This place told us we needed a new coil for our Trane unit, and then said it wasn’t covered under warranty(2005 home). Thankfully, a great christian man from my church who lives 45 minutes away came to give it a look and we learned that it didn’t need a coil ATALL… we later needed additional service & found out the entire unit was still under warranty. So… C & R was a rip-off more than once…
