Had a lightning strike real close and fried a circuit board and transformer in upstairs furnace (Armstrong Ultra SX80). Contractor replaced parts, left, still no cold. Contractor returned same day a to find outside 'compressor shorted to ground and positive acid test in refrigerant'. Quoted on the spot for a replacement condenser for the upstairs system (currently Armstrong 2.5 ton 11-12 years old Seer 10).

Contractor recommendation was for a Goodman 2.5 ton Seer 13 but they didn't do any sizing work that I could see...

In the previous 6 months I have had the Evap Cooler on the same system replaced with a Trane Seer 13 due to 'leak' in the old cooler.

Know that I need to seek additional quotes but do I need to have a Trane Seer 13 Condenser to match the Trane Evap Cooler or will any Seer 13 equipment match up OK.?

Just checked the new cooler upstairs and it says R22 only...

Any help would be greatly appreciated....
