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.
