Lightning Strike Help
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....
Get a Trane to match.....
And a better contractor for sure......
And maybe one day, your Frankenmonster will look half normal again.

If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.
match the system.
check into your insurance too.
I'd match the system too but if the burnout was bad, insurance should replace the indoor coil & lineset. They are contaminated and even trying to clean up could leave some acid behind that could cause problems later.
I agree 100%. And while you're at it, upgrade to an R-410A system.

Arcing is burning, creating acid in compressor oil (which is always on windings and etc.) Before compressor stops running completely, it manages to pump enough burned oil throughout the system to warrant an extensive clean-up or replacement of various refrigerant circuit components.
If lightning directly strikes the power supply, it's beyond obvious why everything fries. The above was to illustrate that lightning does not need to directly contact the power supply or structure to cause damage. I personally witnessed this at one of my former houses...lightning sailed right over the power lines in the alley behind our house, without hitting it, spiking the voltage and taking out our furnace circuit board. Fortunately we had unplugged our computers and other electronics, as we always try to do when a thunderstorm blows up, so nothing else was lost.
Thanks for all the help from everybody who replied.....Now that I know that I probably will be having the coil and line sets replaced as well what would be the pros and cons of having the 12 year old Armstrong furnace replaced while
having everything else done.
Have had no problems with this unit at all up until this point. And Iraq Veteran....it is quite a funny looking fellow up in the Attic!
