Taking Care of Our Customers Since 1987!

I've known and used Sierra Air since they opened their doors and I wouldn't use any other company in the Las Vegas Valley.
“I've known and used Sierra Air since they opened their doors and I wouldn't use any other company in the Las Vegas Valley. Darren the owner has always been fair and willing to discuss any issue or question I've had throughout the years. I started with the Honeywell Electrostatic Filters in the attic of my second & third house and currently have the Lennox Air Purification System. On Nov 4th, 2016 Zachary the service technician was incredibly thorough and I forgot at times he was in the house as I went along my daily business.....and yes, Nikole D called the day prior and 45 minutes prior to Zachery's arriving providing exceptional customer service by keeping me informed without disrupting an entire 4 hour window of my day! THANK YOU....Sierra Air is the BEST COMPANY in Clark County in my opinion.”

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.”

The people who work for Sierra LLC are exceptional.
“The people who work for Sierra LLC are exceptional. They are very knowledgeable and always know how to answer my questions and give me the best options. They are courteous and kind also, and I feel I can trust them to be honest. They are careful in my house, which is very important to me. They go above and beyond the minimum, and they take the time to explain everything to me. I trust the associates of this company with my heating and a/c needs which is as important as choosing a doctor in this town. When so many companies only care about how much money they can get, it's nice to be have a company like Sierra.”

Nicholas & Irene D.
This is the kind of service that I look for in a company and Sierra Air has that service.
“I had service on my Heating Unit today and it all started with the office staff. Yvonne B. called a few times to let me know when service was being performed. She was so very nice and polite on the phone with me. She was very professional. When the service tech Zachary R. arrived he introduced himself and asked me if there were any problems. He was very kind and listened to what I had to say. He asked me to show him around so he knew where he was going to be working. He performed his service in a very professional manner. I was very impressed with his knowledge and how he explained the work that was done on my system. This is the kind of service that I look for in a company and Sierra Air has that service. I have been dealing with them for three years now and would not have anyone else to service my system.”
