I thought I posted an update here but guess not. We had an NCS tech come out and clear all the chemical and water lines. That is basically all they did. I ended up getting 4 space heaters and inside the engine / chemical room near the chemicals and installed a wifi thermostat. Temps never dropped below 30 iirc. My engine room isnt fully enclosed as the ceiling is open to the bay so I suppose the space heaters weren't really that effective. In any case, i didnt have any major damage. There were a few plastic parts near the top roof brush that cracked but I am not even sure if that was because of the freeze. I dont blame you guys laughing at us in the south!
