HVAC Repair in Las Vegas

There are many reasons to call up an HVAC repair contractor in Las Vegas. If your system has gone too long without maintenance, it is fairly inevitable that an HVAC system will fail in some way, especially considering the intensity of a climate like the high-desert in Nevada with warm, long summers and cold nights.

Hiring a professional is the best choice to make when your system fails for a number of reasons:

  • You will save yourself time and a headache.
  • Bringing a professional on site regularly will extend the life of your HVAC system or water heater.
  • You will ensure that you and your household are as safe as possible.
  • HVAC systems that do not receive proper attention are the cause of property damage from things like fires and other life-threatening problems.

We offer 24/7 HVAC services in Las Vegas. Contact us online or call (702) 830-7553 to request a service.

  • 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.”


  • Sierra Air is a first class company.

    “Sierra Air is a first class company. It is a pleasure to do business with Sierra, after dealing with other outfits that don't return calls, or call late to cancel/reschedule service. Their communication skills are outstanding; they call to confirm appointments, and then call an hour before the tech shows up. Their techs are in uniform and always polite, and very conscientious and knowledgeable.”

  • 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.”
