  • I would highly recommend Sierra and their customer service

    “Since we moved into our new house we have heard a noise . At really odd times, so bad my daughter would be kept awake. During the day I had thought the banging was the homes being built, I notified our builders supervisor to make an appointment for a warranty call. I think he thinks we were hearing things. Tony came out this morning and listened to us, then went above and beyond to find the problems. In this heat he went in the attic, and he found a long metal tube left over from construction which was part of the problem, then he tightened everything and insulated to make sure we have no more banging. We give him an A plus, plus. Also Yvonne in the call center was great communicating with us. I would highly recommend Sierra and their customer service. Especially Tony.”

  • 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.”

  • Jared provided value-added service that educated me on the various options for more efficient and healthy air filtration. Thanks Jared for the friendly conversation, information and great inspection.

    “Today, Thur, Mar 23, 2017, Jared provided us an inspection of our air conditioning. The best i can say about him may not be sufficient. He was professional, courteous, and knowledgeable. He even took his booties off and on after i told him he didn't need to. Jared was not hurried, he even was friendly to my sheepdog, Vinnie. Once he was done, he answered a number of my questions. Prior to starting, Jared gave me a packet of info to read through, and I had questions. He stepped through each of my questions offering a detailed explanation on the membership program, filtration systems, thermostats, and water heater. Jared provided value-added service that educated me on the various options for more efficient and healthy air filtration. Thanks Jared for the friendly conversation, information and great inspection. Were are set for the heat. Sierra LLC, the confidence you have placed in Jared is well-founded.”

  • Sierra Air is very professional and offers great service.

    “Sierra Air is very professional and offers great service. Today, my technicians Wayne and Dan did an excellent job on the maintenance of my units (I have 7) Dan even took the time to draw a diagram for me to show how my system works. Everything checked out fine, except for a minor thing. But Sierra has been doing my bi -yearly maintenance for about 5 years now which I truly believe helps to extend the life of my systems. Thank you Sierra and Wayne & Dan!”
