I used Sun Energy for 9 years, from 2001-2010 for my a/c service which was installed by them. In the 9yr span I had my a/c serviced yearly to keep my warranty valid and every year they took care of me and replaced any worn out parts with no extra charge to me but the initial yearly service fee. I had my unit replaced last year due to hail damage and went with a Trane unit, which Sun Energy doesn't carry . Since then I have had nothing but headaches, the contractor who installed the unit was an idiot and I chose a new service company for the extended warranty and all they care about is selling me things I don't need. When I did have an issue, the new company I chose did not want to fix the problem under warranty. So now I am in search of another A/C company to service my unit. If Sun Energy carried the Trane brand I would not hesitate to use them again.
