• Oversized units may cool too quickly without removing sufficient humidity, leading to discomfort

Pro tip: Use 20 BTU per square foot as a baseline, adjusting for ceiling height, insulation, and climate.

Energy Efficiency Ratio (EER)

The Energy Efficiency Ratio (EER) measures how efficiently a Crane air conditioner converts electricity into cooling power. It is calculated by dividing the cooling output (in BTUs) by the electrical input (in watts) under standardized conditions (typically 95°F outdoor temperature).

• Most Crane models have EER ratings between 9.0 and 12.0, with higher values indicating greater efficiency
• An EER of 11 or higher is considered energy-efficient and may qualify for utility rebates
• High EER units reduce electricity bills and environmental impact by minimizing power consumption
• Look for ENERGY STAR® certified models, which meet strict efficiency guidelines set by the U.S. EPA

Key insight: A unit with an EER of 12 uses about 25% less energy than one with an EER of 9 for the same cooling output.

Noise Levels

Noise output, measured in decibels (dB), is crucial for comfort—especially in bedrooms, offices, or healthcare environments. Crane air conditioners are engineered for quiet operation, but noise levels vary by model and cooling mode.

• Modern Crane units operate between 48 dB (whisper-quiet, comparable to a library) and 60 dB (similar to normal conversation)
• Lower noise levels are achieved through insulated compressors, optimized fan blades, and vibration-dampening mounts
• Many models include a "sleep mode" that gradually reduces fan speed and noise overnight
• Portable and window units tend to be slightly louder than split systems due to internal compressor placement

Customer consideration: Recommend low-noise models (under 52 dB) for light sleepers or noise-sensitive environments.

Refrigerant Type

The refrigerant is the working fluid that absorbs and releases heat during the cooling cycle. Crane air conditioners use advanced, environmentally responsible refrigerants that comply with international regulations.

• Most current models use R-410A, a chlorine-free refrigerant that does not deplete the ozone layer
• R-410A operates at higher pressure than older R-22, improving cooling efficiency and system reliability
• Newer eco-friendly alternatives like R-32 are being introduced for even lower global warming potential (GWP)
• All Crane units are pre-charged and sealed, requiring no refrigerant maintenance under normal conditions

Environmental note: Proper disposal and refrigerant recovery are required by law—never vent refrigerant into the atmosphere.
