Price Comparison
The Keystone 12 is priced at $449.99, while the LG 5000 BTU is significantly cheaper at $189.00, making it about 58% less expensive. This substantial price difference is a critical factor for budget-conscious consumers. The Keystone 12 not only serves as an air conditioner but also includes supplemental heating and dehumidification features. However, if you are only looking for basic cooling, the LG model's lower price offers excellent value, especially for small spaces.
Cooling Capacity
The Keystone 12 boasts a cooling capacity of 12,000 BTU, designed for medium-sized rooms up to 550 square feet. In contrast, the LG 5000 BTU is suitable for smaller areas, effectively cooling spaces up to 150 square feet. If you need to cool a larger area, the Keystone 12 is the clear winner. However, the LG model is ideal for small rooms, making it a perfect choice for bedrooms or personal offices with limited space.
Heating and Dehumidification Features
The Keystone 12 offers both cooling and supplemental heating with an 11,000 BTU heating capability, making it versatile for year-round use. Its heating mode is meant to be utilized at temperatures between 23 and 76 degrees Fahrenheit. On the other hand, the LG 5000 BTU is strictly a cooling unit with no heating option. If you live in an area where heating is necessary during colder months, the Keystone 12 provides significant advantages over the LG model.
Noise Levels
The LG 5000 BTU operates at sound levels as low as 50dB, making it a quiet option for residential settings. The Keystone 12 does not specify its noise levels, but larger units typically tend to be noisier. If noise is a concern, especially in bedrooms or study areas, the LG model may be the better choice, as its design prioritizes quiet operation without sacrificing performance.
Ease of Installation
Both products promise easy installation but cater to different window sizes. The LG model features a fixed chassis and comes with an EZ Mount installation kit, suitable for double-hung windows measuring between 21 to 35 inches wide. The Keystone 12 also includes a window installation kit but requires a specialized 230V/20-amp electrical outlet, which may not be readily available in all homes. For consumers looking for a hassle-free setup, the LG 5000 BTU offers a more straightforward installation process.
Energy Efficiency
The Keystone 12 includes an 'Energy Saver' mode and a 'Sleep' mode, aiming to reduce electric bills and improve efficiency. Although specific energy consumption ratings are not provided, the features suggest a focus on energy savings. The LG 5000 BTU also includes an energy-saving function, which can help lower electricity bills. If minimizing energy costs is a priority, both models present energy-efficient features, but the Keystone's added modes may provide greater flexibility in energy management.
User Convenience
The Keystone 12 comes with a smart remote control that measures the room's temperature and adjusts the cooling accordingly, offering a high level of user convenience. In contrast, the LG 5000 BTU uses simple mechanical controls, which are easy to understand but lack the advanced features of the Keystone. For tech-savvy users or families seeking convenience, the Keystone 12's remote control functionality may be a more attractive option, while the LG’s straightforward controls may appeal to those who prefer simplicity.
Which should you buy?
Choosing between the Keystone 12 and the LG 5000 BTU ultimately depends on your specific needs. If you're looking for a powerful unit that can cool larger rooms and provide supplemental heating, the Keystone 12 is worth the higher investment at $449.99. However, if your focus is on cooling small spaces and you need a budget-friendly option, the LG 5000 BTU at $189.00 is a solid choice. Each product serves distinct purposes, making the decision largely dependent on room size, heating needs, and budget considerations.
