Taking Care of Our Customers Since 1987!

I plan to renew when the current contract is up.
“Matt arrived on time as promised. Office called 30 minutes ahead to let me know that he was on his way. Very polite and efficient. Matt did the spring-summer system inspection. New system was installed last year - September so we are still on our maintenance contract for another year. I plan to renew when the current contract is up.”

Jared provided value-added service that educated me on the various options for more efficient and healthy air filtration. Thanks Jared for the friendly conversation, information and great inspection.
“Today, Thur, Mar 23, 2017, Jared provided us an inspection of our air conditioning. The best i can say about him may not be sufficient. He was professional, courteous, and knowledgeable. He even took his booties off and on after i told him he didn't need to. Jared was not hurried, he even was friendly to my sheepdog, Vinnie. Once he was done, he answered a number of my questions. Prior to starting, Jared gave me a packet of info to read through, and I had questions. He stepped through each of my questions offering a detailed explanation on the membership program, filtration systems, thermostats, and water heater. Jared provided value-added service that educated me on the various options for more efficient and healthy air filtration. Thanks Jared for the friendly conversation, information and great inspection. Were are set for the heat. Sierra LLC, the confidence you have placed in Jared is well-founded.”
