During the build of my dedicated HT room I requested a 1 ton, 300 CFM split ducted system to be installed. Unfortunately what got installed was a 1.5 ton 450CFM system (Goodman GSX 130181BA compressor with matching Goodman air handler). I was ill at the time and didn't discover what had happened until after the project was complete and both my contractor and HVAC company had gone bankrupt...I was their last job.
The HVAC system is dedicated to the HT room and cannot be ducted to the main home due to isolation issues etc.
Has anybody got any ideas how I can effectively reduce its cooling capacity to 1 ton or less as the air entering the room is far too cool. I have reduced the air flow to about 350 CFM and the unit never ices as it is on for such a short time. The room is only 1900 cubic feet and I only need 0.75 tons to cool the equipment and people.
A few ideas that I had were:
1. Altering the speed of the compressor using an inverter. Not too sure if this is possible with the Copleand Scroll compressor.
2. Looping the air handlers send return and using a damper & freezstat (just in case).
3. Adding a 1.5KW electrical heater to the air handler to come on with the compressor.
I cannot replace the system due to shortage of funds so I am looking for a cost effective fix.
Any advice/help please.
