"He had the same conclusion as yours says it is short cycling due to leaking of freon." I did not say the short cycling could be due to a freon leak. I did say it could be due the condenser being increased in size. I don't understand how a loss of freon could cause a condenser to short cycle. Perhaps you misunderstood what the contractor said. But if he made that statement then my confidence in his ability continues to go down. What exactly was replaced? So far I know it was the condenser. I hope he replaced the coil in the attic. Was the furnace also replaced? What about the line set (the copper tubing running from the attic to the condenser outside}? Normally on an attic installation that is not replaced since it is running inside walls. The old line set can be reused but it must be flushed out properly. You can't mix the old and new refrigerants. But, if the condenser was increased in size, the line set may be too small (diameter) to work properly. This is another reason not to be increasing the size of the condenser. Has the contractor returned yet? If there were air flow problems while running the AC, then there will be air flow problems with the furnace. Those have to be fixed. Make sure the air flow works well in the spare bedroom. Just because you rarely use it does not mean it should not heat and cool properly. All bedroom vents should have approximately equal air flow. This should not be too difficult with the furnace installed in the attic.

Thanks for the replies. I have an old unit (propane). I guess if part of it is outside and part is in the attic, I have a split-system? The brand is Coleman Evcon Model No. BRCS018B, so I have a 1.5 ton unit? I couldn't find the SEER via search. I am wondering how I can lower my energy bill N. Calif (PGE) that runs high in the summer. Trying to determine how efficient the unit is, and if it's feasible to run it off solar possibly. I search and see the tonnage size helps determine the number of solar panels? So, my 1.5 ton will need how many panels? And how much per panel, is what I'm ultimately trying to determine if it's worth changing... I look forward to any helpful replies/coments
