Taking Care of Our Customers Since 1987!

  • I signed up for another year of service maintenance with Lou today so that I can continue getting the best Air Conditioning and Heating service Las Vegas has to offer. It gives me great comfort to be a part of Sierra Care.

    “Once again Luis Rivera has exceeded my expectations. During my Air Conditioning service appointment he taught me how to check my condenser "receive" and "return" pipes so that I can ensure the system is functioning properly. And while Jacob, his partner on this trip, checked the attic for battery strength (all were strong) and potential vent leaks (there were none) and cleaned my drip pan of any potential rust to ensure no rusty air in the return air, Luis conditioned the outside fan/condenser unit so that it literally gleamed like brand new. Lou always takes the time to describe why things happen the way they do. Today when I had a question about noise on startup he described how the unit I have is very high efficiency and that their are circular plates in the motor housing that keep that gassy part of the refrigerant separated from the liquid refrigerant. He told me that on startup and shutoff these plates make a little extra noise so that the gas and liquid do not comingle. It is wonderful to have such a knowledgeable and caring service person. Lou treats me like a member of the family. I signed up for another year of service maintenance with Lou today so that I can continue getting the best Air Conditioning and Heating service Las Vegas has to offer. It gives me great comfort to be a part of Sierra Care.”

  • 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 appreciate the care they take in your home

    “I am impressed with Sierra Air. I have received service twice from their company. I appreciate the care they take in your home--wearing shoe covers and placing a drop cloth on the flooring before setting their ladder down. (And they bring their own ladder! I've actually had an HVAC technician ask to borrow one :) Tim D was extremely polite and professional. He was patient in taking the time to discover the problem I had called about. 'Cause wouldn't you know, the sounds I had been hearing weren't happening when he got there. He really took the time to figure out what might be causing the concern I had. I'm glad he didn't give up because he finally got to hear what I had been talking about. He had assured me that the problem we were having would be resolved that day. He also addressed another smaller concern. And he gave me tips on setting my thermostats and the types of filters I should use. Give Tim a bonus! :)”


  • 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.”
