NO AC CARRIER SYSTEM FROM 2014 LAST SERVICED ON MARCH 23rd The clients concern was the top floor unit located in the attic. She advised me that they had a power outage about a week ago. I reset all breakers and called for fan. The variable speed motor never kicked on. I called for ac and the ac never kicked on. I went to the air handler in the attic and I immediately noticed the line set was completely frozen. I opened up panel and I smelled a burnt smell and I noticed the whole evaporator coil was frozen. I touched the motor and it was hot , I touched the transformer and it was very hot. Nothing can be done right now because first , the motor , transformer and board got hit and for those three parts we will need to check for availability. While that’s being waited on, the unit will de ice itself. We will need to check the compressor and pressures once it de ices itself only because the outdoor unit was running without any indoor fan and that could’ve caused the ice up. Keep in mind
