Cooling Capacity (BTU)

BTU power rating determines the size of the area an AC can cool. Units from 6,000 to 15,000 BTU are common for small spaces like rooms, RVs, or campers. Oversized units waste energy, while undersized units fail to cool effectively.

Ducted vs. Non-Ducted Systems

Ducted air conditioners distribute cooling through vents and ductwork, allowing even airflow in multiple rooms or large enclosed spaces. Non-ducted systems deliver cooling directly, suitable for smaller or mobile spaces without complex duct installations.

Energy Efficiency and Power Source

Consider inverter technology, power consumption (kWh), and whether the unit supports DC power for battery-powered vehicles or solar compatibility to reduce energy costs.

Noise Level

Quiet operation is essential if the unit will be used in bedrooms, RV sleeping areas, or offices. Units operating below 55 decibels provide undisturbed comfort.

Control Features and Smart Technology

WiFi or remote control functionality offers convenience for adjusting settings remotely. Programmable thermostats and smartphone app compatibility enhance user experience.

Installation and Maintenance

Check for ease of installation, especially for window units and rooftop models. Removable filters and simple access for cleaning prolong unit lifespan and efficiency.

Operating Temperature Range

Ensure the unit performs well within your local climate’s outdoor and indoor temperature variations for consistent comfort throughout the seasons.
