The typical 2,000-square-foot house will need a central air conditioning unit of about 3 tons or 36,000 BTU. The larger an air conditioning system, the more it will cost. A 2,000-square-foot home needs an air conditioner of between 2.5 and 5.0 tons, equivalent to 32,000 to 60,000 BTUs. A general rule of thumb is to calculate 20 to 25 BTUs per square foot.
Therefore, for a 2000 square foot home, a cooling capacity of 40,000 to 50,000 BTU is needed. The cost of an HVAC system for a 3000 square foot space will vary depending on the type of system, the quality of the equipment and the complexity of the installation. By carefully selecting and installing a suitable air conditioning system, homeowners can enjoy a comfortable and efficient indoor environment throughout the year.
