Michael was prompt, friendly and professional. Did a very thorough maintenance of our system. Was able to answer all questions to my satisfaction. On the spot ordered a part that was missing. Thank You, Michael!!
These two techs that came to my home were very professional, knowledgeable, and very friendly. I am so glad to have found the help in Sierra Air! I would give 10 stars if possible.
I am happy with the service calls, I signed up for the Home Comfort Club. So far everything is good.
The entire experience of removal of my old system and replacement with a new system was conducted smoothly. I closely observed the workers and witnessed their excellent workmanship. They are to be commended for a completely satisfactory performance.
