BTU/hr
British Thermal Units per hour is the most common measure of cooling capacity in North America. One BTU is the energy needed to cool one pound of water by one degree Fahrenheit.
—
Tons of Refrigeration
Tons of refrigeration is commonly used in HVAC industry to describe AC capacity. One ton equals 12,000 BTU/hr, representing the cooling power needed to freeze one ton of water in 24 hours.
—
Watts
Watts measure the electrical power consumption of your air conditioner. This helps you understand energy usage and compare different AC units for efficiency.
—
Horsepower
Horsepower is sometimes used to rate compressor motors in air conditioning systems. One horsepower equals approximately 746 watts of electrical power.
—
Estimated Daily Cost
The estimated cost to run your air conditioner for the specified number of hours per day at your local electricity rate. This helps you budget for cooling expenses.
—
Estimated Monthly Cost
The projected monthly electricity cost based on your daily usage pattern (calculated as daily cost × 30 days). Use this to estimate seasonal cooling expenses and compare AC units.
