Stay Cool All Summer with Our Henderson AC Repairs

Being in the middle of the desert in the American Southwest, the Las Vegas area is prone to some of the wildest temperature swings in the country on a day to day basis. Some days during spring and fall may see temperatures drop to frigid levels overnight only to then reach sweltering highs during the day. When this is the case, many residents have to utilize both their heating and cooling systems on the same day, and they may rely heavily on one of these systems on other days throughout the year. All of that means eventually your HVAC equipment is going to need to be repaired, and the team at Sierra LLC Air Conditioning & Heating is ready to help when it does.

We fix all types of air conditioning and heating problems, including:

  • Faulty or dead blower fans
  • Electrical connection problems
  • Weak or low airflow
  • Strange sounds or smells
  • Compressor problems
  • Inconsistent temperatures

Sierra LLC Air Conditioning & Heating services all different makes and models of heating and cooling equipment, including both old and new units from some of the leading names in the industry like Trane, Carrier, and more! Our highly-trained techs are all NATE-certified and EPA-certified to offer you outstanding peace of mind as well as the finest craftsmanship you’ll find anywhere. We even use premium materials and genuine replacement parts to ensure that our repairs are complete and will last.

Why Won’t My AC Turn On?

Summer comes in hot in Henderson, the last thing you want to worry about is your air conditioner not turning on. But before you start thinking of replacements, there are things you can check for as to why the unit isn’t turning on.

Common reasons AC won’t turn on include:

  • Tripped Circuit Breaker: The circuit breaker protects your home from electrical overload. If you use too much electricity at once, it can trip the circuit breaker, causing your AC to stop working.
  • Broken Thermostat: The thermostat reads the temperature and tells the AC when to turn on. If it can’t accurately gage the temperature, it won’t be able to tell the AC and your air conditioner won’t turn on.

If neither of these is the reason why your AC won’t turn on, call Sierra LLC Air Conditioning & Heating. We can accurately diagnose the problem and provide reliable Henderson AC repair to keep you cool all year round.

  • 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.”


  • Fixed what four other companies just "put a band aid on"

    “Larry is the guy everyone should see before any other a/c person, he cut through the chase and fixed what four other companies just "put a band aid on". Our system was never better. Thank you for everything Larry!!”


  • This company has provided the best possible service

    “Outstanding service Moise and his supervisor. This company has provided the best possible service of any A/C company I have used in the past 10 years. I am so grateful for their honest, care and professionalism. Again, thank you!!!!”


  • 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.”
