I hired these guys to inspect my 3 systems that have not been looked at for at least 4 years. The tech ,ELJ, was here for 3.5 hours and did a very thorough inspection. Explained how to program thermostats and explained how my whole house circulation system worked. NV Energy tech and his department heads had no clue what this system was.
They are very competent people and I was very impressed. As a retired engineer I had a lot of questions. They are definitely my GOTO A/C repair company..
