The RecPro RV Air Conditioner 15K is designed with a substantial cooling capacity of 15,000 BTUs, making it suitable for cooling spaces up to 835 square feet, which is ideal for larger RVs, fifth wheels, and even food trucks. One of its notable features is the integrated heat pump, providing both heating and cooling functionalities in one unit, enhancing its versatility throughout the year.

Additionally, the unit is equipped with a remote control that offers various functions including dehumidifying, dry, sleep, and timing modes, ensuring convenience and comfort for users. However, it is important to note that the remote control is stored inside the AC unit display during shipping for protection, so be sure to retrieve it upon installation. The unit also includes exterior shroud and interior plenum components, facilitating easier installation on flat roofs with less than a 5-degree inclination. Potential buyers should be aware that it doesn't work with other brand wall thermostats, which could limit compatibility with existing systems.

The noise level of 55.4 dB is relatively quiet for an RV air conditioner, ensuring a more peaceful environment. Despite its considerable weight of 112 pounds, the ease of installation is highlighted in the product description. The energy efficiency ratio (EER) of 2.6 is lower compared to some other units, which might result in higher energy consumption. The RecPro RV Air Conditioner 15K is a robust unit, offering significant cooling power with added heating capabilities and a suite of convenient remote features, making it a solid choice for those needing a reliable and versatile air conditioning solution for their RV or similar environments.

The RecPro RV Air Conditioner 13.5K is a good choice for RV owners who need a reliable and efficient cooling solution. With a cooling capacity of 13,500 BTU, it can effectively cool a space up to 351 cubic feet, making it suitable for most RVs, fifth wheels, and even food trucks. One of its standout features is its low amp draw, allowing you to run other appliances simultaneously without overloading your power system. This is particularly useful for those who live in or frequently travel with their RVs.

The unit also includes a dehumidifying function, which helps to keep the air fresh and comfortable by reducing excess moisture. This is especially beneficial in humid environments or during muggy weather. Additionally, it operates at a low noise level of 59.7 decibels, which is comparable to gentle rain, ensuring minimal disruption to your peace and quiet or sleep. The unit is designed for easy installation, making it a convenient option for those who prefer a DIY approach.

Its all-in-one design includes a touch screen LED display and a remote control, offering a range of functionalities such as cooling, dehumidifying, dry mode, sleep mode, and timing. However, its energy efficiency ratio (EER) of 8.5 is relatively moderate, meaning it may not be the most energy-efficient option available. The dimensions of 39.5 x 25.5 x 13.5 inches make it quite sizable, so you'll need to ensure you have adequate space for installation. Additionally, while the unit is crafted from durable plastic, it may not have the premium feel of some higher-end models. In summary, the RecPro RV Air Conditioner 13.5K is a solid and functional option for those seeking a balance of performance, ease of use, and additional features, though it may not be the most compact or energy-efficient choice on the market.

The Coleman 48204C866 Mach 15+ A/C Unit boasts a robust cooling capacity of 15,000 BTUs, making it suitable for larger RVs. This high capacity ensures rapid and efficient cooling, which is a significant strength for those traveling in extremely hot climates. The unit also offers 5,600 BTUs of heating output, adding versatility for different weather conditions. With an energy efficiency rating (EER) of approximately 8.3 (derived from its wattage and BTU), it offers decent energy efficiency, though not the highest in its class. Its noise level is an impressive 28 dB, which is relatively quiet and should contribute to a more comfortable environment inside the RV.

Installation might require professional assistance given its weight of 90 pounds and dimensions, but the unit is designed for durability and strength, which can be a trade-off for the more cumbersome install process. The eco-friendly refrigerant (R-410A) and a sturdy, brushed exterior are notable additional features that enhance its appeal. However, users might find the unit a bit bulky, and its substantial size (28”D x 42”W x 16”H) could be a constraint for smaller RVs.

The Coleman 48204C866 Mach 15+ is a solid choice for RV owners needing strong and reliable cooling and heating performance, particularly those with larger spaces to manage.
