Cooling capacity (BTUs) for a 1 HP condensing unit varies depending on operating temperature range (Low Temp vs. Medium Temp) and refrigerant used. Typically, a 1 HP medium-temperature unit delivers approximately 7,500 to 10,000 BTU/hr under standard R-404A / R-448A operating conditions. Please refer to the specific model performance chart with your operating suction temperature for exact BTU output.
