low as 49-52dB. This makes them excellent choices for bedrooms, nurseries, or home offices where noise can be a disturbance. While all ACs make some noise, Keystone strives to keep many of its units on the quieter side.
Conclusion
Whether you’re battling the summer heat or looking for a versatile unit that offers supplemental warmth, a Keystone window air conditioner provides reliable performance and thoughtful features designed for your comfort. From the super-quiet 5,000 BTU unit perfect for a cozy bedroom to the powerful 14,000 BTU wall-mounted system for larger living spaces, there’s a Keystone model engineered to meet diverse needs.
Remember to consider your room size, specific cooling/heating requirements, and energy efficiency features when making your choice. With any of these top picks, you’re not just buying an air conditioner; you’re investing in a more comfortable home environment. Stay cool, stay comfortable!
