Buying Guide for Roof Mounted Air Conditioners

When selecting the best roof mounted air conditioner, consider these crucial aspects to match your cooling needs and installation requirements:

Installation Type

Rooftop vs Through-the-Wall: Rooftop units are common in RVs and campers, providing space-saving, weather-resistant cooling. Through-the-wall units fit permanently in walls, ideal for small rooms or offices. Confirm compatibility with your installation area before purchase.

Cooling Capacity (BTU)

BTU rating should correspond to the size of the space being cooled. Small rooms may only require 5,000 to 8,000 BTU, while larger RVs or multi-room setups benefit from 10,000 BTU or more. Overpowered units waste energy; underpowered units struggle to maintain comfort.

Power Source and Efficiency

Consider whether the unit is powered by standard AC electricity or DC power (12V) as in vehicles. DC-powered rooftop ACs run off vehicle batteries and are efficient for mobile use. Look for units with high EER ratings or eco-friendly refrigerants like R-32 for better energy savings.

Heating Options

Some roof mounted air conditioners include heat pumps, providing both cooling and heating. This feature can extend comfort during colder months, eliminating the need for a separate heater.

Noise Levels and Operation Modes

Quiet operation is a major factor, especially for sleeping areas or small enclosed spaces. Units with multiple fan speeds, energy saver modes, and sound-dampening designs improve user experience.

Control Features

Remote controls and smart WiFi-enabled units offer flexible operation. Advanced controls let you adjust settings conveniently, set timers, or integrate with smart home systems.

Durability and Weather Resistance

For rooftop units, UV protection, rugged construction, and resistance to rain and dust increase longevity. Materials like UV-stabilized plastics and zinc coatings help withstand outdoor conditions.

Size and Profile

Low-profile units reduce wind resistance and improve aerodynamics, which is important for RVs when driving. Compact designs also simplify installation and prevent intrusion into interior space.

By evaluating these factors in relation to your specific use case—whether RV cooling, a small room, or office—you can select a roof mounted air conditioner that delivers efficient, reliable comfort all year round.
