The compressor fried on my 1998 Rheem 10 Seer 5-ton unit and I am in the bidding process for a replacement. I am looking for a few objective second opinions.
Our Rheem 10 seer 5-ton installation was never right. It seemed the furnace & AC seems to cycle too often, did not seem to cool the house well and we dislike the noise and disruption of the furnace blowing at full speed when the AC is on.
Is smaller and slower better? A local contractor recommended that we replace with a 4-ton unit. The logic being the line set is too small for a 5-ton, the ducting seems to not support the 5-ton and a 4-ton would run longer doing a better job of cooling the house. Does it this seem right and like a good idea?
If I should downsize to a 4 ton.
- Can we use the existing 5-ton Rheem coil and adjust/replace the flow rate?
- We would much perfer a slower, less noisy blower speed and to run the AC longer. Can the ComfortMaker RJ2 with a General 90 50A50 and a 2000cfm blower with 4 speeds be made to run a lower speed setting (rather than high) and the AC tonage & coil sized to that lower cfm setting?
