Frequently Asked Questions (FAQs)
Q1: What room size is a 12,000 BTU air conditioner suitable for?
A1: A 12,000 BTU air conditioner is generally ideal for cooling rooms that are between 450 to 550 square feet. This makes them suitable for large bedrooms, living rooms, studio apartments, or small offices.
Q2: What’s the main difference between a window and a wall-mounted AC unit?
A2: A window AC unit installs directly into an open window, often obstructing a portion of the view. A wall-mounted AC unit requires a hole in the exterior wall for installation, preserving your window view and maximizing floor space, but typically involves a more complex installation process.
Q3: Do all Keystone 12,000 BTU units come with heating capabilities?
A3: No, not all of them do. Some Keystone 12,000 BTU models offer supplemental heating, while others are designed purely for cooling and dehumidification. Always check the product features to confirm if heating is included.
Q4: Are Keystone air conditioners energy efficient?
A4: Many Keystone models are designed with energy efficiency in mind, featuring modes like ‘Energy Saver’ and ‘Sleep’ to reduce power consumption. Some high-end models even include Inverter Technology for superior efficiency and an Energy Star rating, indicating they meet strict energy performance standards.
Q5: What is ‘I Sense’ remote technology and how does it work?
A5: ‘I Sense’ remote technology means the remote control itself has a temperature sensor. It takes readings from your immediate vicinity and sends them to the AC unit, allowing the unit to adjust its output to ensure the temperature around you (where the remote is) is exactly what you desire, rather than just the temperature at the unit itself.
Q6: How often should I clean the filter on my Keystone AC unit?
A6: For optimal performance and air quality, it’s generally recommended to clean your AC filter every 2-4 weeks during periods of heavy use. Some Keystone units even have a “clean filter” alert to remind you. A clean filter ensures efficient operation and extends the life of your unit.
Q7: Can I install a wall-mounted Keystone AC unit myself?
A7: While some DIY-savvy individuals might attempt it, installing a wall-mounted AC unit typically requires cutting a specific size hole in the wall and may involve specialized electrical wiring (especially for 230V units). It’s often recommended to consult with or hire a professional for proper and safe installation.
