10-ton AC units are frequently installed in 5,200 to 6,400 sq.ft. commercial buildings. This includes offices, retailers, and eating establishments. Air conditioners of this size come in several qualities and efficiencies. More efficient models may have variable-speed air handlers, lowering monthly costs. However, these have higher upfront costs.

In addition to your unit’s quality and efficiency, other factors can influence your project’s cost. Commercial air conditioners are usually installed outside the building or on the roof. In this case, you may have higher installation costs. Costs also increase if the current setup or ducts must be modified to install the system.
