Changing a condenser

[chuckster2112]

I need to change out a 5 ton 10 seer R-22 condenser. My question is at this time I cannot change the evap. coil. I'm getting a 13 seer dry condenser, because of the seer rating should I put in a 4 ton condenser instead of the 5 ton?

No. Keep the new condenser at 5 tons. My experience is that a ton less is more likely to result in reduced head pressure, bubbles in the liquid line and reduced btu/hr of cooling when you need it the most, July and August.

Be sure to get the refrigerant charge precisely correct.

I always advise switching to 410A. R-22 prices are skyrocketing right now despite there being almost 7 years to go before the phase-out is finished. Sticking with 22 will likely cost you more in the long run than the price of a new 410A coil.
