Since carrier is due to come out with a modulating compressor in June, and there are other modulating systems on the market. I have been thinking about how you can use this to customize the system for different scenarios.
We will use my house as the scenario. Duct is sized properly for 4-ton.
If we assume that a modulating system can operate a 3 ton range. i.e. 2-4 ton or 3-5 ton.
Would I run into problems if I oversize to 5-ton for the extra heating capacity in winter since it would most likely only run in 5-ton operation when it is extremely hot or cold. In the non extreme weather it would probably run in 3-4 ton range
What harm is being done running 5-ton when the ductwork is designed for 4 ton?
Obviously I would loose out on a little efficiency in the summer while dehumidifying since a properly sized 4-ton system would be able to go to 2-ton operation during humidification.
Sound logic, or newb failboat
