After switching from my original HVAC installer by requesting a second opinion on a heat exchanger, I joined Watkins Protection Plan. I was able to arrange my A/C tuneup just days before my original 10 year warranty expired. Chris did an excellent job on the tuneup and luckily there were no problems. Watkins 1st visit did find a problem that required a new motherboard that was covered under Trane's parts warranty. c
