At Sierra LLC Air Conditioning & Heating, we are proud to provide the Las Vegas area and surrounding communities with superior comfort and service, guaranteed! We know how hot the Las Vegas weather can get, and without a properly running air conditioning unit, you could be sweltering in the desert heat.

Our team of experienced and trusted professionals can help get your air conditioning and heating units in running order in a quick and cost-efficient manner. If you are interested in getting out of the heat and into the cool – contact a member from Sierra LLC Air Conditioning & Heating and schedule a free estimate, today!

We are proud to offer the following guarantees to all clients:

Comfort Guarantee:

We guarantee that the system(s) we have installed in your home will heat or cool your home as we have stated. If the temperature range we have promised is not achieved, we will replace the system at no charge. 100% Money-Back Installation Guarantee

No-Lemons Guarantee:

Sierra LLC Air Conditioning & Heating realizes that no manufactured equipment is 100% perfect 100% of the time. However, since our customers should expect to receive 100% of the cooling and heating value in which they’ve invested, we provide a “No-Lemons” guarantee, which simply means that as long as you purchase and commit to our SAM Agreement to properly maintain your home comfort investment, we promise:

We hope neither of these scenarios happen to you, but you can have peace of mind that Sierra LLC Air Conditioning & Heating will stand behind our equipment to your full satisfaction.

100% Money-Back Installation Guarantee:

Sierra LLC Air Conditioning & Heating has the utmost confidence in the caliber of work performed by our highly trained technicians. We ensure that you will be 100% satisfied with the operation of equipment installed by us. If you are not fully satisfied within the first year, we guarantee we will promptly correct the issue. Additionally, if the equipment is still not operating up to manufacturer’s specification, a manufacturer’s representative has verified the failure, and no other recourse is available, upon your written request, we will refund 100% of your purchase price. This 100% Money-Back Installation Guarantee applies only to complete systems installed by Sierra LLC Air Conditioning & Heating, along with any additional equipment installed on the same date.

Installation Workmanship Guarantee:

Our technicians are the most professionally trained in the Las Vegas area. We require an extensive pre-employment background check and require random ongoing drug testing to maintain employment. We ensure that our technicians will care for you home while working there. They will wear shoe covers to protect your floors and maintain cleanliness. They will also maintain a clean work area, use respectful language, and behave courteously in your home. If you believe that their performance does not meet these high standards, we’ll extend your SAM Agreement to include an additional service visit at no extra charge to you. All we ask is that you notify our office of your dissatisfaction on the same day the installation was completed.

Better Than We Found It Guarantee:

Your home is your greatest investment. Sierra LLC Air Conditioning & Heating understands that and guarantees that our technicians will not make or leave a mess or do anything to destroy your most valuable resource. We ensure that your home will be BETTER than we found it or we will pay for professionals to clean your home in its entirety. All we ask is that you notify our office of your dissatisfaction on the same day the installation was completed.

Lifetime Leak Guarantee:

Our installation workmanship is top-notch. Because Sierra LLC Air Conditioning & Heating is confident in the abilities of our technicians and the products that we install, we guarantee that there will be no leaks of greater than 6% in any duct systems installed by us. This guarantee applies to any accessible duct system installed by Sierra LLC Air Conditioning & Heating on the same date as the equipment installation. This guarantee does not apply to any damage that may be caused by rodents, natural disasters, or by the carelessness of other contractors including but not limited to home theater installers, cable or satellite companies, or duct cleaning contractors other than Sierra LLC Air Conditioning & Heating.

Apples-to-Apples Lowest Price Guarantee:

Sierra LLC Air Conditioning & Heating takes pride in never cutting corners. We’ve been in business long enough to know that other contractors may promise a lower price, but at what cost to the overall value? It’s very important to know what is and what is not included in any quoted price for a new cooling and heating system. Our technicians will show you the complete proposal so that you’ll know exactly what you are paying for. We challenge you to find a contractor with the same strict hiring and drug-testing practices, and with the same written guarantees who will provide you with a comparable installation. If you can provide a fully documented, honest, apples-to-apples comparison which includes the company’s written guarantees and employment practices, we will refund the difference to you, plus an additional $250 for your trouble. All we ask is that your request be in writing and submitted to our office within 14 days of signing a contract with Sierra LLC Air Conditioning & Heating or the installation date, whichever is the earliest. Your request must include the original published comparison of the competitor exhibiting the apples-to-apples comparison.
