Superior has been added to my contacts.i have had 3 companys out here. Superior had troubleshooting skills.unfortunately was told I needed a new one. Was told why and how system works. It's now 95 outside and 72 inside. This is a first. My daughter just had major surgery and could not go another day without air. They put in next day. Cleaned up after themselves. I dealt with dan,Ross and mark ,also a new hire. A+++++. I will spread the word and they are now my only hvac company.. If your Leary of people like me. Don't need to be in this case😄
