David came by to our New Braunfels property today and he did a wonderful job in explaining what is happening with our AC system and what needs to be done to fix it, he shows care not just with the AC but also with the guests staying. Thank you!

David came promptly and was extremely conscientious, even reading the instructions on my new unit. He was done in no time and it was a perfect set up.

Ronnie provided excellent customer service!!! I am usually a skeptic so if a company offers a free service- the first thing I think is either they will come and find many things they need to fix and then charge an arm and leg or they do something that will make the device break within 30 days. Then they will expect me to call back for paid services! I still went through with the CPS recommended cleaning and eval. This is day 1- Ill be back if something surprising happens in the next 30 days ! Lol Anyways, Ronnie was awesome at this visit!!

Sigma Air Heating & Cooling's reply

Thank you so much for your kind words, Kimberly! I'm glad to hear Ronnie was able to deliver the quality service you were hoping for during your CPS cleaning and evaluation. We appreciate you giving us the opportunity to dispel any doubts, and we look forward to assisting you in the future.
