Interesting, did he mention whether this is a frequent issue with these Appolo units? ONE TEAM - ONE FIGHT!!! Mike I am currently having the same problem as Iggy Dalrymple. An HVAC person told me that the solinoid valve is not working in my unit. Currently I have heat but no A/C. The problem is I can't find anyone capable of working on the system and no one can seem to order the replacement part. I'm in Santa Clara, CA. Any recommendations for how to order the part and who I can get to work on my system is greatly appreciated. Natalie
