  • There is a certain security knowing it will work when you need it to, and since our AC is the biggest most expensive appliance in the house there isn't another company I would want to service it.

    “Have been with Sierra on contract since having a problem with my system 2 years ago. They check it 2X a year and have had no problems since. There is a certain security knowing it will work when you need it to, and since our AC is the biggest most expensive appliance in the house there isn't another company I would want to service it. Every one of the Techs that have come out have been very friendly, polite, professional, and clean. Matt is very knowledgeable and easy to like, as this has been my experience with the rest of the Sierra team.”

  • We have been using Sierra Air for over 10 years and trust them to take care of a very important part of living in this harsh desert.

    “We have been using Sierra Air for over 10 years and trust them to take care of a very important part of living in this harsh desert. Sierra Air helped us to limp along with an aging a/c heating system for many years as economically as we could, before we upgraded last year. We did not consider anyone else to perform our install of our new Lennox System. Yesterday, Tyrone performed the first service of the heating portion, with the a/c service being done last April. Tyrone's care in entering our home was very professional and I would not want anyone else. Thanks to Sierra Air, Tyrone and the other professionals at Sierra Air in Las Vegas.”

  • There is no question who I will call in the future

    “I just wanted the world to know how grateful I am to have Sierra, LLC come to my home today to explain and adjust my heating system. Jesus S. was courteous, detailed oriented, showed high technical expertise, knowledgeable, sociable and dedicated to customer satisfaction. This a company who keeps me in mind. Kudos to Jesus and Sierra. There is no question who I will call in the future.”

  • Our technician Darryl was very thorough, honest and informative.

    “Our technician Darryl was very thorough, honest and informative. He did a great job maintaining our unit and showed us before and after photos. He was on time and cleaned up any mess before he left. I would definitely recommend Sierra for all of your HVAC needs.”

  • I appreciate the care they take in your home

    “I am impressed with Sierra Air. I have received service twice from their company. I appreciate the care they take in your home--wearing shoe covers and placing a drop cloth on the flooring before setting their ladder down. (And they bring their own ladder! I've actually had an HVAC technician ask to borrow one :) Tim D was extremely polite and professional. He was patient in taking the time to discover the problem I had called about. 'Cause wouldn't you know, the sounds I had been hearing weren't happening when he got there. He really took the time to figure out what might be causing the concern I had. I'm glad he didn't give up because he finally got to hear what I had been talking about. He had assured me that the problem we were having would be resolved that day. He also addressed another smaller concern. And he gave me tips on setting my thermostats and the types of filters I should use. Give Tim a bonus! :)”
