What Defines A 4 Ton AC Unit?

A 4-ton air conditioning unit delivers approximately 48,000 BTUs of cooling per hour. This capacity is ideal for homes spanning 2,200 to 2,700 square feet, depending on climate and insulation. For Carrier units, the 4-ton measurement is standardized, but actual performance depends on installation, ductwork, and local environmental factors.

The term “ton” refers to the amount of heat required to melt one ton of ice in 24 hours. 4-ton units are often used in large residential properties or smaller commercial spaces requiring robust, consistent cooling.

Factors Affecting Carrier 4 Ton AC Unit Price

Several factors impact the price of a Carrier 4-ton AC system beyond the advertised unit cost. Understanding each can help control your project budget:

Estimated Operating Costs For Carrier 4 Ton AC Units

Annual operating cost is a crucial consideration for American homeowners. Actual usage will vary by climate, insulation, and runtime hours, but approximate values for a 4-ton Carrier AC are as follows:

SEER Rating	Avg. Annual Cost (U.S. Avg)	Avg. Annual Cost (Hot Climates)
