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.

  • I have so much trust and faith in Sierra

    “Matt showed up today to help me with a balance air problem for our new inside and outside unit. He was told my problem and promptly went to work at correctly it. I ask him how he was familiar with air balancing? He told me his education back ground in the field and all the extra classes he has taken to get to where he is today. I knew I was in good hands. He also ended up doing my season checkup and with the weather we are having not to soon for me! He will have to order some parts but because the unit is so new it is a minor and no charge to us. He talked to his supervisor and said they would do it as soon as the parts get in! The bottom line is my happiness! I have so much trust and faith in Sierra that I know everything they do and tell me is what needs to be done. After years of doing business with them off and on I choose to stay with them as some others who just take advantage of folks. This company is honest.”


  • I would highly recommend these folks

    “Sierra Air and Jason Thack (30 years’ experience) are the BEST in Las Vegas area. First of all, my AC stopped working at about 4p on a Friday and to make matters worse, I live in a manufactured home and there are essentially, only 2 companies licensed to work on manufactured homes. I was very pleasantly surprised when the dispatcher, Michelle called and set up the service call last night and I asked about the service contract they offered on their website if I would be able to apply the reduced discounts and benefits to being a member for this repair job and the answer YES. I was told to expect a call from dispatcher about 30-45 min before they would arrive (between 8a-10a) and at 715a, they called to say he was on the way. He arrived at 8a and within 10 minutes, had diagnosed the broken fan 9a, had cool air blowing through the vents and he went ahead and did the 'spring' maintenance on the unit. Overall, a very pleasant experience and I was expecting a big $$ amt, being the weekend and July in Las Vegas and, all total work done including parts and warranties came to $1000....that included changing 3 capacitors to eliminate a near-future service call or two. I am grateful, cooled off in my house, and would highly recommend these folks (who discuss actual fees and costs PRIOR to any work being done).”

  • Excellent customer service and professionalism

    “I am so glad I contacted Sierra. They save me $10K. I originally contact Elite Heating and Cooling and they wanted to replace my entire furnace, coils and condenser in my air conditioner. When all I need done was the motor replaced in my furnace (less than $300). The part was still under warranty so I only had to pay for the installation. I'm so grateful to Sierra (Matt) for being COMPLETELY honest and not trying to sale me something I don't need. Excellent customer service and professionalism. HIGHLY RECOMMENDED.”
