Does anyone still use over size Air Handler?
Some years ago, it was not unusual to see an over sized Air Handler. Like a 2 !/2 condensing unit paired with a 3 ton air handler. These days systems are designed to be highly efficient. So I'm wondering if there is still an advantage to an over size air handler, or if it will just cause problems.
Case in point, I'm working on some condo's that have height restrictions. I found the Goodman AWUF wall mount units that will work. The problem is that they are only 13 SEER. The owner wants to replace with higher efficiency. I plan to add a TXV which will make 14 seer, but if I over size the A/H by 1/2 ton, will that help? The condos are currently running 2 1/2 ton which is about right.
