Frequently Asked Questions about Keystone Air Conditioners
Shopping for an air conditioner can bring up a lot of questions. Here are some common queries about Keystone air conditioner reviews and their features to help clear things up:
Q1: What does BTU mean, and how do I choose the right BTU for my room?
A: BTU stands for British Thermal Unit, and it’s a measure of an air conditioner’s cooling power. Generally, you need about 20 BTUs per square foot of living space. So, a 150 sq.ft. room needs around 5,000 BTUs, while a 500 sq.ft. room would need about 10,000 BTUs. Factors like ceiling height, sun exposure, and the number of windows can also influence the ideal BTU.
Q2: What’s the difference between a window AC and a through-the-wall AC?
A: A window AC unit installs directly into an open window, blocking a portion of the view and potentially requiring removal during colder months. A through-the-wall AC unit, as its name suggests, is installed into a cut-out opening in an exterior wall. This offers a more permanent, less intrusive solution, preserving your window view and providing a cleaner look.
Q3: Do Keystone air conditioners come with heating functions?
A: Yes, some Keystone models, particularly the wall-mounted units, come with supplemental heating capacity. It’s important to note that this “supplemental heat” is designed to assist during milder cold periods and is not intended to be a primary heat source for your home, especially in very cold climates.
Q4: How do the ‘Energy Saver’ and ‘Sleep’ modes work?
A: These modes are designed to reduce energy consumption. In ‘Energy Saver’ mode, the fan and compressor cycle on and off to maintain the set temperature, only running when needed. ‘Sleep’ mode gradually increases the temperature by a few degrees over several hours, then holds it, allowing for comfortable sleep while using less energy.
Q5: Is a smart remote control really useful, or just a gimmick?
A: A smart remote control, like those found with Keystone ACs, is very useful! It typically has a built-in thermostat that senses the temperature right where you are in the room, not just at the AC unit itself. This allows for more accurate temperature control and ensures your immediate vicinity is truly comfortable, rather than relying on a sensor far across the room.
Q6: Can I install a Keystone through-the-wall air conditioner myself?
A: While some handy homeowners might tackle a through-the-wall installation, it’s generally recommended to consult a professional. It involves cutting a precise opening in an exterior wall and often requires a dedicated 230-volt electrical outlet, which might need specialized wiring. Window units are typically much easier for DIY installation.
Q7: How important is the dehumidifier function in an air conditioner?
A: Very important! Beyond just cooling the air, reducing humidity significantly increases comfort, especially in muggy climates. High humidity can make 75°F feel much hotter and stickier. A good dehumidifier function also helps prevent mold and mildew growth, contributing to better indoor air quality.
We hope these Keystone air conditioner reviews and FAQs have given you a clearer picture of what these reliable units have to offer. Whether you’re looking for ultimate power, quiet operation, or year-round versatility, there’s likely a Keystone model that fits your needs perfectly. Stay cool!
