Sometimes manufacturer's, like Rheem/Ruud, rate their residential air handlers in whole number intervals, though each can be tech-modified between two speeds, depending on the heat load/condensing unit. In your case, it might already be set to low speed, or 1000 CFM (high speed option operates at 1200 CFM). If this is the case, then the larger evap. coil supposedly gives you a slight SEER boost, like bornriding said. Are there any complaints about its operation??

In what situations would a 3 ton airhandler be installed with a 2.5 compressor? I had started a thread yesterday regarding my parents AC which is set up this way but was wondering if anyone can clarify why a contractor would have done this and if it safe or efficient or technically correct to do.
Also, can it be done the other way? ie.) 2.5 air handler with a 3 ton compressor?
Thanks again for all the advice. This is a great site.
