Will a 5 ton a c condensing unit work with a 4 ton coil?

Yes, a 5-ton AC condensing unit can work with a 4-ton evaporator coil, but it may not operate optimally. The mismatch can lead to issues such as reduced efficiency and potential short cycling, as the larger condensing unit may cool the space too quickly without allowing the coil to effectively absorb heat. It's generally recommended to match the sizes of the condensing unit and coil for optimal performance and efficiency. Always consult with an HVAC professional for specific compatibility concerns.
